First and foremost you should get scaling and polishing done. This will remove the unsightly stains and tartar deposits from your teeth. Then if you want a sparkling white set of teeth, you can undergo cosmetic teeth whitening or bleaching strictly under professional guidance . Your dentist will tell you about the various modalities of professional cosmetic teeth whitening procedures.

Visit dentist for scaling and polishing.  If still not satisfied go for teeth whitening procedures,  in clinics or home bleaching under the guidance of the dentist.  Side effects such as sensitivity of teeth may arise after bleaching procedures.
