Cavities happen, but metal fillings don’t have to. Even with the best dental hygiene routine, you may find yourself with tooth decay. If you do, Sierra Smiles Tahoe will treat the cavity with a white filling. The filling’s composite material protects against additional damage and tooth sensitivity by bonding to your existing tooth. The resilient composite material matches closely with your natural teeth, so the filling is barely noticeable. All anyone will see is your smile.
