Fillings

What are Fillings?

Modern dentistry has allowed us to combine beauty and strength when filling teeth. Restorations like fillings allow teeth to regain their original strength and appearance through the use of composite resins and other modern materials. Fillings (restorations) are used to replace tooth structure that has decayed. This decay is most often caused by cavities, which can be detected through direct observation or x-rays. Fillings are also used to repair fractured, broken, or severely worn teeth to restore functionality. In order to fill a tooth, the dentist will first prepare the area by removing any remaining decay and shaping the filling location. The next step is the addition of a composite-resin filling material which is cured (hardened) using a specialized heating lamp. The final step is to polish the filling to ensure that it adapts smoothly and organically to the natural shape of the tooth.

Fillings do not last forever so it is essential that you visit the dentist regularly for further examinations. Fillings can develop cracks or simply wear down due to chewing and regular wear and tear. Our dentists monitor the integrity of your fillings during regular exams and will recommend replacing a filling if a problem is detected.

Composite Fillings

Composite fillings are the most common and popular option. They are very aesthetic since they are available in natural white and cream shades, which match the colour of most teeth. They are also easily integrated into teeth. In cases where the cavity preparation becomes very large due to the level of decay, the dentist will recommend an inlay or an on-lay (partial crown), restorations designed to replace more tooth structure. Those restorations are made in our dental laboratory after the dentist has taken a customized impression of the preparation. The final placement of inlay or on-lay will be made in a second visit at the dental office if needed.

Amalgam Fillings

Dental amalgam is a mixture of metals that consists of liquid (elemental) mercury and a powdered alloy composed of silver, tin, and copper. Dental amalgam fillings are also known as “silver fillings” because of their silver-like appearance. The chemical properties of elemental mercury allow it bond with the silver/copper/tin alloy particles to form an amalgam.

Amalgam fillings are available upon request.
