Veneers are thin coverings that are placed over the visible part of the tooth. Veneers look and feel like natural teeth. They are used to improve the appearance of stained, chipped, cracked, and worn-down teeth. Dental Veneers can also be used to close gaps between teeth. Teeth can become worn down or stained from tobacco use, caffeine, and food. With just a few visits, veneers can provide a permanent fix to years of damage to your teeth.
