Q: Why Do Mouth Sores Keep Recurring? Healing and Prevention

Hello： If you only notice the biting injuries upon waking up, it may be necessary to rule out the possibility of nocturnal bruxism. <br>It is recommended to initially use a soft occlusal splint to separate the teeth from the delicate mucosa, allowing the injured area to heal. <br

Repeatedly biting the same area?

Hello Doctor: Two weeks ago, I bit my mouth and developed an ulcer.
Last week, just as it was healing, I accidentally bit the same spot again.
After another week (yesterday), a blister formed on the wound.
I did not pop it, but it had burst by the time I woke up this morning.
Currently, the wound does not hurt, but it appears white.
I would like to ask why a blister formed during the healing process.
If I keep biting the same area, will it prevent the wound from healing quickly and potentially lead to complications? Thank you.
🙏🙏

It is recommended to initially use a soft occlusal splint to separate the teeth from the delicate mucosa, allowing the injured area to heal.
The presence of blisters on the injured lip may indicate damage to the minor salivary glands, leading to the rupture of mucus and blockage.
If the swelling is significant, it is highly likely to be a mucous cyst, which requires surgical removal by a physician.

More Info

Mouth sores, also known as oral ulcers or canker sores, can be a frustrating and painful experience for many individuals. The recurrence of these sores, particularly in the same area, can be attributed to several factors, including mechanical trauma, underlying health conditions, and lifestyle choices.
When you bite your cheek or tongue, it can lead to an ulcer. If the area is repeatedly traumatized, as in your case, it can hinder the healing process. The body’s natural response to injury includes inflammation and the formation of new tissue, but repeated trauma can disrupt this process. This is why you may notice that the sore does not heal properly and may even develop a blister or water-filled bump. The blister forms as a protective mechanism, allowing the underlying tissue to heal while providing a barrier against further irritation. However, if the blister bursts, it can expose the sensitive tissue underneath, leading to a white appearance as the area begins to heal.

In terms of healing, oral ulcers typically take about 1-2 weeks to heal, depending on their size and location. However, if you continue to irritate the area by biting it, the healing process can be prolonged. This can lead to a cycle of repeated trauma and healing, which may increase the risk of secondary infections or other complications.
Additionally, certain systemic conditions can contribute to the recurrence of mouth sores. For instance, nutritional deficiencies (such as vitamin B12, folate, or iron), autoimmune disorders, and stress can all play a role in the development of oral ulcers. If you find that your mouth sores are frequent and persistent, it may be worth consulting with a healthcare professional to rule out any underlying conditions.

To prevent the recurrence of mouth sores, consider the following strategies:
1. Avoidance of Trauma: Be mindful while eating and avoid hard or sharp foods that may cause injury to the oral mucosa. If you have a habit of biting your cheeks or tongue, try to identify triggers and work on reducing this behavior.

2. Oral Hygiene: Maintain good oral hygiene by brushing and flossing regularly. This helps to prevent infections that could exacerbate the condition.

3. Dietary Adjustments: Ensure that your diet is rich in essential vitamins and minerals. If you suspect a deficiency, consider discussing supplementation with your healthcare provider.

4. Stress Management: Since stress can exacerbate oral health issues, incorporating stress-reducing techniques such as mindfulness, meditation, or exercise may be beneficial.

5. Topical Treatments: Over-the-counter topical treatments can help alleviate pain and promote healing. Products containing benzocaine or other numbing agents can provide temporary relief.

6. Consultation with Professionals: If mouth sores persist or worsen, it is advisable to consult with a dentist or an oral health specialist. They can provide a thorough examination and may recommend treatments such as corticosteroids or other medications if necessary.

In summary, the recurrence of mouth sores can be attributed to mechanical trauma, underlying health issues, and lifestyle factors. By taking proactive measures to prevent trauma and maintain overall oral health, you can reduce the frequency and severity of these painful sores. If the problem persists, seeking professional advice is essential to ensure proper diagnosis and treatment.
