What Causes Pain When Biting?

Pain when biting can result from several different dental conditions, including:

• A cracked or fractured tooth
• A cavity that has reached the inner layers of the tooth
• An inflamed or infected tooth nerve
• A tooth abscess
• A high filling or crown that is affecting your bite
• Teeth grinding or clenching
• A loose or failing filling or crown
• Gum disease affecting the supporting tissues
• Trauma to a tooth

Because several of these conditions produce similar symptoms, an examination is the best way to determine the true cause.

Signs and Symptoms

You may notice:

• Sharp pain when biting down
• Pain when releasing your bite
• Discomfort while chewing certain foods
• One specific tooth that feels sore
• Sensitivity to hot or cold
• Swelling around the tooth or gums
• A feeling that your bite is “off”

Some patients experience pain only occasionally, while others notice it every time they chew.

When Should You See a Dentist?

You should schedule an examination if:

• Pain lasts more than a day or two.
• It hurts every time you chew.
• You notice swelling or drainage.
• A tooth feels loose or cracked.
• You recently had a filling or crown and your bite feels uneven.
• The pain is becoming more frequent or severe.

Prompt evaluation often allows treatment before the problem becomes more extensive.

How Is Pain When Biting Diagnosed?

Finding the cause of biting pain requires more than simply identifying which tooth hurts.

During your examination, Dr. Omeltschenko may evaluate:

• Digital X-rays
• Clinical photographs
• Bite alignment
• Existing fillings or crowns
• Cracks or fractures
• Tooth mobility
• Gum health
• The health of the tooth’s nerve

Special diagnostic tests may also be used to determine whether the discomfort is coming from the tooth, surrounding tissues, or your bite.

What Happens If It’s Left Untreated?

Ignoring pain when biting can allow the underlying problem to worsen.

Depending on the cause, delaying treatment may lead to:

• Larger tooth fractures
• Progressive tooth decay
• Infection of the tooth nerve
• Dental abscess
• Loss of additional tooth structure
• Tooth loss
• More complex treatment

Early diagnosis often allows for more conservative treatment and a better long-term outcome.

Possible Treatment Options

Treatment depends on the underlying cause of your symptoms.

Possible treatment options include:

• Bite Adjustment – if a filling, crown, or your natural bite is placing excessive pressure on a tooth.

• Tooth-Colored Fillings – for cavities or failing restorations.

• Same-Day Crowns – to protect cracked, weakened, or heavily restored teeth.

• Root Canal Therapy – when the tooth’s nerve has become permanently inflamed or infected.

• Tooth Extraction – if the tooth cannot be predictably restored.

• Nightguard Therapy – if grinding or clenching is contributing to excessive biting forces.

Our goal is to determine why your tooth hurts when you bite and recommend the most conservative treatment that provides long-term success.
