Understanding Composite Fillings

When decay rots away enamel, the resulting space is called a cavity. Left untreated, the decay will cause extensive damage to the tooth, and potential root infection.

However, if the cavity is caught early, your dentist can treat it with a simple filling, typically in one appointment.

Your dentist will first apply a local anesthetic, then use a drill or laser to remove the decay.

A filling is then applied to prevent further decay, and decrease the possibility of tooth sensitivity.

The filling is applied in layers and hardened with a special light, the final layers being shaped and polished to restore the tooth’s appearance and function.

Nowadays, composite (plastic resin) is the most common filling material used over the silver amalgam used in the past.

Composite fillings are superior to that of the silver amalgam due to it traces of mercury.

Composite fillings are also less likely to result in tooth sensitivity and closely match the colour of the tooth making fillings nearly invisible.
