About Orthodontics


Orthodontics is a specialized branch of dentistry that focuses on the prevention and correction of malpositioned teeth and jaws. Orthodontists promote oral health by targeting issues like malocclusion, improper jaw alignment, crooked teeth, spacing, missing teeth and crowded teeth. By treating some of the underlying orthodontic problems that lead to tooth decay and tooth loss, orthodontists help their patients maintain healthy teeth and gums as well as boost their confidence with a beautiful smile.


Orthodontic appliances like clear plastic aligners (commonly known as Invisalign), metal brackets, or lingual braces, work by slowly and constantly moving teeth into a proper position until they are aligned. Conventional braces can be made of metal, ceramic, or plastic, and some are practically invisible. In some cases, seeing an orthodontist for preventative diagnosis and care can help avoid more costly dental procedures later.

Our Approach to Treating Kids

Choosing the Best time to start treatment

The American Association of Orthodontists encourages parents to take their child to see an orthodontist by the age of 7 for an initial examination. Rest assured, Dr. Rooz does not believe in over-treating children. We’ll monitor your child and determine the right time to intervene.

Phased Treatment

Two phase treatment allows orthodontists to correct dental problems while a kid transitions between baby teeth and adult teeth. Managing space for adult teeth to replace baby teeth is critical. 

Successful early treatment in kids addresses structural problems that would otherwise require teeth extractions or surgery, which can become more complicated with age. Early treatment also helps protect flared upper front teeth from injuries mostly leading in tooth fracture.

growth modifcation

Orthodontists can redirect skeletal growth in children using early treatment. An expander on upper teeth is an example of orthodontic treatment that fixes a small upper jaw. Reverse pull headgear (facemask) is another example. 

Most skeletal issues can result in misalignment in teeth or sometimes in the bite. Habits like thumb sucking can adversely impact growth of upper and lower jaws or disrupt developing straight teeth.

What should you expect at your first appointment?

After you check in, one of our orthodontic assistants will perform an oral examination by taking a digital scan of your mouth to evaluate the position of your teeth and bite with our 3D scanning software. Then, Dr. Rooz will review your scans and dental history and medical conditions, and devise a treatment plan.

Dr. Rooz will review your treatment options with you or your guardian, and together you’ll create a personalized treatment plan that fits your lifestyle. Once you’ve chosen a course of treatment, our coordinator will review financing options that maximizes any dental benefits and will help create a payment plan that works for you.

After you finish with your orthodontic care and your teeth are straight, you will receive a clear, removable, plastic appliance called a retainer. You will wear these retainers full time in the beginning, and later you may only wear them at night. This ensures your teeth stay in their ideal position, maintaining the perfect smile you worked so hard to achieve.

Everyone should wear a mouthguard while playing contact and non-contact sports to protect their teeth and gums from injury. Mouthguards can provide protection and help avoid costly dental treatment associated with injuries.
