What is the difference between laser whitening and custom mouthpieces?
Laser-whitening is done by a dentist who applies a 35% Hydrogen Peroxide solution on your teeth. Once this solution is applied, a light is held a couple of inches away from your teeth to speed up the chemical reaction of the Hydrogen Peroxide. The only benefit of doing laser whitening is that your teeth become white instantaneously. Although, this procedure is highly expensive and usually after a year, your teeth become slightly discolored again and develop new stains.
