These cosmetic dental covers provide a simple solution for enhancing your smile. They allow for freedom while smiling, drinking, or smoking without causing mouth discomfort.

This safe cosmetic solution hides tooth loss, crookedness, stains, and broken teeth, and can be fitted over crowns, veneers, partials, and bonding. It is a great alternative to expensive braces and is designed to look like a natural set of teeth with a wide selection of shades available. How To Use: Put the teeth in a cup of hot (almost boiling) water for one minute to make them flexible and ready for customization. Using a mirror, firmly attach them to your existing teeth. Press them firmly against the teeth and gently press the impression material behind the real teeth with your thumb. After thirty seconds, gently loosen the teeth from the mouth and then cool them in a glass of cold water. The impression material turns white when hardened.
