In routine dental examination, it’s found that 90 to 95% of adults have cavity affecting permanent teeth. A cavity can impact the look of your smile and the function of affected teeth and if not addressed, extends deeper towards nerve giving rise to toothache.
A filling restores a tooth damaged by decay back to its normal form and function, and prevents further decay of the tooth.
Fillings vary in complexity and material. After removal of cavity, direct fillings are placed “directly” in a cavity, wherein indirect fillings, an impression of the tooth is taken and a custom filling is fabricated to fit in prepared tooth.
A number of factors considered while choosing particular type of filling material includes the symptoms associated with cavitied tooth, extent of the cavity and remaining healthy tooth structure, location of cavity on visible teeth, allergies to certain dental materials and the cost. We suggest a tooth restoration considering above factors to make the best choice for your mouth.
Fortunately, there are more types of fillings for teeth today than ever before.
Composite Fillings – A composite resin is made from a mixture of resins and fine glass particles and the filling matches the colour of the tooth. Thus, composite fillings are used most often on front teeth or the visible parts of the tooth. Composite fillings bond directly to the tooth, reducing the drilling needed like amalgam fillings.
Ceramic Fillings – Ceramic fillings are indirect way to restore a tooth. Since the restorations are tooth coloured, they look natural than other options. Ceramic Inlay or Ceramic Onlay are recommended for moderate cavity restorations. Ceramic fillings are more resistant to staining.
Glass Ionomer – Glass Ionomer fillings are made from acrylic and fluoroaluminosilicate, a component of glass. This type of filling is often used in small cavities or cavities that extends below the gum. It is also used for filling baby teeth.
Amalgam Fillings – Amalgam fillings are made from a mixture of metals including mercury and silver. Amalgam fillings are very strong, most often used for fillings in the back teeth and usually last for many years.
Gold Fillings – Gold fillings are made from gold alloy which is extremely durable. This type of filling lasts longer than any other type. Gold fillings do not match the natural color of your teeth and are expensive.
