Taking care of your teeth
You pride yourself on how well you take care of your teeth. You brush and floss every day, and you see your dentist for regular cleanings. You haven't had a cavity in years.
But at your last visit, your dentist said that the gum tissue around a couple of your teeth had receded. Sure enough, when the dental hygienist gave you a mirror, you could see what your dentist was talking about. The pink tissue above your eyeteeth (canine teeth) was noticeably higher than that above surrounding teeth.
