Oral Mucosal Scarring: Causes and Treatment Options - Otolaryngology

Understanding oral mucosal scarring is crucial for managing discomfort and preventing further complications. Based on your description, it seems that the irritation from your second molar has led to the formation of scar tissue on the oral mucosa. This is not uncommon, especially when teeth are misaligned or protruding, causing chronic friction against the soft tissues of the mouth.

1. Will the scar tissue heal on its own?
Scar tissue in the oral cavity can sometimes resolve on its own, especially if the source of irritation has been removed or minimized. In your case, since the dentist has already smoothed the protruding part of the molar, the friction against the mucosa should decrease, allowing the tissue to heal. However, the healing process can vary from person to person. The scar tissue may not completely disappear, but it can become less prominent over time. If the area continues to be irritated or if you experience pain, it is advisable to follow up with your dentist or an oral specialist.

2. Does the molar need to be extracted?
Extraction of the molar is generally considered a last resort. If the tooth is functional and not causing significant pain or other complications, it may not be necessary to remove it. Your dentist's assessment is crucial here. If the tooth's alignment can be corrected through orthodontic treatment or if further adjustments can be made to prevent irritation, extraction might not be needed. However, if the tooth continues to cause issues or if there is a risk of further damage to the mucosa, extraction could be a viable option.

Regarding the treatment options mentioned by your dentist, such as carbon dioxide laser therapy or cryotherapy (liquid nitrogen), these are indeed valid methods for addressing persistent mucosal lesions or scar tissue.
- Carbon Dioxide Laser Therapy: This technique can precisely remove or reduce abnormal tissue while minimizing damage to surrounding areas. It can promote healing and reduce discomfort associated with scar tissue.

- Cryotherapy (Liquid Nitrogen): This method involves freezing the tissue, which can help in reducing the size of the scar and promoting healing. It is often used for various types of lesions in the oral cavity.

Both treatments can be effective, but the choice between them should be based on a thorough evaluation by your dentist or an oral surgeon. They will consider factors such as the size and location of the scar, your overall oral health, and any underlying conditions that may affect healing.

In summary, while the scar tissue may heal on its own, monitoring the area for any changes is essential. If you experience ongoing discomfort or if the situation does not improve, further intervention may be warranted. Always consult with your dental care provider for personalized advice and treatment options tailored to your specific situation.
