I am 45 and just noticed a white patch behind my last molar. had both molar wisdom tooth pulled on that side many years ago. wondering if this is scar tissue or something more sinister.?

It is important to have any new or concerning changes in your mouth evaluated by a dentist or oral surgeon. While it is possible that the white patch you have noticed is scar tissue from your wisdom tooth extraction, it is also possible that it could be a sign of an underlying oral health issue such as gum disease or an infection.

I would recommend scheduling an appointment with your dentist as soon as possible so that they can properly examine the area and provide a diagnosis. They may recommend additional tests, such as an X-ray or biopsy, to determine the cause of the white patch and recommend the appropriate treatment.

In the meantime, here are some tips for maintaining good oral hygiene:

* Brush your teeth twice a day with a soft-bristled toothbrush and fluoride toothpaste.

* Floss your teeth daily to remove plaque and food particles from between your teeth.

* Use an antibacterial mouthwash to kill bacteria and freshen your breath.

* Avoid sugary foods and drinks, which can contribute to tooth decay and gum disease.

* See your dentist regularly for checkups and cleanings.
