A dental filling repairs the damage caused by tooth decay or fracture. It restores the natural appearance of a decayed or previously filled tooth. Dental fillings today are tooth-coloured, which blend very well to tooth enamel and are able to bond to the remaining tooth structure.
Composite fillings are the most popular fillings today. They are natural-looking and made from composite resin. Composite fillings begin soft and they are hand-shaped during the filling process. A blue light is then used to cure the composite to harden it. Composite fillings are very durable and bond well to tooth enamel.
Sometimes our molar teeth have deep pits and fissures making it hard for the bristles of our toothbrush to clean, resulting in a breeding ground for bacteria to cause decay or cavities. Fissure seals are dental sealants used to fill the pits and fissures to act as a barrier against plaque, bacteria, and food particles.
Amalgam fillings, or more commonly known as silver fillings, were the most popular fillings many years ago. However they have fallen out of favour in recent years. Amalgam fillings are a mix of metal alloys, can contain traces of mercury and are dark in colour, which has been viewed unfavourably. Many people tend to replace these silver fillings with tooth-coloured filling.
