Tooth Cavities and Fillings

The original shape and function of the teeth are restored with composite resin by filling the gap following the removal of tooth decay.

Decay is usually caused by a combination of a high-sugar diet, poor oral hygiene, or fewer mineralized teeth, and therefore making the teeth more fragile. The bacteria naturally present in our mouths cling to our teeth causing dental plaque. When dental plaque is not properly removed by brushing alone, the bacteria transform the sugars from food into acidity, which then attacks the tooth enamel. When tooth decay begins, the dentist removes the part of the affected tooth and places a composite resin filling (“white filling”) to restore its shape and function. The earlier the decay is detected, the smaller and longer-lasting the filling will be. When the decay reaches a more advanced stage, we must proceed with a root canal, crown, or CEREC, as the case may be. Large fillings tend to cause cracks and fractures over time. This is the reason why, at Sourire Concept, we urge you to visit your dentist regularly to prevent tooth decay.

Did you know? Silver fillings have long been used and are now replaced by white fillings. The silver filling is in fact a metal alloy composed of lead, silver and mercury, among other components. Composite resin fillings are now used instead. Without any metal components, they originate from nanotechnology and are known for their aesthetic beauty.



  1. Once the proper diagnosis is made, a second appointment for the procedure will be given.
  2. The decay creates a cavity within the tooth, attacking the enamel – at this stage, if the enamel is not perforated, the dentist may treat the decay with fluoride agents to avoid having to restore your tooth.
  3. When the decay reaches the dentine, your dentist must repair the tooth, meaning the decayed tooth material will be removed and filled with a composite resin (“white filling”). This  procedure only requires one appointment and is performed under local anaesthesia.
  4. The composite resin filling is custom-made for your tooth. It is then inserted into your tooth and adjusted accordingly and polished and shaped.
  5. Once duly placed, the filling is hardened by polymerization (blue light).

Advantages of Composite Resin Fillings

Composite resin fillings (white fillings):

  1. Do not contain any mercury, contrary to dental amalgam (“silver filling”)
  2. Is available in a multitude of shades to best match the color of your teeth and are custom-made to fit your teeth.
