Tooth Pain When Biting – Causes, Relief & Treatments
 Experiencing tooth pain when biting or chewing can be more than just uncomfortable—it might signal a deeper dental issue. Many people describe it as, “It only hurts when I chew, not all the time,” which can make the cause feel elusive. At Wildhorse Dental, we help patients find the root of this pain and provide effective treatment for lasting relief.
Understanding Tooth Pain When Biting
Tooth pain triggered by biting is often different from generalized tooth sensitivity. Unlike a dull ache or temperature-triggered discomfort, pain when chewing typically results from pressure being applied to a compromised tooth or its surrounding structures.
This type of pain may present in different ways:
| • |
Sharp Pain - Often linked to cracks or acute damage.
|
| • |
Dull, Throbbing Pain - May suggest decay or inflammation.
|
| • |
Localized Pain - Focused on one tooth, often easy to identify.
|
| • |
Widespread Discomfort - Can indicate gum disease or bite misalignment.
|
| • |
Triggered by Heat, Cold, or Sweets - May point to sensitivity or deeper decay. |
Many people confuse general sensitivity with pressure-sensitive tooth pain, but identifying whether the pain is triggered only when biting helps narrow down the cause.
Most Common Causes of Tooth Pain When Biting
Pinpointing the exact source of your bite pain is crucial for treatment. Here are the most common causes behind this type of discomfort:
Cracked Tooth Syndrome
Cracked tooth syndrome involves small, often invisible fractures in a tooth. These cracks may not show up on X-rays but can cause sharp pain when biting or releasing pressure.
| • |
Microscopic Cracks - Not always visible but highly painful.
|
| • |
Triggered by Pressure - Especially when chewing hard foods like nuts.
|
| • |
Often Affects Molars - Due to high bite force. |
The classic symptom is a jolt of pain when releasing a bite, not when applying pressure.
Cavities or Tooth Decay
As tooth decay progresses, it can reach the inner layers of the tooth, causing pain with pressure or temperature.
| • |
Exposed Dentin or Pulp - Leads to sensitivity and discomfort.
|
| • |
Worse with Sweets or Cold - Sugar and temperature extremes intensify the pain.
|
| • |
Visible Signs - Such as holes or brown spots on the tooth. |
When cavities deepen, they often cause pain while chewing due to pressure on inflamed tissues.
Gum or Periodontal Disease
Though it feels like the pain is in the tooth, it may originate from infected gums. Periodontal disease causes inflammation that makes chewing painful.
| • |
Swollen or Bleeding Gums - Common symptom of gum disease.
|
| • |
Tooth Mobility - Loosened teeth can become painful under pressure.
|
| • |
Pain Felt Near Tooth Root - Often mistaken for toothache. |
Early intervention is essential to prevent worsening gum and bone loss.
Dental Restorations (Fillings or Crowns)
A new filling or crown may feel “off” if it’s slightly too high or misaligned. This can cause tooth pain when chewing.
| • |
High Spots - Uneven surface puts too much pressure on one tooth.
|
| • |
Poor Bonding - Can lead to microleakage or nerve irritation.
|
| • |
Pain in a Single Tooth - Especially noticeable after recent dental work. |
Bite adjustment or redoing the restoration often resolves the issue.
Root Canal Infection or Pulpitis
When the tooth’s nerve becomes inflamed or infected, it leads to severe pain, often triggered by biting or chewing.
| • |
Lingering Pain - Can persist even after chewing stops.
|
| • |
Nighttime Discomfort - Spontaneous pain while at rest is common.
|
| • |
Progressive Condition - Often requires a root canal for resolution. |
This is a serious condition that needs prompt treatment to avoid further damage.
Diagnosing the Cause of Your Tooth Pain
Proper diagnosis is essential to determine the cause of tooth pain when chewing. Since many issues aren't visible to the naked eye, dentists use multiple methods to uncover the problem.
| • |
Dental X-Rays - Reveal hidden decay, abscesses, or bone loss.
|
| • |
Bite Tests - Help pinpoint a cracked or pressure-sensitive tooth.
|
| • |
Thermal Sensitivity Tests - Identify nerve involvement.
|
| • |
Advanced Imaging - Cone-beam CT scans may be used for deeper investigation. |
Only a comprehensive dental evaluation can determine the exact source and best course of action.
Treatment Options for Tooth Pain When Chewing
Depending on the root cause, treatments will vary—but relief is possible with the right approach.
Cracked or Fractured Tooth
| • |
Crowns or Onlays - Protect the remaining tooth structure.
|
| • |
Root Canal - Necessary if the crack extends into the pulp.
|
| • |
Extraction - For teeth that are too damaged to restore. |
Cavities and Decay
| • |
Fillings - Restore minor to moderate decay.
|
| • |
Crowns - Protect teeth with extensive damage.
|
| • |
Root Canals - Required for deep decay affecting the pulp. |
Gum Disease
| • |
Scaling and Root Planing - Deep cleaning to remove bacterial buildup.
|
| • |
Antibiotic Therapy - Topical or oral medication to reduce infection.
|
| • |
Surgical Options - Needed in advanced periodontal cases. |
Bite Adjustment or Filling Repair
| • |
Occlusal Adjustment - Fine-tuning the bite for better alignment.
|
| • |
Filling Replacement - Replacing poorly bonded or high restorations.
|
| • |
Crown Recontouring - Adjusting crown height or fit. |
At-Home Relief Until You See a Dentist
If you can't get to a dentist right away, these home remedies can offer temporary comfort:
| • |
Avoid Chewing on Affected Side - Reduce stress on the painful tooth.
|
| • |
Cold Compress - Helps with inflammation or swelling.
|
| • |
Over-the-Counter Pain Relief - Ibuprofen or acetaminophen are effective.
|
| • |
Numbing Gels - Temporary relief for surface-level pain.
|
| • |
Saltwater Rinse - Soothes the gums and cleans the mouth.
|
| • |
Soft Foods Only - Avoid crunchy, hard, or very hot/cold foods. |
While these measures can reduce discomfort, they are not substitutes for professional care.
When to Call a Dentist
Knowing when to seek dental attention is critical. The sooner you act, the better the outcome.
| • |
Persistent or Increasing Pain - Indicates a progressing issue.
|
| • |
Visible Tooth Damage - Such as cracks, chips, or holes.
|
| • |
Swelling, Fever, or Pus - Signs of infection that require immediate care.
|
| • |
Pain After Dental Work - Could signal bite misalignment or restoration issues. |
Even if pain temporarily subsides, the underlying condition may still be active.

FAQs
Why does my tooth only hurt when I chew?
Pain when chewing often points to an issue that is triggered by pressure—such as a cracked tooth, inflamed pulp, or a high filling. It usually indicates structural damage or infection that becomes aggravated during biting.
Is it normal for a new filling to hurt when I bite down?
Mild discomfort after a new filling is common, but sharp or lingering pain when biting may mean the filling is too high or not properly bonded. A quick adjustment from your dentist can typically resolve the issue.
How do I know if I have a cracked tooth?
Symptoms of a cracked tooth include sharp pain when biting or releasing, sensitivity to temperature, and intermittent discomfort. These cracks may not appear on X-rays, so a clinical exam and bite test are essential.
Can gum disease cause pain when chewing?
Yes, advanced gum disease can cause pain during chewing due to inflammation, infection, and tooth mobility. While it may feel like a toothache, the pain originates from the supporting gum tissue. |
