Dr.Armstrong and staff have created such a nice and calming environment. Honestly look forward to my appointments. As for Dental work, they do an excellent job. I had my molars removed recently and experienced very little pain the days after. To cap it off - they give the best goodie bags each appointment!

First visit was great with great staff, friendly and professional. My second visit was more in depth and I was very nervous about some minor surgery that had to be performed! It was awesome! I was so nervous, but Dr. Armstrong, his assistant and Munford (office dog/pet) made me at feel ease and pain free throughout the entire procedure!

Featured Dental Procedures

Porcelain Veneers

Porcelain veneers are a popular, natural-looking solution for a variety of dental imperfections, including stains, gaps, chips, and slight misalignment. The Mint Dental in Chattanooga, TN, performs hundreds of veneer procedures a year. We coordinate with the best ceramists in the nation to craft custom veneers from the highest quality materials. Using high-end digital scanners and the latest equipment, we ensure every detail is perfect to create the smile of your dreams. 

Dental Implants

Missing teeth can affect your confidence as well as your dental health. When the root structure of a tooth is no longer present, the body's natural reaction is for the tissue of your jawbone to begin to recede. As this occurs, the surrounding teeth begin to shift. This can lead to your face having a sunken appearance, causing you to look older than you are. Dental implants replace lost tooth roots, which provides the stimulation necessary to stop jawbone atrophy after tooth loss. These stable, long-lasting devices also keep crowns, bridges, and dentures firmly in place at all times.

Cosmetic Dentistry

Our cosmetic dentistry office serving greater Chattanooga provides a wide range of procedures that combine state-of-the-art technology and artistry to make your smile unforgettable. Cosmetic procedures can address stained or discolored teeth, chips or cracks, gaps, and crooked teeth. These issues obviously affect the appearance of your smile, but they also affect the way it functions. Dr. Armstrong is a dentist who can improve your bite and help you achieve the smile of your dreams with teeth whitening, porcelain veneers, Invisalign®, and other treatments.

Sedation Dentistry

Our Chattanooga, TN, office caters to anxious patients who hesitate to schedule treatment due to a fear of the dentist's office. We understand that dental phobia is a very real problem and want to help. To ensure your comfort and relation, Dr. Armstrong can provide different methods of sedation dentistry. For light sedation, we can administer nitrous oxide, which is safe for children and adults. For more severe cases of anxiety, we offer oral conscious sedation and IV sedation. Our gentle care can ease your fears and allow you to receive the care you need.

Transform Your Smile and Confidence With Custom Porcelain Veneers

In some cases, whitening alone cannot give you the harmonious, bright smile that you want. Our dentist provided durable, natural-looking porcelain veneers that transformed the appearance of this patient's smile and improved his overall confidence.

Are You Ready To Create Your Dream Smile?

Dr. Armstrong overs a wide variety of cosmetic procedures to transform lackluster teeth into a stunning movie-star smile. Oftentimes we combine multiple techniques in a custom treatment known as a smile makeover. When you come to our Chattanooga, TN, office, we can discuss your options and help you develop a plan tailored to your unique goals.

Experiencing a Dental Emergency? We Can Help.

Dental emergencies can cause anxiety, uncertainty, and in many cases, serious discomfort. If you have a problem that just can't wait, please give our Chattanooga dentist's office a call. We will work you into our schedule as soon as possible to get you the help you need.

I was very anxious about getting my wisdom teeth removed and had put it off far too long, but the staff put me right at ease. Before the procedure honestly felt kinda like being at a spa! I have felt minimal pain and have had minimal swelling. I will be going back for all future dental needs and would recommend this place to anyone

From when you walk in the door to leaving you couldn’t feel more comfortable, and you feel it’s more of wellness visit than a normal mandatory visit. Compared to my last dentist I felt I was in a time warp with all of the use dated high tech dental equipment. IT WAS EASILY THE BEST DENTAL EXPERIENCE OF MY LIFE.
