Martin Dentistry in Johnson City, TN

Martin Dentistry merged with Dr. Andy Armbrister’s Johnson City practice in 2018. Many of the staff have worked at this office for a dozen or more years. In addition to traditional dental services, we provide complex, full mouth reconstruction services. We also do same-day crowns, IV sedation, and root canals. And for patients needing crowns or dentures, we offer digital teeth scans. That means no more cold, uncomfortable impressions—and we get a more accurate picture of your teeth.

There’s a story behind every smile, and we would love to be a part of yours!

Johnson City Office FAQs

We take digital scans of your teeth, instead of traditional, uncomfortable impressions. This gives you a more pleasant dental experience, and it gives us a more accurate scan of your teeth. 

Full mouth reconstruction is the rebuilding of all the teeth in a patient’s mouth. This is a specialty of Dr. Armbister. If you have further questions about this service, please call our office at (423) 434-2421.

With same-day crowns, you can get your complete crown completed in one appointment. (No temporaries!) Dr. Arbister designs and creates your crown himself using a CEREK dental milling machine. To learn more, please call our office at (423) 434-2421.

Martin Dentistry offers three types of sedation dentistry: nitrous oxide, oral medication, and IV sedation. Before delivering any sedative, your dentist will analyze your medical history and take note of any current medications. To learn more, visit our sedation dentistry page.

Our caring dentists are professional dental practices dedicated to excellence in general, family and cosmetic dentistry, such as orthodontics, Invisalign, dental implants, same day crowns, root canals, regular cleanings and prevention and many others.
