At Parker and Pennington Dentistry, our goal is to provide the very best care for our patients that promotes the overall wellness of their oral health. One of the many ways we do this is to return your mouth back to full function after trauma or decay. When the outer layer of the tooth, also known as the enamel, experiences decay, we typically recommend a filling to remove the cavity. You might be surprised to learn that your tooth also has an interior. The interior of the tooth is called the pulp, and when it becomes infected, we recommend a root canal.
