Cavities and Fillings

Cavities, the little consequence we get from not brushing and flossing properly or as often as we should. Cavities are probably one of the most common issues to happen to pretty much everyone. 


But what are cavities? 

Cavities happen when acidity from the food we eat (and don’t brush away after) eats away at the enamel of our teeth. As the enamel is weakened, it exposes the layers of the teeth below. This is when a cavity becomes painful and needs to be filled.  


How are cavities treated or filled?

The way cavities are usually treated is with dental fillings. Getting a cavity filled can take on average about an hour of time and your dentist can perform this in clinic. Before you cavity is filled, your dentist will numb your teeth, gum and surrounding area to make it as comfortable as possible. They then will drill out the decay and fill it with the dental filling. 


What are fillings made of? 

There are a variety of fillings available, your dentist will go over your options to ensure you get the best filling for your lifestyle, budget and appearance. 


  • Gold Fillings: Made in a laboratory and then cemented into place. Gold inlays are well handed by gum tissue and have a long life (about 20 years). This is the most expensive choice and requires multiple visits

  • Silver Fillings:  Are pretty resistant and a more affordable option. Although their dark colour is noticeable and are more so used in not visible areas of the mouth.

  • Composite (plastic) resins:  These resins are matched to the colour of your teeth and used in areas where a natural appearance is wanted. Composite resin is not recommended for large fillings as they may chip or wear over time. They last for up to 10 years.

  • Porcelain fillings: Are produced in a lab and then bonded to the tooth, they are matched to the colour of the tooth and stain resistant.
