You need a tooth filling if you have dental cavities or dental decay. The accumulation of plaque and tartar on the teeth may lead to the formation of cavities and bacterial decay. If you don’t treat cavities with dental fillings, the bacteria will continue going deeper into your teeth and eventually reach the pulp chamber, necessitating a root canal or tooth extraction. A dental filling involves removing the decayed parts of your teeth and replacing them with dental filling material, thus preventing the infection from spreading further.
You may also need a tooth filling to protect the tooth after it has been damaged. If your tooth is chipped or cracked because of injuries or accidents, you may need a dental filling. The dentist can place a dental filling material on the chipped or cracked part of your tooth. The dental filling material protects the tooth and prevents the cavity from spreading. If you don’t get a tooth filling, bacteria may enter the damaged parts of your teeth and increase the risk of dental decay.
