If a small amount of food debris is left in your teeth, (which usually happens when one misses night brushing/or is careless with it) the bacteria which are present in the mouth react with the food. As a result, acid is produced. This acid starts dissolving the tooth leading to decay/cavity/_caries or a hole in the tooth.
IT IS BEST TO GET THE TOOTH CHECKED AT THIS STAGE, as unfortunately once a cavity starts, it does not stop, even if you brush your teeth regularly twice a day. The cavity keeps getting deeper till it reaches the second layer, ie dentine, and finally the third layer, ie nerve/ pulp leading to the need for a root canal.
A visit to the Dentist once the cavity starts, is remedied by a filling which takes a short time. This could be a silver or a white tooth coloured material known as cosmetic or composite filling.
We at Smile Delhi, use a tooth coloured composite material from USA /Germany/ Switzerland.
- The composites are preferred over silver as they match the tooth.
- Are mercury free.
- The amount of tooth we have to grind is much less ( compared to silver amalgams) as this material bonds chemically to the tooth. In silver amalgams the amount of tooth structure we have to grind is much more as it sets mechanically, so we have to create a retention form in the tooth, which means grinding off more tooth structure.
