+ Years In Services

Quality Dental Care, Close to Home!

We always encourage you to contact us with any comments, concerns, or questions. You are also welcome to request an office tour, and come meet our team before your first appointment. You will appreciate Dr. John and Dr. Joseph Barnhart and our friendly Vienna team for the care we provide to all of our patients, from infants to senior citizens. Give us a call and schedule an appointment or consultation- whether you need orthodontic care, a cosmetic procedure, smile restoration, or just a general cleaning. We also offer customized crowns, bridges, and dental veneers.

Barnhart Dental recommends that all of our patients schedule a preventive care exam at our dental practice once every six months, and of course: brush and floss your teeth at least twice every day. Just like your physical health, prevention is the best strategy when it comes to preserving or improving your oral health. Barnhart Dental offers convenient financing options, in addition to accepting most forms of insurance.

Friendly and experienced dentists, we’re here to serve you!

FAQs

Frequently Asked Dental Questions

Dr. John and Dr. Joseph Barnhart have practiced for decades, and have come across a fair number of questions from our patients. Our entire Barnhart Dental team works hard to ensure our patients understand and receive answers to all questions in relation to their oral health.

MORE FAQs

Are dental x-rays safe?

According to Dr. Joseph Barnhart, for any radiation to cause harmful effect it would have to exceed a certain threshold of intensity. While any form of radiation is a potential carcinogen, the radiation that dental patients are exposed to is in very small amounts, and are only directed to very specific sites of interest. This specificity, coupled with a very tiny exposure period, is what ensures that dental x-rays are widely considered to be safe diagnostic dental tools.

What is the best toothpaste to use?

Look out for the ADA Seal of Acceptance on any toothpaste before spending your money on it. The ADA seal of acceptance is a quality mark approval of the efficacy and safety profile of dental products that have been approved by the ADA Council on Scientific Affairs. Every ADA approved toothpaste contains fluoride, which helps prevent tooth decay. If your toothpaste has that seal, the brand name doesn’t matter, just pick your favorite flavor!

How can I enhance my smile?

With the advancements in dental procedures, there are several techniques at the disposal of the Barnhart Dental team to improve the health and appearance of your smile. We offer a variety of smile restoration procedures, including porcelain crowns, tooth whitening, implants, and veneers to just mention a few. Dr. Barnhart will advise on the best procedure to use to enhance your smile upon a comprehensive oral assessment.

Are dental amalgam fillings safe?

Dental amalgam fillings are safe for dental patients over six years of age. Both the FDA and The American Dental Association have commissioned studies and evaluated the safety profile of amalgams, and have allayed fears associated with these restorations. To date, no scientific study has demonstrated any causal relationship between amalgam fillings with any negative medical conditions.
