Frequently biting the tongue and cheek while eating?


Hello, Doctor: For the past two years, I have been chewing food primarily with my left teeth, and I often bite my tongue or cheek, resulting in bleeding that lasts for several days of pain before healing.
I am now trying to use my right teeth to chew, which has slightly improved the situation.
I have previously visited a neurologist and underwent a brain CT scan, which the doctor said was normal, and I was advised to see a dentist or an ENT specialist.
Could you please explain what might be causing these symptoms and whether medical treatment or correction is necessary? Thank you for your help!

Dear Eric,
Hello.
Frequently biting your tongue or cheek can be attributed to two main dental reasons, aside from issues related to the coordination of the motor nervous system.
The first reason is related to malocclusion between the upper and lower teeth.
When the upper and lower teeth come together in a "cusp to cusp" relationship, there is a lack of protective overlap between the cusps, which can lead to the buccal mucosa being drawn in and bitten, as well as the lingual muscles being drawn in and bitten.
The second reason is related to bruxism or clenching during sleep, which can cause the buccal mucosa or lingual muscles to be sucked into the interproximal spaces, leading to the formation of bite marks over time.
This can result in the development of hyperplastic tissue along the buccal mucosa and both sides of the tongue, making it easier to bite.
The treatment methods include correcting the alignment of the teeth to ensure proper occlusion, which will protect the buccal mucosa and the sides of the tongue.
For bruxism or clenching, the use of an occlusal splint is recommended.
Wishing you peace and health.
Sincerely,
Dr.

More Info


Frequent biting of the tongue and cheeks while eating can be a distressing and painful experience. This issue, which you have been facing for the past two years, can stem from various causes, and understanding these can help in finding effective solutions.


Possible Causes
1. Anatomical Factors: Sometimes, the shape and alignment of your teeth and jaws can predispose you to accidentally biting your tongue or cheeks. If your teeth are misaligned (malocclusion), it can lead to an increased risk of biting soft tissues during chewing.

2. Nerve and Muscle Control: Issues with the neuromuscular control of the jaw can lead to unintentional biting. If the muscles that control chewing are not functioning properly, it may result in a lack of coordination, causing you to bite your tongue or cheeks.

3. Stress and Anxiety: Psychological factors such as stress and anxiety can lead to increased muscle tension and involuntary movements, including clenching or grinding your teeth (bruxism). This can increase the likelihood of biting your tongue or cheeks.

4. Sleep Deprivation: Poor sleep quality can affect your cognitive functions and motor skills, potentially leading to a lack of awareness while eating, which may result in accidental bites.

5. Eating Habits: Eating too quickly or while distracted can increase the chances of biting your tongue or cheeks. If you are in a hurry or multitasking, you may not be as mindful of your chewing.

6. Medical Conditions: Certain medical conditions, such as epilepsy or other neurological disorders, can lead to involuntary movements that may cause you to bite your tongue or cheeks. However, since you have already undergone a CT scan and it was deemed normal, this may be less likely in your case.


Solutions and Recommendations
1. Dental Evaluation: Since you have already been advised to see a dentist, this is a crucial step. A dentist can assess your bite and alignment, and may recommend orthodontic treatment or dental appliances to help prevent accidental biting.

2. Mindful Eating: Practice eating slowly and mindfully. Focus on your food and avoid distractions such as watching TV or using your phone while eating. This can help you be more aware of your chewing and reduce the likelihood of biting.

3. Stress Management: If stress or anxiety is a contributing factor, consider incorporating stress-reduction techniques into your routine. This could include mindfulness meditation, yoga, or other relaxation techniques.

4. Jaw Exercises: Consult with a physical therapist or a dentist who specializes in temporomandibular joint (TMJ) disorders. They can provide exercises to improve muscle control and coordination in your jaw.

5. Avoiding Certain Foods: If you notice that certain foods are more likely to cause you to bite your tongue or cheeks, consider avoiding them or modifying how you eat them (e.g., cutting them into smaller pieces).

6. Regular Check-ups: Continue to monitor your symptoms and maintain regular check-ups with your healthcare providers. If the problem persists or worsens, further evaluation may be necessary.

In conclusion, while frequent tongue and cheek biting can be a frustrating issue, understanding the underlying causes can help you find effective solutions. By addressing potential anatomical, psychological, and behavioral factors, you can work towards reducing the frequency of these painful incidents. If the problem continues, seeking further medical advice is essential to ensure that there are no underlying conditions that need to be addressed.
