You want to restore your natural tooth shade or want to whiten your yellowish teeth, tooth whitening is the perfect option for you.
Restoration of the underlying, natural tooth shade is possible by removing the surface stains and calculus. This can be done by cleaning teeth through various oral hygiene methods. Calculus is difficult to remove without a professional clean.
In order to whiten the tooth shade, beaching is required. Techniques include bleaching pen,
bleaching strips, bleaching gel, and laser tooth whitening. Bleaching methods use carbamide peroxide or hydrogen peroxide. Increased sensitivity of teeth and irritation of the gums are some of the side effects of bleaching. Some people also develop an unhealthy obsession with whitening similar to body dismorphic disorder.
