What is a Filling?

A filling is a way to restore a tooth damaged by decay back to its normal function and shape. First the decayed tooth material has to be removed by cleansing the affected area. Once the caries has been cleaned out, the cavity is restored with a filling material.

By closing off spaces where bacteria can enter, a filling may also prevent further decay. Materials used historically for fillings include gold and amalgam (an alloy of mercury, silver, copper, tin and sometimes zinc). Now days we only offer composite resin (tooth-colored fillings), porcelain or zirconia (a white metal classified as a member of the titanium family) or glass ionomer fillings (used on baby teeth and ‘non-biting’ surfaces).

Which Type of Filling is Best?

No one type of filling is best for everyone. What’s right for you will be determined by the extent of the repair, whether you have allergies to certain materials, where in your mouth the filling is needed, and the cost.

Are the silver fillings harmful?

Research into the safety of dental amalgam has been carried out for over 100 years. So far, no reputable ‘controlled’ studies have found a connection between amalgam fillings and any medical problem.


If decay or a fracture has damaged a large portion of the tooth, a crown, (sometimes called cap), may be recommended. Decay that has reached the nerve may be treated in two ways: through root canal treatment (in which the damaged nerve is removed) or through a procedure called pulp capping (which attempts to keep the nerve alive).


Dental Bonding

Dental bonding is usually a cosmetic procedure in which a tooth-coloured resin material (a durable plastic composite filling) is applied and hardened with a special light, which ultimately “bonds” the material to the tooth to restore or improve a person’s smile.

In the past, bonding was a cost-effective alternative to crowns or veneers when trying to improve your smile. Recently it is becoming very popular, as the materials used are much stronger and better looking. Teeth bonding is also much less invasive compared to dental crowns or veneers, which results in less or no tooth has to be removed.

What is the difference between Bonding, Veneers and Crowns?

Bonding is made with resin – composite. It looks very good but is slightly inferior the porcelain material used for veneers or crowns.

Bonding is most of the times non invasive ( you do not remove any healthy part of the tooth), which results in being a reversible procedure ( you can remove the filling in the future, and your tooth will have no damage at all.

Veneers and crowns on the other hand, require a significant part of the tooth to be removed prior to placing them. If the tooth is already damaged, then a crown could be a better option.
