Less tooth structure is removed when preparing the tooth for a composite filling. This reduces the chance of irritating the nerve when repairing deeper cavities. Once the tooth has been cleaned and prepared, a bonding material is placed at the base of the preparation site. The resin material is then placed in layers, and a special light is used to harden each layer. This process takes a bit more time than other filling materials.
White fillings tend to have fewer sensitivity issues after placement, as compared to metal ones. While some composite fillings can be initially sensitive to hot and cold, this will diminish over a short period of time. Sometimes, the filling may be high, which causes a sharp pain when chewing. If this is the case, a quick trip to the dentist for a bite adjustment will fix the problem. People with a lot of silver fillings may also request that they be replaced with composite ones. This will dramatically change the patient’s smile, giving them more confidence. A consultation with the dentist can determine whether or not your fillings can be easily replaced.
