Dental crowns are protective tooth coverings used in restorative dentistry. Crowns are often applied in conjunction with other procedures. There are several reasons a patient might require a dental crown. Here are four conditions that can be treated with a dental crown procedure:
1. Your dental filling keeps falling out.
Cavities are caused by tooth decay. Tooth decay can degrade the enamel of your tooth. Dentists can treat cavities by drilling away the decayed tooth matter. The drilled area is then cleaned and filled with a dental filling. Dental fillings are usually made from amalgam or resin. Fillings are meant to last. Unfortunately, sometimes fillings fall out. A filling may fall out because it was improperly sealed. It may also fall out because it's simply too large.
If your dental filling continues to fall out, an alternative approach may be required. Your dentist may recommend a dental crown. A dental crown will protect your tooth from decay. It can save you from having to constantly return to the dentist to repair lost fillings on stubborn teeth.
2. You have an infected tooth.
Teeth can sometimes become infected. Typically, this happens when decay enters through your tooth enamel. Severe tooth decay can allow bacteria to penetrate the pulp of your tooth. When this happens, an infection can result. Antibiotics can temporarily clear up an infection, but root canal therapy is required to prevent the infection from returning. During root canal therapy, a dentist will remove the pulp and roots of your tooth. They will fill the remaining root canals with cement, then cover your tooth with a dental crown to protect it.
3. Your tooth is cracked.
Teeth are quite strong, but they are not invincible. Teeth can be cracked by excessive force. Biting down on a bone or hard candy can damage your tooth. Teeth can also be injured in a fall or through contact sports. Cracked teeth can often be salvaged, but they may require extra support. A dental crown will prevent further damage to your injured tooth. It can also restore your smile and prevent bacteria from getting into your tooth.
4. Your tooth is misshapen.
Teeth grow in all shapes and sizes. As long as your teeth are healthy and don't cause you pain, it doesn't matter what they look like. Still, some people are bothered by the appearance of an uneven smile. Dental crowns can be used for cosmetic purposes. If one of your teeth is unusually shaped, a dental crown can give you a more even, beautiful smile.
