Reasons Why Your Tooth Hurts When You Bite Down

Experiencing tooth pain when you bite down can be alarming and uncomfortable. This type of pain can have various causes, ranging from minor issues to more serious dental problems. Understanding the underlying reasons can help you seek the appropriate treatment and find relief.  


1. Cavities:

Cavities, or dental caries, are caused by tooth decay. When decay penetrates the enamel and reaches the sensitive inner layers of the tooth, it can cause pain, especially when biting down.

2. Cracked or Fractured Teeth:

A crack or fracture in your tooth can cause sharp pain when you apply pressure. These cracks can be caused by trauma, grinding, or biting down on hard objects.

3. Tooth Abscess:

An abscessed tooth is an infection that forms at the root of the tooth or between the gum and a tooth. This infection can cause severe pain, swelling, and sensitivity to pressure.

4. Gum Disease:

Gum disease (periodontitis) can cause the gums to recede and expose the tooth roots. This exposure can make teeth sensitive and painful when biting down.

5. Dental Trauma:

An injury to the tooth or surrounding tissues, such as a blow to the face, can cause pain and sensitivity when biting down.

6. Bruxism:

Bruxism, or teeth grinding, can wear down teeth and cause pain due to the pressure exerted on the teeth. This condition often occurs during sleep and can lead to chronic tooth pain.

7. High Dental Filling or Crown:

If a dental filling or crown is too high, it can cause your bite to be misaligned. This misalignment can create pressure and pain when you bite down.

8. Sinus Infection:

The roots of your upper teeth are close to the sinus cavities. A sinus infection can cause referred pain to these teeth, especially when you bite down.

9. Tooth Sensitivity:

Tooth sensitivity can be caused by worn enamel, exposed dentin, or receding gums. This condition can make teeth sensitive to pressure, temperature, and certain foods.

10. Impacted Wisdom Teeth:

Impacted wisdom teeth that are partially erupted or trapped under the gum line can cause pain and discomfort when biting down.

11. Malocclusion:

Malocclusion refers to misaligned teeth or an improper bite. This can cause uneven pressure on certain teeth, leading to pain and discomfort when biting down.


Tooth pain when biting down can be caused by a variety of dental issues. Identifying the underlying cause is crucial for finding the right treatment and relief. If you experience this type of pain, don’t ignore it—schedule an appointment with your dentist to diagnose and address the problem promptly. Taking proactive steps can help ensure your teeth stay healthy and pain-free.
