Why does my tooth hurt when I bite down?

posted byMuse Dental GroupAugust 10, 2021

Every day, the dentists meet patients that say, "I have a tooth hurting when I chew." If you are a person whose tooth hurt, then this article is for you. If your tooth hurt when chewing, there are many possible causes.

There may be infected teeth, temporomandibular joint disease, sensitivity, or some other diseases. If you experience tooth pain or discomfort, it is imperative to see the dentist.

In this article, we are going to discuss:

Reasons for tooth hurt

If your tooth hurt when eating or biting down, it can be due to the following toothache causes :

Unlevelled Tooth, Filling, or Crown

If the teeth or dental crown is not leveled with other teeth, it may damage the teeth during chewing.

You may feel this discomfort after the treatment is complete and the numbing agent is exhausted.

Due to the uneven pressure applied during chewing, nearby teeth will also feel uncomfortable.


Have a tooth hurting or dental sensitivity after every meal? Cavities can leave you with prolonged pain after eating certain foods.

Many people are sensitive to sweets, such as breakfast pastries, flavored coffee, and even sodas when they have cavities.

Large cavities can clog food and cause pain. Severe tooth decay can irritate the nerves (pulp) inside the tooth, causing pain whenever you chew, bite, or eat food.

However, it is important to know that not every tooth cavity hurts. If the edges are rough, the enamel may have openings, or you feel weird when chewed, ask your dentist to evaluate it to prevent further deterioration of teeth.

Gum Recession

Gum recession may not cause tooth hurting when eating or chewing, but it can be very sensitive when pressure is applied to the tooth's exposed root.

If the food and the root surface collide while eating, you may feel pain in the area.

Injuries, teeth grinding, and clenching, periodontal disease , and excessive brushing can all cause gum recession.

Sinus or nasal congestion

The roots of the upper teeth are so close to the sinuses that additional pressure, infection, or congestion in the area may be the cause, especially if more than one tooth is injured.

This pain, also called sinus tooth hurting, is usually felt in the upper and back teeth close to the sinuses.

Dental abscess

If you experience pain in a particular tooth when you apply pressure, it could be because of an abscess around the tip of the tooth root.

This cyst or swelling in the interior of the bone puts pressure on the teeth and can cause tooth hurt if chewed or pushed down.

Abscess swelling and drainage may appear and disappear, and symptoms may worsen or be ignored.

Fistulas (small papules of the gums) usually appear near the teeth, and salty drainage flows out of the area. The only viable treatment to keep an abscessed tooth is root canal treatment .

Remedies for tooth hurting

Do you face tooth hurting? Your head is beating; gums are throbbing; the mouth is sour and soft. Please consult your dentist as soon as possible.

At the same time, use few remedies for short-term relief. Following are some remedies you can use before visiting the doctor:

  • Rinsing your mouth with warm salt water will help loosen debris in cavities or between your teeth. It also reduces swelling, relieves sore throats, and promotes healing.
  • Grind the fresh garlic cloves, mix them with a small amount of salt, and then apply the mixture to the affected tooth. Garlic contains a compound known as allicin, which has strong antibacterial properties.
  • You can add a drop of thyme essential oil to a glass of water to make mouthwash, which will relieve tooth hurt.
  • You can use a cold compress to reduce tooth hurting. Place an ice pack wrapped in a towel on the affected area for 20 minutes to use this method. You can repeat this whenever you start feeling pain.
  • Medicines like ibuprofen and acetaminophen can relieve the temporary pain of tooth hurting.
  • Clove has historically been used to treat tooth pain because the oil can effectively reduce inflammation and numb pain. To use this method, dab some clove oil on a cotton pad and apply it to the affected area.
  • You can use peppermint tea bags to reduce tooth hurt and soothe sensitive gums. To do this, let the used tea bag cool down before using it to the affected area. It should still be a little warm.

Why should you visit your dentist if you have tooth pain when chewing?

If you experience pain when chewing or biting, it is important to book an appointment with your dentist as soon as possible.

The dentist analyzes the teeth and surrounding tissue.

If you have a cracked tooth, the only cure will be casting.

Cracks do not automatically indicate the need for root canal treatment.

If the pulp is involved, a suitable temporary crown will suffice.

Then the dentist will re-evaluate next week. If the pain subsides, the dentist will continue to use the prosthesis.

If the pain persists, additional work is required.

The most important thing is to take immediate action.

You should not be late, hoping that the pain will disappear. Increased brushing and flossing will not cure your cracked teeth.

The longer you wait, the worse the situation will be.

Only if the dentist's assessment is delayed, the result will be more serious.

Tooth hurting during chewing usually indicates a greater oral hygiene problem.

It takes the eyes of a dental expert to determine if there is a more severe problem.


Tooth pain while chewing can be very frustrating. Uncertainty about the root cause is even more frustrating, especially if the dentist cannot diagnose first.

Unfortunately, endodontic examinations and x-rays may not provide in-depth information, which can lead to tooth breakage.

Either way, you cannot be sure if you do not go to the dentist for a detailed analysis of your oral health.
