Teeth Whitening

Unhappy with your off-white smile? Have you tried at-home dental treatments and still see the stains?

Professional teeth whitening is the best way to whiten your smile quickly and safely.

Dr. Damien Armstrong and his team of Chattanooga, TN, dental professionals can give you a whiter smile you'll be proud to show off.

What Is Teeth Whitening?

Teeth whitening is a common type of dentistry that can remove years of stains to create a whiter, brighter smile. There are several different types of whitening options, from whitening toothpaste and over-the-counter trays to professional in-office treatments. Although the low prices and accessibility of many over-the-counter whitening products can be tempting, the fact is that professional whitening is safer and far more effective.

Benefits of Teeth Whitening


Things we eat and drink daily like coffee, tea, or wine can have a lasting impact on the appearance of your smile. Having stained teeth can make you feel self-conscious and prevent you from smiling in front of anyone. Tooth whitening not only gives you whiter teeth, but it can boost your confidence and give you a smile you'll want people to notice.

Who Is a Good Candidate for Teeth Whitening?

Virtually anyone with all their permanent teeth who would like a brighter, more dazzling smile is a candidate for teeth whitening. And because our Opalescence® treatment achieves incredible results in a relatively short amount of time, it's a fantastic treatment for brides and grooms-to-be, or anyone who needs to look their best for an upcoming event. Reach out to our downtown dentist office in Chattanooga, TN, to see if teeth whitening is right for you.

The Beauty of Opalescence 

This is a form of whitening that uses a prescription-strength bleaching gel prescribed by your dentist. The gel consists of carbamide peroxide, which contains hydrogen peroxide and is a highly effective whitening solution. The gel and customized trays will be sent home with you to wear overnight. 

How Does the Opalescence Method Work?

Your journey to a brighter smile begins with a visit to our downtown Chattanooga office.

First, your dentist will take an impression of your bite that will be used to create a customized bleaching tray. This tray is designed to hold your prescription-strength carbamide peroxide whitening gel and apply it to your teeth, without letting any of the gel migrate to your gums.


These whitening gels are available in a variety of strengths, and your dentist will prescribe the strength that will best meet your needs. We even offer three different flavors (regular, mint, and melon) to make your experience as pleasant as possible. The gel is also available with potassium fluoride, which decreases tooth sensitivity, strengthens enamel, and helps prevent cavities. 


At night, after brushing and flossing, you will place a single dose of whitening gel into the customized mouthpiece, which you will wear while you sleep. You may see results after just one night of treatment. However, the full results are typically achieved after one week.

If you are looking for a great dental practice in Chattanooga, look no further! I typically avoid the dentist because I hate it so much. I finally decided to go and decided to check out River City Dentistry. Their location on Cowart St. is beautiful, super clean, and easy to find. The front desk staff is friendly and helpful...

I came in for a routine filling and I casually mentioned to Dr Armstrong about some staining on my front teeth. He willing said "I can take care of that for you" He took care of my teeth staining and I'm more confident in my healthy beautiful smile. Thank you Dr Armstrong!

Teeth whitening is not a permanent solution, but with proper care, you can make the effects of your treatment last a long time. Below are some things to avoid and ways you can prolong the results of your whitening treatment.


Quitting tobacco use is always advisable, and it is especially effective in keeping your teeth bright and healthy.

Coffee and Tea

If you drink coffee and tea, try and do so in a single session, rather than drinking coffee throughout the day, and brush when you're done.


If you drink red wine, don't run straight to your toothbrush afterward, because the acidic properties of wine temporarily weaken tooth enamel. Instead, try chasing your next glass with broccoli or cauliflower, which can gently scrub your teeth, or having a drink of seltzer, which can prevent red wine stains on your teeth.

Over-the-Counter Versus Professional Whitening

There are several options for over-the-counter whitening treatments, and your dentist will typically recommend the use of a whitening toothpaste after your professional whitening. However, some at-home whitening tools can be a risk to your oral health, like bleaching trays with too much hydrogen peroxide that can damage your enamel. Some people start these OTC treatments not knowing that they are actually allergic to the active ingredients. Other OTC products just don't provide the results you were hoping for. By seeing a dental professional, you can rest assured that you will get the whitening results you want quickly and safely. Let our Chattanooga team of dentistry professionals give you the white smile you've always wanted.
