Teeth whitening

Types of teeth discolorations or staining

1. Extrinsic- Improper brushing or intake of certain beverages like tea / coffee can cause stains to accumulate on the surface of teeth. Over time these stains calcify and become yellow colored deposits. Professional cleaning or scaling can help get rid of these stains and deposits.
2. Intrinsic – There are certain discolorations which are internal in nature and cannot be helped with simple cleaning. In such cases teeth whitening is a good, effective and safe option.
