A cavity calls for your dentist to remove the decay and to fill in the tooth area that was removed in order to prevent further decay and strengthen the affected tooth. There have been lots of advances in modern dentistry that make this process much more comfortable and use materials that are safer and more esthetically pleasing.

SILVER FILLINGS
Earlier the trend was to have amalgam fillings (silver) or gold filling restorations. These fillings contain mercury which is poisonous to the body as well as the environment. Also the amalgam fillings are generally not as advantageous as composite fillings because they demand more of a tooth removal and are susceptible to corrosion.

COMPOSITE FILLINGS (Tooth-coloured)
Composite FillingsComposite resin dental fillings were created as an alternative to traditional metal dental fillings. Tooth fillings colored to look like a natural tooth are known as Composite Resin Dental Fillings and are made of a plastic dental resin combined with glass particles. These types of fillings are, durable and are way more natural looking than amalgam fillings.

If you have a cavity in a tooth or broken fillings or if your teeth are full of silver fillings you may want to ask your dentist about changing to composite dental fillings. Silver fillings can easily be removed and replaced with far more attractive colored fillings. Research shows that composite fillings actually strengthen your tooth and further protect it from decay.
