HI I HAVE LOST QUITE A  FEW TEETH AND IN THE RIGHT BOTTOM GUM IN THE BACK WHERE A TOOTH WAS EXTRACTED A FEW YEARS AGO THERE IS A LITTLE WHITE SPOT AND IT JUST FEELS LIKE A PIECE OF FOOD BUT I LOOK IN THE MIRROR AND THERE IS A WHITE SPOT I AM NOT SURE WHAT IT IS DO U HAVE ANY SUGGESTIONS
Thanks for your query, I have gone through your query. The white spot could be secondary to chronic irritation by the opposing tooth or food or denture that result in frictional keratitis. Consult an oral physician and try to find out the cause and rectify it. Nothing to worry about it, it is harmless. I hope my answer will help you. Take care.
