What is an Endodontist?

An Endodontist performs root canal procedures to save teeth.

Both Endodontists and your Family Dentist work closely with each other to ensure that you receive the best quality care. A visit to our conveniently located office can help in determining whether or not you’re tooth can be saved by having a root canal procedure done. In our modern, high tech office we provide care with expertise, compassion, and kindness.

The experts at Alliance Dental Specialists have been in the business since 1983. We are dedicated to our patients and we strive to make every visit comfortable and pain free. We have a wonderful team that works great together.
