The Life-Changing Benefits of Orthodontics 

Boost Your Confidence

Your smile is often the first thing people notice about you, but crooked teeth can make daily interactions feel like a challenge. Orthodontics can help patients feel more confident about their appearance and increase their quality of life.

Choose from a Range of Options

Whether you are looking for orthodontics for yourself or your child, we have different treatment options for any need. Our dentists work with you to create a custom plan and help determine whether braces or Invisalign® is best for you.

Protect Your Oral Health

Orthodontics not only enhance your appearance, but also improve your oral health as well. Crooked teeth are difficult to clean, cause uncomfortable bite issues, and can even cause pain and stiffness in the jaw.

Save Money in the Long Run

By investing in orthodontics, you're investing in a healthier smile that pays itself off over and over. Addressing misalignment is key when it comes to reducing costly dental issues in the future.

What Issues Can Orthodontics Address?

If you have any of these dental issues, we encourage you to schedule a consultation at our office in downtown Chattanooga. Our dentist, Dr. Damien Armstrong, will conduct a thorough evaluation to determine the best orthodontic solution for you.

What Dental Issues Can Crooked Teeth Cause?

While patients typically turn to orthodontics for cosmetic purposes, treatment has a host of oral health benefits as well. The following issues can occur as a result of crooked teeth, which makes achieving a straighter smile that much more important:


If you have crowded or crooked teeth, there are many areas that your toothbrush cannot reach during brushing. Over time, bacteria and plaque can accumulate, leading to decay and cavities.

Gum Disease

Plaque buildup can also affect your gums and cause irritation and inflammation, leading to periodontal disease. Gum disease is much less likely with straight teeth and good oral hygiene habits.

TMJ Disorder

An improper bite can lead to pain and stiffness in the jaw joints and other symptoms of TMJ disorder. Orthodontics can correct an improper bite and relieve pressure and discomfort in the area.

Dr. Armstrong and his staff are well-organized and exude both the utmost care and professionalism.

I've never stayed with one dentistry as long as I have with them (5+ years) and every visit there has been nothing short of outstanding. While they provide excellent dental care, I find their customer service to be unmatched! One of the workers there even messaged me on Facebook to check up on me after I had a shoulder surgery. They truly care for your entire well being in addition to your dental needs. I cannot recommend this dentistry enough!

The Orthodontic Treatment Timeline

At River City Dentistry, we've seen firsthand how life-changing orthodontic treatment can be.
At River City Dentistry, we've seen firsthand how life-changing orthodontic treatment can be.


During your initial consultation at one of our dental offices in greater Chattanooga, we will use advanced 3-D imaging to evaluate your teeth and create your custom treatment plan. This advanced tool gives us an incredibly detailed understanding of your teeth and jaw, and whether braces or Invisalign will be best for you. We will provide a complete walk-through of what to expect and answer any questions or concerns you may have.


If you selected braces, treatment begins by bonding brackets to the teeth and looping a wire through them. The braces are gently tightened to encourage the teeth to start shifting into place. For Invisalign patients, digital impressions are taken of your teeth and sent to a lab where dental technicians will create your custom set of aligners. Once the aligners are ready, you'll return to our office for a fitting.


Braces patients will visit our office every month to have their braces adjusted. This may consist of changing the rubber bands on your brackets or receiving a new wire. Patients with Invisalign will also have periodic appointments to ensure treatment is going smoothly. Invisalign aligners must be worn for at least 20-22 hours a day to achieve the desired results.


Your new smile is complete and ready to show off to the world. Braces patients must wear a retainer to sleep every night to ensure their teeth remain in the proper position. Invisalign patients can wear retainers or their last set of aligners to maintain their results. It is also crucial to keep up with routine dental visits and practice good oral hygiene.

Straighten Your Teeth at Any Age It's Never Too Late

Here at River City Dentistry, we have orthodontic patients of all ages. It is a common misconception that only children or teenagers should get their teeth straightened.

If you're an adult who is ready to enhance your appearance and get the straighter smile you've always wanted, it's never too late to get started. Did you have braces but your teeth have shifted over the years? We can treat that too. We're happy to learn about your cosmetic needs and determine which option is best for your lifestyle. Typically, Invisalign is the most popular option with our older patients because of how discreet and convenient they are.

Our team has years of experience helping patients throughout Chattanooga feel more confident, and we encourage you to schedule your consultation with us today.
