Cracked Tooth or Broken Filling: What to Do Before Your Visit

Dr Susan Pan, DDS — Wed, 15 Jul 2026 17:54:03 +0000

A cracked tooth, a chipped tooth, and a broken or lost filling are not always the same problem. A chip usually means part of the tooth surface broke off. A cracked tooth may have a fracture line that is hard to see. A broken or lost filling leaves part of the tooth exposed. Until you are seen, the goal is to protect the tooth, keep it clean, and watch for signs that the visit should be urgent.

What to do right away

Rinse gently with warm salt water if it feels comfortable. This can help clean the area without scrubbing it.
Use a cold compress on the cheek if there is swelling or discomfort.
Avoid chewing on that side until the tooth is checked.
Choose soft foods such as yogurt, eggs, soup, pasta, or mashed foods.
Stay away from sticky, hard, crunchy, very hot, or very cold foods if they trigger pain or sensitivity.
Keep the area clean by brushing carefully around the tooth and flossing gently if the space allows it.

What not to do

Do not put aspirin directly on the tooth or gum. Do not use superglue, household adhesive, or other rough do-it-yourself repair methods. Those can irritate the tissues and make later treatment harder. Temporary over-the-counter dental repair products may be a short-term bridge, but they are not a .

When the appointment should be urgent

Call for prompt dental care if you have significant pain, sensitivity that is getting worse, swelling, fever, a bad taste or drainage, a tooth that feels loose, or a tooth injury after trauma to the jaw or face. A chipped or fractured tooth can still need prompt assessment even if it is not completely broken off.

Seek emergency medical help right away if you have trouble breathing, trouble swallowing, facial swelling that is rapidly getting worse, or you suspect a jaw fracture.

What the dentist may check

At the visit, the dentist will look at the tooth, the filling, your bite, and the surrounding tissues. The repair plan depends on what is found. In some cases the tooth may only need smoothing or a new filling. In others, a crown or another repair may be recommended. The exam helps show whether the tooth structure is stable enough to fix and what option makes the most sense.

Root Canal or Antibiotics for Tooth Pain? What Current Evidence Says

Dr Susan Pan, DDS — Thu, 26 Mar 2026 19:03:43 +0000

Why people often think antibiotics should fix tooth pain

When tooth pain is intense, it is understandable to assume an infection is present and that antibiotics should solve the problem. In reality, that is not always how dental pain works.

Many painful teeth are not treated based on pain level alone. They are treated based on the diagnosis. A severely painful tooth may have inflammation inside the pulp, which is the soft tissue and nerve in the centre of the tooth. In many of these cases, antibiotics do not address the source of the problem well because the tooth itself needs local dental treatment.

This matters for patients and families because waiting for antibiotics alone to help can delay the care that actually relieves the cause of the pain.

What dentists mean by pulpitis, infection, and root canal treatment

The pulp is the living tissue inside a tooth. It contains nerves, blood vessels, and connective tissue. If the pulp becomes irritated by deep decay, a crack, trauma, or a leaking restoration, it can become inflamed. Dentists call this pulpitis.

Not all pulpitis is the same. Sometimes the pulp is irritated but may still recover. In other cases, the pulp is so inflamed that it is unlikely to heal. In plain language, that is often what dentists mean when they talk about irreversible pulpitis. A tooth can also progress from inflammation to pulp death and infection around the root.

A root canal treatment is a procedure used when the pulp is irreversibly inflamed or infected and the tooth is still a good candidate to save. The inside of the tooth is cleaned, disinfected, and sealed so the tooth can often be kept in function. In other situations, the more appropriate options may be vital pulp therapy, a restoration, drainage, monitoring, or extraction. The right choice depends on what is happening inside and around that specific tooth.

When antibiotics usually do not help

Current guidance is quite consistent on this point. Choosing Wisely Canada states that antibiotics should not be prescribed for irreversible pulpitis, because treatment is directed at the tooth rather than with antibiotics alone. The American Dental Association similarly recommends against antibiotics for most pulpal and certain periapical conditions when definitive dental treatment is available.

For patients, the key message is simple: uncomplicated toothache from inflamed pulp usually needs dental treatment, not just an antibiotic prescription.

That definitive treatment may include removing decay, placing a protective restoration, performing vital pulp therapy, starting root canal treatment, draining a localized infection when indicated, or removing a tooth that cannot be predictably restored. Which option is appropriate depends on the diagnosis, not on whether the pain feels mild or severe.

Recent reviews add a timely public health point. A 2024 scoping review and a 2025 systematic review found that antibiotics continue to be prescribed for pulpitis more often than the evidence supports. The 2025 review estimated that about one in five dentists prescribed antibiotics for pulpitis across included surveys, but the authors also rated the certainty of that evidence as very low because the studies were quite variable. Even with that limitation, the overall message supports better antibiotic stewardship and better access to timely dental care.

When antibiotics may be needed

Antibiotics do have an important role in some dental infections. They may be appropriate when there are signs that the infection is spreading or affecting the body more broadly, or when a dentist identifies a higher-risk situation based on the examination and the patient’s medical history.

Examples may include facial swelling, spreading infection, fever, malaise, deeper space involvement, or selected situations in patients who are medically vulnerable. In these cases, antibiotics are usually an addition to definitive dental treatment, not a substitute for it.

This is why it is important not to self-start leftover antibiotics or assume that a short-term reduction in pain means the problem is resolved. The source of the issue may still be present inside the tooth or surrounding tissues.

How dentists decide what treatment is needed

Because not all tooth pain means the same thing, dentists use several pieces of information together before recommending treatment.

An assessment may include asking when the pain started, whether it lingers after hot or cold, whether it wakes you at night, whether biting makes it worse, and whether swelling is present. Your dentist may examine the tooth, test the pulp’s response, check the surrounding gum and bone, and take X-rays. In some situations, additional tests are needed to tell whether the tooth is irritated, irreversibly inflamed, infected, cracked, or affected by a problem that feels like tooth pain but comes from another source.

This careful diagnosis is important because a painful tooth does not automatically mean a root canal, and a less painful tooth is not always less serious.

Root canal, pulp therapy, extraction, or monitoring: what the options mean

Patients often ask whether every painful tooth needs a root canal. The answer is no.

Monitoring or a restoration may be reasonable if the pulp is irritated but likely to recover after decay is removed and the tooth is sealed well.

Vital pulp therapy may be considered in selected cases when part of the inflamed pulp can be treated while preserving healthy tissue.

Root canal treatment may be recommended when the pulp is irreversibly inflamed or infected and the tooth can be predictably saved and restored.

Drainage may be needed if there is a localized abscess that requires release of pressure and infection control.

Extraction may be the better option if the tooth is too damaged, too cracked, not restorable, or unlikely to do well even with treatment.

The choice depends on the condition of the tooth, the surrounding bone and gums, symptoms, X-ray findings, the long-term restorability of the tooth, and the patient’s overall needs and preferences.

Pain relief while waiting for treatment

When appropriate for the individual patient, pain relief often involves local dental treatment plus non-opioid analgesics. The American Dental Association and the CDC both support the use of non-opioid pain relief strategies for many forms of acute dental pain.

That said, medication advice should always be tailored to the person. Age, medical conditions, pregnancy, kidney disease, stomach ulcers, blood thinners, allergies, and other factors can affect what is safe. It is best to follow the advice of your dentist, pharmacist, physician, or nurse practitioner based on your own health history.

Red flags that need urgent or emergency assessment

Some symptoms suggest that a dental problem needs urgent assessment and should not wait.

Seek urgent dental or medical care if you have:

Facial swelling
Fever
Difficulty swallowing
Difficulty breathing
Feeling very unwell
Rapidly worsening pain or swelling

These symptoms can suggest a spreading infection or a more serious complication. If breathing or swallowing is affected, emergency assessment is especially important.

Why antibiotic stewardship matters

Using antibiotics only when they are likely to help protects both individual patients and the wider community. Unnecessary antibiotics can cause side effects such as diarrhea, allergic reactions, and drug interactions. Overuse also contributes to antimicrobial resistance, which makes infections harder to treat over time.

For dental patients in Hamilton and across Canada, this is one reason evidence-based diagnosis matters so much. The goal is not to withhold treatment. The goal is to use the treatment that fits the actual problem.

Questions to ask your dentist

If you or a family member has severe tooth pain, these questions can help guide the conversation:

What is the diagnosis?
Is the pulp irritated, irreversibly inflamed, or infected?
Is the tooth savable?
Would vital pulp therapy, root canal treatment, extraction, or another option make the most sense here?
Are antibiotics actually indicated in this case?
What warning signs should I watch for at home?
What is the safest way for me to manage pain until treatment is completed?

What patients should remember

Severe tooth pain is a reason to seek prompt dental assessment, but it does not automatically mean antibiotics are the answer. For uncomplicated pulpitis, the evidence and major professional guidance support treating the tooth itself. Depending on the diagnosis, that may mean a filling, vital pulp therapy, root canal treatment, drainage, extraction, or careful monitoring.

A root canal is one important option when the pulp is irreversibly inflamed or infected and the tooth can be saved. Antibiotics still have a role when infection is spreading or causing systemic illness, but they are usually not a substitute for definitive dental care.

The most helpful next step is often the simplest one: get the tooth assessed, ask for the diagnosis in plain language, and make sure the treatment plan matches what is actually happening.
