Hi, Welcome to icliniq.com. Most often these types of lesions (attachment removed to protect patient identity) are from frictional keratosis which is a soft tissue that becomes tough and white due to continuous friction over time. If you were to go and see an oral surgeon for evaluation and possible biopsy they would likely look for sharp edges on your teeth in the area, smooth them down, and give it a few weeks. If everything looks the same in a few weeks, then they will likely monitor it every six months. It means they will take pictures now, then after six months, and again in six more months and compare them.
