Gentle, Metal-Free Root Canal Therapy Can Save Infected Teeth

Root canal therapy is an invaluable treatment because it can save infected teeth that would otherwise need to be extracted. While the procedure has a reputation for being unpleasant, our treatment is much gentler than most patients ever imagine it could be. During root canal treatment, Dr. Mike Glasmeier will remove the infected tissue, then fully restore the tooth with a custom-made dental crown. At First Impressions Family Dentistry in Old Hickory and Antioch, TN, we offer root canal therapy tailored specifically for patients with special needs. With our detail-oriented techniques, friendly demeanor, and a variety of sedation options, the treatment is designed to be quick and involve minimal stress.

We have done everything possible to make our root canal treatment a pleasant and relaxing experience. In addition to a fully accessible office with comfortable chairs, we offer dental sedation.

Why Would You Need a Root Canal?

Most often, we will recommend a root canal, or endodontic therapy, to repair infected teeth. Infection develops when bacteria enter the central chamber of a tooth, which contains soft pulp and nerve endings. The nerves travel all the way down the root canals. As an infection worsens, it will spread along the roots and could cause a variety of symptoms such as:

  • A toothache, especially an ache that worsens when biting down
  • Sensitivity to heat or cold
  • Small sores just below the tooth, known as abscesses
  • Chronic bad breath
  • Dark internal stains

Symptoms may not always be present, which is why routine exams are so important. Dr. Glasmeier will take x-rays and examine the tooth to be certain that a root canal is the best treatment. He may also recommend endodontic therapy to repair a tooth with a large crack.

What to Expect During the Procedure

After numbing the area and creating an access point, Dr. Glasmeier will clean out the inside of the infected tooth. Using extremely gentle methods, he will remove all the affected tissue. Simultaneously, he will reshape and enlarge both the central chamber and the root canals. If needed, he can use a topical medication to more thoroughly disinfect the area. Next, Dr. Glasmeier will fill the tooth and root canals with a soft, rubbery filling. He will then provide a temporary restoration, which will remain in place until your permanent crown is finished. At that time, you or your child will come in for a second appointment, and we will attach the crown. We only use all-porcelain crowns, which are both safer and more realistic than restorations that contain metal. 

Why Choose Us for Your Root Canal Treatment

Dr. Glasmeier and his team are an outstanding choice for endodontic therapy, especially for patients with special needs. We understand that this experience could be frightening, or that they might find it uncomfortable to sit in the dental chair for long periods of time. We have done everything possible to make our treatment a pleasant and relaxing experience. In addition to an accessible office with comfortable chairs, we offer dental sedation. Nitrous oxide, oral conscious sedation, or intravenous (IV) sedation may benefit those with anxiety.

Furthermore, as the father of special needs children, Dr. Glasmeier brings his own sense of compassion to every treatment. He talks to each one of his patients for as long as they need. During this time, he explains every step of the process, and he answers any questions they may have. Throughout the procedure itself, he can stop to explain various steps and put his patients’ minds at ease.
