White Fillings

White fillings are tooth-colored materials, made from a mixture plastic and glass, used to fill decayed teeth. These fillings are also used for cosmetic improvements of the smile by changing the colour of the teeth or reshaping disfigured teeth.

The dentist first cleans your decayed portion of the teeth using a dental drill or a similar device. After clearing all bacteria, your dentist shapes your teeth and applies an acid gel / liquid to roughen the tooth surface. He then applies a thin layer of liquid bonding agent (this agent helps in bonding white filling material to the tooth structure), before finally covering your cavities with white fillings, and hardening the fillings using a special light and polishing them with various discs and drills.

It is a tooth-coloured filling. It blends with the natural tooth and is hard to spot, so the aesthetic improvement is the main advantage of this material. Also, placing of a white filling requires less removal of the healthy tooth tissue as compared silver filling. Finally, they bond to the tooth structure and strengthen teeth weakened by decay, unlike silver fillings.

Placing a white filling is a highly sensitive procedure that requires the skill and expertise of the clinician. The strength of the white filling material is also not as good as the silver material, so it isn’t the preferred material for filling badly broken teeth. Over a period of time, filling may become discoloured due to pigments in food, wine, coffee and tobacco. Excessive biting and bruxism cause the filling to crack or even break

Amalgam (silver fillings) and inlays, onlays or full crowns.

Many patients these days choose white-coloured or tooth-coloured composite fillings, as they bond to the tooth structure and strengthen a tooth weakened by decay. However, White fillings cannot be used in every situation, while Silver fillings, Inlays, Onlays or Full Crowns can be used with great success.

White fillings are 50% more expensive when compared to silver fillings, as the techniques used to place white fillings are more complicated and the treatment procedure also requires more time. Despite the cost, many patients prefer white fillings because they are tooth-coloured, thus nearly invisible.
