Lumineers are a brand of porcelain veneers that can change your overall smile by filling gaps and whitening your teeth. Lumineers are thin shells of porcelain that are bonded onto the front side of teeth. They are made stronger than most other brands of veneers, so they can be made thinner. Lumineers are a great solution to allow smile makeovers to be completed with no needles, shots, drilling or pain.
