My Back Teeth Keep Biting My Cheek

Accidentally biting the inside of your cheek is irritating and can be painful mainly if it keeps happening repeatedly. If you have a recurring cheek-biting problem with your back teeth, it might be worth seeing a dentist to see if the issue can be corrected.

Why Do I Keep Biting My Cheek with My Back Teeth?

“My back teeth keep biting my teeth. Why is this happening to me”? First, take a deep breath and try to stay calm. Stressing out will only exacerbate the issue.

As to why it is happening, you might find the answer below.

Misalignment

One of the most common reasons for repeated cheek biting is a teeth or jaw misalignment. Malocclusion condition means the upper and lower teeth aren’t resting together correctly. 

A malocclusion makes it more likely for your teeth to catch the inside of your cheek when you bite down. According to the American Association of Orthodontists, crossbites are among the most common forms of malocclusion. Wisdom teeth can also push your teeth out of alignment as they grow in, resulting in the same problems as a crossbite or misaligned jaw.

Fast or Careless Chewing

If you tend to eat fast mainly while focusing on another task, you are more likely to be careless about where you’re putting your teeth. This makes it more likely for you to bite the inside of your cheek while chewing. You can also run into trouble if you tend to favor one side of your mouth more than the other while chewing.

Ill-Fitting Dental Devices

Braces and retainers are meant to resolve dental issues, but if they are not sized properly, they can cause a whole new set of problems. Poorly fitted dental devices can cause teeth to misalign, making it more likely that you will accidentally bite your cheek.

Stress

If you ask, “My back teeth keep biting my cheek – what’s going on?” you should also ask yourself “Am I more stressed out than usual?” Biting the inside of your cheek can be a conscious or unconscious coping mechanism for stress and anxiety. Repetitive cheek biting creates a raised ridge along the inside of the cheek, making it more likely that you will accidentally bite yourself while chewing.

My Back Teeth Keep Biting My Cheek. What Can I Do?

To stop repeated cheek biting by back teeth, you will likely need a dentist to evaluate what is happening inside your mouth.

The following treatments and home remedies may help provide relief:

• Rinsing your mouth with a saltwater gargle to reduce inflammation
• Taking over-the-counter pain relief medication
• Talking to a doctor psychologist about ways to reduce stress
• Wearing a mouthguard while you sleep

If you’re dealing with soreness or injury from repeated cheek biting, understanding how to heal a cut in your mouth can also help speed up recovery and reduce discomfort.

Inner Cheek Bite Treatment Options That Actually Work

If you keep biting inside of cheek tissue—especially near your back teeth—the most effective solution depends on what is causing the problem in the first place. In many cases, repeated cheek biting is not random. Instead, it usually happens because of subtle bite alignment changes, irritation from dental appliances, or repeated swelling in the same area that makes the tissue easier to catch again while chewing.

A dentist can evaluate how your back teeth come together and determine whether the issue is structural, behavioral, or a combination of both. Identifying the cause early helps prevent irritation from becoming a long-term habit that continues even after the original trigger disappears.

How Dentists Treat Repeated Cheek Biting Near Back Teeth

Professional inner cheek bite treatment often focuses on reducing the chance of soft tissue getting trapped between the teeth during everyday activities like chewing or speaking. Depending on the diagnosis, treatment may involve small adjustments rather than major procedures.

For example, your dentist may:

• smooth sharp edges on restorations or enamel surfaces
• adjust how upper and lower teeth meet when you bite
• evaluate whether wisdom teeth are shifting your bite position
• recommend a custom night guard if grinding is contributing to the problem

These types of targeted corrections are especially helpful when patients notice they keep biting cheek tissue in the same location repeatedly.

Practical Daily Adjustments That Reduce Repeat Cheek Biting

Even small behavior changes can make a noticeable difference while the cheek heals. Patients who frequently keep biting inside of cheek tissue during meals often benefit from slowing their chewing pace and becoming more aware of how their back teeth meet.

Helpful adjustments include:

• chewing evenly on both sides of the mouth
• avoiding multitasking while eating
• choosing softer foods until irritation improves
• staying hydrated to support oral tissue recovery

These strategies reduce mechanical pressure on the injured area and support healing between dental visits.
