Maintaining veneers is similar to caring for your regular teeth. Following a good oral hygiene routine is essential to keeping your veneers and natural teeth healthy and free of decay. In addition to brushing and flossing daily and seeing your dentist for regular checkups, here are other important ways to maintain veneers: Do not chew on your nails or non-food objects, such as ice or pens. Do not use your teeth to open packages or undo knots Avoid hard, sticky foods, such as caramels, popcorn, taffy, nuts, and hard candies. Ask your dentist about a custom mouthguard  if you play contact sports. Do not clench or grind your teeth. If you grind your teeth at night, ask your dentist about a custom bite splint to wear.
