Gone are the days of having only one choice of filling material. For many years, amalgam had been the gold standard in restorative material. With advances in modern dental materials and techniques, we are finding more ways to create a more pleasing, natural looking smile with simpler and more cost-effective methods.
Today, more patients ask us for white fillings because they want their teeth to look natural when they laugh, talk and smile without the appearance of gray/ dark coloured fillings.
White fillings, also called composite fillings, are made from tooth-coloured resin compounds that restore the natural appearance of a decayed or previously filled tooth. A composite filling usually requires only one visit, during which the tooth is prepared and restored. An advantage of composite fillings over other dental restorations is that they require less of the healthy part of a tooth to be removed to hold the filling in place. This is due to the strength of composite materials’ ability to bond to teeth.
Composites are preferable for obvious cosmetic reasons but if the decayed area is large or is subject to heavy chewing pressure, we may recommend another type of material or restoration such as a crown.
White fillings, like other dental materials, may require periodic replacement. If not kept clean with daily brushing and flossing, the bonded adhesive layer of the filling may de-bond creating a microscopic gap for bacteria can re-infect the tooth between the filling and the enamel and eventually may cause decay. It is therefore, very important to see your dentist for regular dental check-ups because they allow us to detect a problem in the early stage with periodic X-rays.
