Margin Decay

While it is true that a crown protects and strengthens a tooth, sometimes decay can start at the margin of a crown, where the tooth meets the crown. Early detection and treatment will protect the tooth and help prevent future problems.

Why decay can form next to a crown

Decay can form in the area where the crown meets the tooth structure. This happens because it is one of the toughest spots to keep free of plaque and bacteria that cause tooth decay. If the gum tissue has receded since the crown was placed, tooth structure along the gumline is now open, another area for plaque and bacteria to sit.

It is important to treat tooth decay as soon as possible. Once decay has become established, it can grow quickly. If the cavity penetrates the outer enamel layer of the tooth and reaches the softer dentin layer, bacteria can cause an infection in the pulp layer, which contains your tooth's nerves and blood vessels. The only way to treat the infection is by performing root canal therapy to remove the infected tissue.

Diagnosis and treatment

We begin by performing a thorough examination and discussing the best treatment for you.

Due to the crown obscuring the decay on radiographs, it is not easy to see how far the decay has advanced. Therefore, it is likely that we will need to replace the crown with a new one. There are several types of crowns, so we will talk with you about the best one for your situation.

Treatment will protect your tooth. By treating the decay as soon as possible, we can often prevent it from spreading and causing unnecessary damage to your tooth, and more complicated, extensive treatment.

  • Dr. Rehder is very professional, yet not too serious as he is doing your teeth. He makes it relaxing and is able to keep your mind away from his work (I have never liked going to the dentist, but Dr. Rehder makes the experience as close to pleasant as a dentist visit can be).
