Many of the things that dental and cosmetics professionals have said about reversing mouth damage, or preventing it, are largely intuitive. It's obvious that you can correct a deteriorating smile with good oral hygiene habits, by not using your teeth in ways in which they were not intended, and by consulting a dental or health professional.

Dr. King recommends that soda lovers drink soda, then a glass of water, and brush teeth 45 minutes later, since "if you brush right away after acidic drinks/foods, you actually can cause more damage to your teeth." She also recommends "wine wipes, which are small, portable wipes specifically designed to clean the surface of your teeth of wine residue."

Dr. Jarret L. Manning suggests flossing before you brush so you don't forget to incorporate flossing into your dental routine, while Dr. Lazarof suggests a mouth guard for night grinders. Taylor recommends a foundation primer to prevent foundation from settling into fine lines.

But in general, be smart about your smile.
