Orthodontic treatment can help you achieve a beautiful, healthy smile at any age. Our services include phase I orthodontics, which focuses on gentle jaw correction in children, and phase II, which emphasizes alignment in adolescents and adults. It usually involves braces and begins when most of the adult teeth have emerged.

Dental Implants

Checkups and Cleanings

Compass Dental Group helps you maintain good dental health by providing routine evaluations, preventive cleanings, and basic oral care. These services, which we carry out with your comfort in mind, can detect common dental problems during their early stages, protecting you and your family from time-consuming and potentially expensive treatments.



A dental crown is a restoration that completely covers your natural tooth. While your dentist may recommend a crown if you have a decayed or damaged tooth that can’t be repaired with a filling, it can also act as an anchor for a dental bridge or complete a dental implant restoration.


Teeth Whitening

Teeth whitening is a popular cosmetic treatment that makes your teeth brighter and more attractive. With our professional teeth-whitening services, you can either whiten your teeth in the comfort of your home or in our office. We make teeth whitening comfortable and safe for our patients while achieving the natural-looking results they desire.



Periodontal disease, also known as gum disease, is a common oral condition that can result in tooth loss and serious systemic health problems when left untreated. Periodontal therapy at Compass Dental Group can help you maintain your oral health and beautiful smile.


Clear Aligner Therapy

Unlike conventional metal braces, clear aligner therapy is bracket- and wire-free, making it more comfortable and less visible. This orthodontic treatment straightens teeth using clear dental appliances specially created for each patient. By applying gentle pressure over time, these aligners gradually move the teeth into their ideal positions.

Here's what our patients have to say.
