What dentistry means in Hamilton — and what it does not mean

Dr Susan Pan, DDS — Wed, 01 Jul 2026 17:34:15 +0000

What people usually mean by holistic or biological dentistry

If you searched for biological dentistry in Hamilton, you are probably looking for dental care that treats the mouth as part of the whole person. That is a reasonable goal. In practice, the value is not the label itself. The value is whether the dentist starts with a real diagnosis, explains why a test or treatment is being recommended, and helps you make an informed decision.

That is the spirit behind our dentistry topic hub: whole-person care, not a separate system that replaces evidence-based dentistry.

What whole-person dentistry should include

A thoughtful consultation should look at more than the tooth that hurts. It should include your medical history, medications, allergies, past dental care, symptoms, anxiety level, and the practical concerns that matter to you, such as comfort, cost, timing, and how much treatment you want to do at once.

Good planning also includes informed consent. That means the dentist explains the diagnosis, the options, the likely benefits, the limits, the risks, and what may happen if you wait. Ontario dental standards support evidence-based care and clear communication so patients can make informed choices.

Whole-person care can also include questions about sleep, grinding, dry mouth, diet, tobacco use, and home care habits. Those details help the dentist choose the right plan, whether that is a checkup, radiographs, fluoride, a filling, gum treatment, a crown, oral surgery, or something else.

What standard evidence-based care still looks like

A holistic approach does not mean saying no to routine dental tools by default. Exams, radiographs when they are clinically indicated, fluoride, restorations, periodontal care, and oral surgery are still part of good dentistry when they are needed.

Those tools are not used just because they exist. They are used because they can help find disease earlier, prevent avoidable damage, relieve symptoms, or restore function. The right question is not whether a treatment is “natural.” The right question is whether it matches the diagnosis and the patient’s goals.

What dentistry does not mean

dentistry does not mean detoxes, -all supplements, or non-dental therapies being presented as proven s. It does not mean rejecting radiographs or fluoride for everyone. It does not mean assuming that “natural” automatically means safer, better, or more effective.

It also does not mean that a dentist can diagnose or systemic disease from the mouth alone. Oral health is connected to overall health, and the connection is important, but the evidence is not the same for every condition. Some links are well established, some are associative, and some are still being studied.

If an office recommends an add-on such as a supplement, herbal product, ozone, or other alternative therapy, it is fair to ask whether it is meant as support or as a substitute, what the evidence shows, what the risks are, what it costs, and what the alternatives are.

Questions worth asking before you agree to care

What problem are you treating, and how do you know?
What will this test or treatment change in my care plan?
What are the benefits, limits, and possible downsides?
What happens if I wait, and what signs would mean I should come back sooner?
Are any supplements or alternative therapies optional add-ons, or are you saying they replace standard dental treatment?
Why are radiographs, fluoride, or another routine tool being recommended in my case?

A calm next step in Hamilton

If you want a careful, evidence-based conversation, Excel Dental in Hamilton can review your symptoms, explain why a recommendation is being made, and talk through alternatives in plain language. You can start with this dentistry topic hub and use that information to decide what makes sense for you.

Fotona Laser Dentistry for Root Canals: What the Evidence Says About Comfort, Cleaning, and Limits

Dr Susan Pan, DDS — Tue, 31 Mar 2026 23:33:15 +0000

What patients mean when they ask about a Fotona laser root canal

When patients ask whether a Fotona laser can be used for a root canal, they are usually asking about one specific part of treatment: using an Er:YAG laser to activate the cleaning fluid inside the root canal.

That is an important distinction. A laser does not replace a root canal. Standard root canal care still depends on a careful diagnosis, shaping the canals with instruments, using disinfecting solutions, sealing the canal system well, and following the tooth over time.

In plain language, a Fotona laser may be used as an added tool during the cleaning phase. It is not a shortcut, and it is not a guarantee of a better result in every case.

How Er:YAG laser activated irrigation fits into a standard root canal

A root canal is done to treat infection or inflammation inside a tooth. After the dentist or endodontist reaches the inside of the tooth, the canals are cleaned with instruments and rinsed with disinfecting solutions. Because root canals can have tiny branches and irregular spaces, clinicians have looked for ways to help those fluids move more effectively.

This is where laser-activated irrigation comes in. Er:YAG refers to a type of laser with a wavelength that interacts strongly with water. In endodontics, that property can be used to create rapid fluid movement inside the canal. The goal is to improve how the irrigating solution circulates, especially in areas that instruments may not fully touch.

You may also hear branded or technical terms such as PIPS and SWEEPS. PIPS stands for photon-induced photoacoustic streaming. SWEEPS stands for shock wave enhanced emission photoacoustic streaming. Patients do not need to memorize the names. The practical point is that these are pulsed Er:YAG methods designed to agitate the cleaning fluid inside the canal rather than replace the usual steps of treatment.

A 2024 review in Photobiomodulation, Photomedicine, and Laser Surgery found that erbium lasers have shown the ability to disrupt biofilm in root canal systems, which helps explain why clinicians are interested in them as an adjunct. At the same time, this type of evidence is still stronger for mechanism and laboratory rationale than for proving clear clinical superiority in every patient situation.

What the best recent evidence says about short term pain after treatment

The most patient-relevant question is often simple: will I be less sore afterward?

A 2026 systematic review and meta-analysis in the Journal of Endodontics compared laser-activated irrigation with ultrasonically activated irrigation for postoperative pain after root canal treatment. The overall finding was cautious but clinically meaningful: laser-activated irrigation was associated with lower short-term postoperative pain, especially in the first 24 to 48 hours, and the benefit appeared strongest with pulsed Er:YAG approaches such as PIPS or SWEEPS.

That does not mean every patient will notice a difference. It also does not mean the root canal will feel easy afterward. Some soreness can still happen after any well-done root canal because irritated tissues around the tooth may need time to settle.

Still, if a dentist recommends Er:YAG laser activation as part of root canal care, the best recent evidence supports a careful statement that it may improve comfort in the first day or two for some patients when compared with ultrasonic activation.

What the evidence says about cleaning, bacteria, and healing limits

This is where it is important to be balanced.

Patients sometimes hear that lasers clean better, kill more bacteria, or make treatment more successful. Those claims need context. A 2024 randomized clinical trial in patients with apical periodontitis compared SWEEPS with passive ultrasonic irrigation and found similar effects on bacterial load and inflammatory markers between the two methods. In other words, one well-designed clinical study did not show a clear advantage for SWEEPS on those measures in that patient group.

That does not mean lasers have no value. It means the evidence is mixed, and the strongest support right now is for possible short-term comfort benefits, not for broad claims of better long-term healing or consistently better bacterial reduction in every case.

The American Association of Endodontists has also taken a cautious position. Its statement on lasers in dentistry says laser use as an aid in disinfection is more promising than laser use for canal preparation, but it also notes that effects on the clinical outcomes of root canal therapy were not established. That is an important message for patients. Even when a laser is used, the foundations of success are still diagnosis, case selection, good cleaning chemistry, careful shaping, sealing, and restoration of the tooth.

It is also important not to generalize findings from Er:YAG irrigation techniques to all dental lasers. Different wavelengths, tips, settings, and treatment goals are not interchangeable.

What specialty guidance and Ontario standards mean for safe use

In Ontario, technology does not replace professional judgment. The Royal College of Dental Surgeons of Ontario sets expectations around diagnosis, treatment planning, informed consent, recordkeeping, and competence. That matters whenever a dentist recommends a device-assisted approach.

For patients in Hamilton and across Ontario, this means a few practical things. Your dentist should explain why a laser is being considered for your case, what the expected benefits and limits are, what alternatives exist, and whether there are additional costs. Consent should be based on understandable information, not on brand names or marketing language.

It also means the clinician using the technology should be appropriately trained and should use it within the standard of care. A laser can be a useful adjunct in selected cases, but it is not a substitute for sound endodontic technique.

Questions to ask your dentist before choosing laser assisted root canal care

If laser-assisted irrigation is being offered, these questions can help you make an informed decision:

Why are you recommending a laser for my root canal specifically?
Is the goal to improve short-term comfort, cleaning, or both?
What does the evidence show for my type of case?
Will a laser replace any standard part of treatment, or is it being used as an added step?
Are there added fees?
What alternatives do I have, including conventional irrigation activation methods?
Who will perform the treatment, and what training do they have with this technique?

What patients in Hamilton should take away

For patients and families, the most helpful takeaway is this: a Fotona laser may be used during a root canal to help activate the cleaning fluid, not to replace the root canal itself.

Recent evidence suggests that pulsed Er:YAG laser activation may reduce soreness in the first 24 to 48 hours after treatment for some patients. That is encouraging, but it should be kept in proportion. The evidence does not show that lasers reliably replace standard cleaning steps, guarantee a more successful result, or improve long-term healing in every case.

When this technology is used thoughtfully, with proper diagnosis and informed consent, it may be a reasonable adjunct in selected root canal cases. The right choice still depends on the tooth, the infection, the anatomy, the clinician’s training, and a careful discussion of benefits, limits, alternatives, and cost.

For most patients, the best question is not whether a laser sounds advanced. It is whether it makes sense for their specific tooth and treatment goals.

What AI in Dentistry Can and Cannot Do for Patients in Hamilton

Dr Susan Pan, DDS — Sat, 28 Mar 2026 01:02:50 +0000

Why patients in Hamilton are hearing more about AI in dentistry now

Artificial intelligence, often called AI, is now a real topic in dental regulation and professional guidance in Ontario. In March 2025, the Royal College of Dental Surgeons of Ontario, or RCDSO, reported that it had developed draft guidance on artificial intelligence in dentistry to help dentists use these tools responsibly and ethically. The RCDSO also noted very strong professional interest in the topic through its education programming.

For patients and families in Hamilton, that matters because it means AI is not just a marketing term. It is being discussed as a practical, ethical, and clinical issue. The important point is that AI in dentistry is being treated as a support tool that must fit within professional standards, not as a replacement for clinical care.

What AI in dentistry usually means in a dental office

In plain language, AI in dentistry usually means software that helps analyze dental images such as X-rays. It may highlight areas that look suspicious for decay, bone changes, or other findings so the dentist can review them more carefully.

Right now, the strongest use case is image interpretation support. In other words, AI may act like a second set of eyes on a radiograph. It does not know your symptoms, your medical history, how long a problem has been present, whether a tooth responds normally on testing, or what matters most to you when making treatment decisions.

That is why AI support is very different from an independent diagnosis. A diagnosis still depends on the clinical exam, your history, risk factors, the quality and type of image taken, and the dentist’s judgment.

Where AI may help: reviewing radiographs for possible caries or periapical findings

Recent research suggests that AI shows promise in selected imaging tasks, especially when reviewing dental radiographs. A 2025 systematic review and meta-analysis on AI for caries detection found encouraging accuracy overall, but also substantial variation between studies. That variation matters because it means results may not be the same across different image types, software systems, patient populations, and office settings.

A broader 2024 systematic review of AI in dentomaxillofacial imaging found that many studies focused on narrow imaging tasks such as tooth identification, cephalometric landmarks, and lesion detection, including periapical findings. The review concluded that results were promising, but that further studies are still needed before these models can be confidently integrated into everyday practice across real-world scenarios.

For patients, the practical takeaway is simple. AI may help your dentist review an image more consistently or notice an area worth a second look. That is useful, but it is not the same as proving better long-term health outcomes for every patient.

What the newer evidence shows: modest improvement, especially fewer false positives in one 2025 trial

One of the more useful newer studies for patients is a 2025 randomized controlled trial on diagnosing periapical radiolucencies on panoramic radiographs. In that study, AI assistance improved overall diagnostic accuracy from 91.6 percent without AI to 93.3 percent with AI. The main improvement was a reduction in false positives, meaning dentists were less likely to incorrectly label a finding as disease when AI support was available. Sensitivity stayed about the same.

The same trial found that less experienced dentists benefited the most, and AI support was associated with more conservative treatment decisions. That is encouraging because fewer false positives may reduce the chance of overtreatment in some situations.

Still, this was one study on one type of finding, using one imaging context. It should not be treated as proof that AI improves all areas of dental diagnosis or treatment planning.

Why the evidence is promising but still limited

The current evidence base is growing, but it has important limits. Many studies look at how well software performs on image interpretation tasks rather than whether patients do better over time. Studies also differ in the types of radiographs used, the quality of the datasets, the reference standards, and the experience level of the dentists involved.

In the 2025 caries review, statistical heterogeneity was high, which is a technical way of saying the study results varied a lot. When that happens, it becomes harder to apply one summary number to every patient and every practice.

That is why a careful, evidence-based message is more helpful than hype. AI may be useful in certain tasks, especially radiographic review, but real-world clinical benefit is still being clarified.

What AI cannot do on its own: diagnose you as a whole person or choose treatment in context

Good dental care is about more than reading an image. A small shadow on an X-ray can mean different things depending on whether you have pain, swelling, a cracked tooth, past root canal treatment, a history of frequent decay, dry mouth, gum disease, trauma, or other risk factors.

AI cannot examine your mouth, test a tooth, feel a swelling, discuss your goals, or weigh treatment options in the context of your health and preferences. It also cannot replace informed consent. Even if software flags a possible problem, your dentist still needs to explain what was seen, how certain the finding is, what the alternatives are, and whether monitoring, additional testing, or treatment makes sense.

Just as important, AI does not make unnecessary X-rays appropriate. Choosing Wisely Canada recommends that dental X-rays and other imaging be prescribed based on each patient’s medical and dental history, clinical findings, and risk assessment, not on a routine schedule. Technology should support justified care, not expand imaging without a reason.

Questions patients can ask if AI is mentioned during their visit

If your dentist mentions AI, it is reasonable to ask a few practical questions:

How is the software being used in my case?
What did the software flag on the X-ray?
What do you agree with, and what do you disagree with?
How certain are you that this finding is clinically important?
Would your recommendation change without the software?
Do I need this image based on my symptoms and risk factors?

These questions support shared decision-making. They can help patients understand the difference between a software prompt and a clinical diagnosis.

Bottom line: useful support tool, not a substitute for evidence-based dental care

For patients in Hamilton, the most accurate way to think about AI in dentistry today is as a support tool. It may serve as a second set of eyes for some X-rays, and newer research suggests it can modestly improve performance in certain imaging tasks, especially by reducing some false positives. That said, the evidence is still evolving, and the benefits are not uniform across every condition or setting.

The final diagnosis and treatment plan should still come from a dentist who reviews your symptoms, examines you, considers your history and risk factors, and explains your options clearly. Good care still starts with the right exam, the right radiographs when they are actually indicated, and a thoughtful conversation about what is best for you.

CBCT Scan in Dentistry: What Patients in Hamilton Should Know

Dr Susan Pan, DDS — Sun, 15 Mar 2026 01:17:57 +0000

Understanding CBCT in Dental Care

CBCT stands for cone beam computed tomography. It is a specialized type of dental imaging that creates detailed three dimensional images of your teeth, jawbone, nerves, and surrounding structures.

Unlike traditional dental X-rays, which produce flat two dimensional pictures, a CBCT scan allows your dentist to see structures from multiple angles. This can be very helpful when planning certain treatments or investigating complex dental problems.

As a dentist practicing in Hamilton since 1986, I use CBCT selectively and only when the additional information will meaningfully improve diagnosis or treatment planning. It is not needed for every patient or every dental visit.

How CBCT Is Different from Regular Dental X-rays

Standard dental X-rays are excellent for detecting cavities, monitoring bone levels around teeth, and identifying many common conditions. They use a relatively low radiation dose and remain the first line imaging choice for most routine care.

A CBCT scan captures a larger volume and produces a three dimensional image. This allows us to:

See the exact position of impacted teeth
Assess bone volume before placing dental implants
Evaluate complex root canal anatomy
Examine jaw joint structures in selected cases
Investigate pathology such as cysts or unusual lesions

Because CBCT involves more radiation than routine dental X-rays, professional guidelines emphasize that it should only be used when the expected diagnostic benefit outweighs the risk.

When Is a CBCT Scan Recommended?

According to guidance from the Royal College of Dental Surgeons of Ontario and recommendations from professional organizations such as the American Association of Endodontists and the American Association of Oral and Maxillofacial Surgeons, CBCT should be used when conventional imaging does not provide enough information.

Common evidence supported uses include:

Dental implants. CBCT helps measure bone height and width and identify important structures like the inferior alveolar nerve or sinus cavities before surgery.
Complex root canal cases. The American Association of Endodontists notes that CBCT can help identify extra canals, root fractures, or persistent infections when standard imaging is inconclusive.
Impacted teeth. For example, wisdom teeth near major nerves.
Assessment of jaw pathology. Suspicious cysts, tumors, or bone abnormalities sometimes require three dimensional imaging.
Orthodontic assessment in selected cases. Particularly when evaluating impacted canines or complex skeletal relationships.

CBCT is not recommended for routine screening. Choosing Wisely Canada advises that imaging should be based on individual risk and clinical findings, not used automatically.

Is CBCT Safe?

All X-ray based imaging involves radiation exposure. The key principle in dentistry is ALARA, which stands for As Low As Reasonably Achievable. This means we only prescribe imaging when it is justified and we use the lowest effective dose.

CBCT generally involves more radiation than a single dental X-ray but significantly less than a hospital based medical CT scan. The exact dose depends on the machine settings and the size of the area scanned.

Regulatory standards in Ontario, including guidance from the Royal College of Dental Surgeons of Ontario, require dentists to justify and document the need for CBCT imaging and to ensure appropriate training in interpretation.

For children and adolescents, extra care is taken. The decision to use CBCT must be carefully considered because younger patients are more sensitive to radiation. In many cases, conventional imaging is sufficient.

How a CBCT Scan Works

The scan itself is quick and comfortable. You will either sit or stand while the machine rotates around your head for about 20 to 40 seconds. You do not need needles or contrast dye.

The resulting images are processed into a three dimensional model that can be viewed on a computer. This allows your dentist to examine cross sections and measure structures with precision.

Why Accurate Imaging Matters for Overall Health

Precise diagnosis supports safer and more predictable treatment. For example:

In implant dentistry, accurate bone measurements reduce the risk of damaging nearby nerves or sinus cavities.
In endodontics, identifying hidden canals can help resolve persistent infection and reduce the need for retreatment.

Oral infections and untreated dental disease can affect overall wellbeing. Public Health Ontario and the Government of Canada both emphasize the importance of early diagnosis and appropriate treatment in maintaining oral health as part of overall health. CBCT is one tool that can assist when complex conditions are present, but it is not a substitute for preventive care.

Questions to Ask Your Dentist About CBCT

If your dentist recommends a CBCT scan, consider asking:

Why is this scan necessary in my specific case?
Would regular X-rays provide enough information?
How will the results change my treatment plan?
What are the radiation considerations for me or my child?

An evidence based approach means imaging should always be tied to a clear clinical reason.

Balanced, Individualized Care in Hamilton

Every patient is different. Some dental conditions are straightforward and can be managed with conventional imaging. Others are more complex and benefit from three dimensional assessment.

My goal is always to combine careful clinical examination, appropriate imaging, and open discussion so you can make informed decisions about your care. CBCT is a powerful diagnostic tool when used thoughtfully and responsibly.
