Cheek biting can be accidental or caused by misaligned teeth, TMJ disorders, stress, or body-focused repetitive behaviors. Our family orthodontists in Clover, SC, can identify the root cause and recommend the right treatment to help stop the habit.
Do you find yourself biting the inside of your cheek often? It can be uncomfortable and frustrating, especially when it happens repeatedly.
The good news is that cheek biting usually has an identifiable cause. Understanding the root cause makes it much easier to find the right treatment. Our experienced orthodontists in Clover, near York, Smyrna, Kings Mountain, and Gastonia, NC, Dr. Wenderoth and Dr. Coombs, can help identify the exact cause of your cheek biting and create a personalized treatment plan to stop the habit for good.
Sometimes, cheek biting happens simply because you’re distracted while eating. When your attention is focused on something else, it’s easier to accidentally bite the inside of your cheek.
This type of accidental cheek biting often happens when:
After the first bite, the inside of your cheek may swell slightly. The swollen tissue can protrude more than usual, making it easier to bite again and continue the cycle.
Accidental cheek biting usually causes minor problems, but it can still lead to irritation inside the mouth. The most common issue is injury to the inner cheek, which may cause canker sores or mouth ulcers that make eating and speaking uncomfortable.
Cheek biting can also make it difficult to eat hot, spicy, or crunchy foods because they irritate the affected area. While these injuries typically heal on their own, the process can take time.
The tissue inside the cheek may thicken if cheek biting occurs frequently. This condition, known as Frictional keratosis, creates rough or white patches that can increase the risk of biting the cheek again.
Cheek biting usually happens for two main reasons: dental issues or habitual behaviors.
Dental causes include:
Psychological causes include:
Chronic cheek biting can sometimes lead to complications.
Open sores from cheek biting may allow bacteria to enter the tissue, leading to infection and inflammation that can require treatment.
When cheek biting is linked to TMJ disorder, it may create a cycle in which jaw inflammation leads to more biting, which then worsens the inflammation. Over time, this can contribute to jaw pain, headaches, limited jaw movement, and long-term joint problems.
If cheek biting is related to body-focused repetitive behaviors (BFRBs), it may also cause emotional distress, such as anxiety or feelings of shame.
After identifying the cause, the next step is to discover how to stop cheek biting.
If you frequently bite your cheek, our orthodontists in Clover may recommend a mouth guard to protect it, regardless of the underlying cause. For issues like TMJ disorder or habitual cheek biting, wearing a mouth guard prevents further injury while the tissue heals.
Our braces or Invisalign treatments in Clover can straighten misaligned teeth that lead to cheek biting and protect your smile.
Relaxation techniques like deep breathing, meditation, regular exercise, or therapy can help reduce the urge to bite. Chewing sugar-free gum can also keep your mouth occupied during stressful moments.
If cheek biting becomes a regular problem, Clover Orthodontics can help. Our orthodontists in Clover will examine your teeth and jaw to find the underlying cause—whether it’s misalignment, TMJ, or a habit.
From there, we’ll suggest the right treatment, such as braces, Invisalign, a custom mouth guard, or stress-management techniques, to stop cheek biting and protect your smile.
