DEAR DR. ROACH: Providing that a person has good dental hygiene, what changes should a person expect to their mouths into their 70s, 80s and beyond? — K.Z.
ANSWER: Unfortunately, many seniors lose their teeth as they get older. Over a quarter of people over the age of 65 have no remaining teeth. It is clear that regular dental visits along with brushing and flossing help preserve your teeth. Smoking is a severe risk to teeth, and so is chewing tobacco. Oral nicotine and vaping are risky but not quite as bad.
