Does your breath smell bad? Do you often have toothache? Chances are you have dental cavities. Cavities or caries are caused because of tooth decay. You can prevent cavities by regularly brushing your teeth. In case you have shallow cavities, your dentist will reverse them by treating with substances known as fluoride or calcium. Both these substances help in making enamel resistant to cavities. If the cavity is too large it has to be restored. However if it is small, your dentist will restore it by filling it. If it is irreparable, then your tooth has to be extracted. If the cavity has extended to the center of the tooth and has infected your nerve, the dentist will perform root canal treatment.
In this the nerves and blood vessels are removed. The central hollow portion of the tooth is filled with a filling material and a capping or crown is fitted over it which can be made of tooth colour. When a cavity is detected in the early stages it is less painful and the treatment costs less. Starch and sugar in the food that we eat are converted to acid by the various bacteria present in the mouth. This helps in tooth decay and forms cavities.
