Hello, Any type of tissue change considered abnormal may be monitored and considered at a higher risk for a possible cancerous condition developing in the future. I recommend that you consider visiting an oral surgeon to evaluate the tissue since you report this as a reoccurring condition. Follow good daily oral hygiene. Avoid all irritants such as smoking and alcohol. Maintain your routine dental exams on a regular basis. Monitor for any changes and visit your dentist as soon as possible if you have any concerns. Early diagnosis is very important to Successful treatment if necessary. Your dentist has not recommended any medications or additional testing such as a biopsy from your description. I do not think there is any immediate concern other than careful monitoring. To put your mind at ease, plan a visit to the oral surgeon for a second opinion. Thank you for your inquiry. I am glad to answer questions if you provide additional information.
