Jaw Muscle Issues: Why Do I Keep Getting Mouth Sores? - Dentistry

Mouth sores, particularly those that occur in the area where the gums connect to the teeth, can be quite bothersome and may arise from various underlying issues. Based on your description, it seems that you have a history of oral trauma, particularly from biting the inside of your cheeks, which can lead to recurrent sores. However, the fact that you are now experiencing sores specifically at the junction of the gums and teeth suggests that there may be additional factors at play.

One potential cause for the recurrent sores in this area could be related to the function of the jaw muscles, particularly the masseter and temporalis muscles, which are responsible for chewing. If these muscles are overworked or strained—perhaps due to stress, grinding your teeth (bruxism), or even poor posture while working—this can lead to tension in the jaw and surrounding areas. This tension can manifest as soreness in the jaw and may contribute to the development of mouth sores, especially if you are inadvertently biting down harder or clenching your teeth.

Another factor to consider is the health of your oral environment. If you have any misaligned teeth or dental work that causes irritation to the gums, this could also lead to sores. Additionally, if you are experiencing any form of gum disease, such as gingivitis or periodontitis, this could contribute to inflammation and soreness in the gums, making them more susceptible to ulceration.

Stress is another significant factor that can lead to mouth sores. Stress can weaken the immune system, making you more prone to infections and sores. It can also lead to habits such as nail-biting or lip-biting, which can further exacerbate the problem.

Dietary factors may also play a role. A diet lacking in essential vitamins and minerals, particularly B vitamins, vitamin C, and zinc, can lead to a compromised mucosal barrier in the mouth, making it easier for sores to develop. Additionally, certain foods, particularly acidic or spicy foods, can irritate existing sores and make them more painful.

To address your concerns, it is advisable to take a multifaceted approach:
1. Oral Hygiene: Maintain excellent oral hygiene by brushing and flossing regularly. Consider using a soft-bristled toothbrush to minimize irritation to the gums.

2. Stress Management: Engage in stress-reducing activities such as yoga, meditation, or regular exercise. These practices can help alleviate muscle tension in the jaw and reduce the likelihood of teeth grinding.

3. Dietary Adjustments: Ensure you are consuming a balanced diet rich in vitamins and minerals. If you suspect deficiencies, consider consulting with a healthcare provider or nutritionist.

4. Dental Evaluation: It may be beneficial to visit a dentist for a thorough examination. They can check for any misalignments, gum disease, or other dental issues that may be contributing to your mouth sores.

5. Jaw Relaxation Techniques: Practice relaxation techniques for your jaw, such as gentle stretching or massaging the jaw muscles, to alleviate tension.

6. Avoid Irritants: If certain foods or habits seem to exacerbate your sores, try to avoid them until your mouth has healed.

If your mouth sores persist despite these measures, or if you notice any additional symptoms such as swelling, fever, or difficulty swallowing, it is crucial to seek further evaluation from a healthcare professional. They may recommend additional treatments or tests to rule out any underlying conditions that could be contributing to your symptoms.
