Tooth pain when biting down can be caused by a cracked tooth, tooth decay, a damaged filling, or inflammation around the tooth. The pain does not automatically mean a root canal is necessary. A dentist in Abbotsford can assess the cause and recommend the appropriate treatment before the problem becomes more extensive.

Why Does My Tooth Hurt When I Bite Down?
Pain during chewing often occurs when pressure aggravates a damaged or inflamed part of the tooth or its supporting tissues. The location, timing, and type of pain can help a dentist narrow down the possible causes, but symptoms alone cannot confirm a diagnosis.

Common causes include the following.

1. A cracked or fractured tooth
A crack can cause sharp or unpredictable pain when chewing, sometimes particularly when releasing the bite. Temperature sensitivity may also occur. The symptoms can come and go, making the affected tooth difficult to identify without an examination.

A cracked tooth does not always require extraction. Treatment depends on the crack's location, depth, and extent, as well as the condition of the inner tooth. The American Association of Endodontists' guide to cracked teeth explains why timely assessment matters and how different types of cracks may require different treatments.

2. Tooth decay or a damaged filling
Decay can weaken the tooth and eventually affect deeper tissues. A filling that has loosened, fractured, or developed a problem around its edges may also make chewing uncomfortable.

A dentist may recommend a filling when damage is limited and enough healthy tooth structure remains. More extensive damage may require a different restoration.

3. A filling or crown that feels too high
Sometimes pain starts shortly after a new filling or crown has been placed. If the restoration contacts the opposing tooth too early, biting pressure may feel uneven or uncomfortable.

Contact the dental clinic that treated the tooth to arrange an assessment. Do not attempt to file or adjust the restoration yourself.

4. Inflammation or infection inside the tooth
The pulp is the soft tissue inside the tooth that contains nerves and blood vessels. Deep decay, trauma, or other damage can inflame or infect this tissue.

Pain when biting may be one symptom, but other signs can include lingering sensitivity to hot or cold, spontaneous aching, throbbing pain, or swelling. The American Association of Endodontists' tooth-pain guidance discusses how symptoms can point to different problems without replacing a professional examination.

5. Problems affecting the gums or tissues around the tooth
Inflammation in the supporting tissues, food trapped between teeth, or an infection around a tooth can also produce tenderness during chewing. Pain may therefore originate from more than the visible tooth itself.

Does Pain When Biting Down Mean I Need a Root Canal?
No. Pain during chewing has several possible causes, and some can be treated without root canal therapy.

Depending on the diagnosis, treatment may include:

A filling to restore a tooth with limited decay or damage.
A crown to protect a weakened or extensively restored tooth.
Root canal treatment when the pulp is irreversibly inflamed or infected and the tooth can be preserved.
Treatment for gum inflammation or infection when the supporting tissues are involved.
Extraction when the tooth is too damaged to be predictably restored.
The dentist will consider your symptoms, examination findings, the condition of the tooth, and any necessary X-rays before recommending treatment. If root canal treatment is being considered, you can review Mayfair Dental's root canal treatment service for an overview of the procedure.

What Should You Do Until You Can See a Dentist?
If biting causes pain, avoid repeatedly testing the tooth by chewing on it. These steps may help reduce irritation while you arrange an assessment:

Chew on the other side. Choose soft foods and avoid hard, crunchy, or sticky items that increase pressure.
Keep the area clean. Brush gently and floss carefully if food may be trapped between teeth.
Rinse gently with warm water. This can help clear loose food particles.
Avoid extreme temperatures if sensitive. Choose foods and drinks that do not trigger the pain.
Use pain medication only as directed. Follow the product label or advice from a qualified healthcare professional, taking your medical history and other medications into account.
Do not place aspirin directly on the tooth or gums, use household adhesives, or try to repair a crack or filling at home.

When Should You Seek Urgent Dental Care?
Contact a dentist promptly if the pain is severe, persistent, worsening, or interfering with eating or sleeping. A broken tooth, swelling around the tooth, pus, fever, or other signs of infection also need timely professional assessment.

Rapidly spreading swelling or difficulty swallowing or breathing needs emergency medical attention. Health Link BC provides additional information on tooth abscesses and signs of infection.

How Is Tooth Pain When Chewing Diagnosed?
A dental assessment may include:

Questions about when the pain began, where it occurs, and whether biting, temperature, or spontaneous pressure triggers it.
Examination of the tooth, existing restorations, gums, and surrounding tissues.
Bite or sensitivity tests when clinically appropriate.
Dental X-rays when needed to investigate decay, infection, or other changes that cannot be assessed by looking at the tooth alone.
A crack may not always be visible on an X-ray. The diagnosis therefore depends on the overall examination rather than one test alone.

Frequently Asked Questions
Can a cracked tooth hurt only when I chew?
Yes. Some cracks cause intermittent pain when biting or releasing pressure, while others cause temperature sensitivity or spontaneous discomfort. A dental examination is needed to determine whether a crack is present and how extensive it may be.

Can tooth pain when biting go away on its own?
Symptoms can fluctuate, but less pain does not necessarily mean the underlying problem has resolved. A damaged tooth or infection may continue to progress despite temporary relief.

Should I avoid chewing on the painful tooth?
Yes, avoid placing unnecessary pressure on it until the cause has been assessed. Soft foods and chewing on the opposite side may reduce irritation temporarily.

Does pain when biting always mean a root canal is needed?
No. The appropriate treatment may be a filling, crown, bite adjustment, treatment of the supporting tissues, root canal therapy, or another intervention depending on the diagnosis.

Can a tooth infection cause pain when chewing?
Yes. An infection may produce tenderness during chewing and may be accompanied by throbbing pain, swollen gums, pus, or facial swelling. Suspected infection needs prompt professional assessment.

When should I book an appointment for tooth pain?
Arrange an assessment for persistent, recurring, or worsening pain. Seek urgent care for severe pain, swelling, fever, trauma, or signs of infection. Difficulty breathing or swallowing requires emergency medical attention.

Conclusion: Get the Cause of Tooth Pain Checked
Tooth pain when biting down can result from several different dental problems, and the right treatment depends on the cause. An early assessment can help determine whether the tooth needs a filling, crown, root canal treatment, or another form of care.
