Orthodontic Services


Straighten your teeth and correct minor bite problems with these removable clear plastic aligners that make orthodontic treatment faster, more comfortable, more hygienic, and invisible.


There’s no substitute for traditional braces when it comes to treating severe malocclusions like overcrowding, large gaps, and a severely misaligned jaw. Metal wires and brackets are the only orthodontic treatment capable of complex tooth movements. 

We also carry ceramic braces for a more discreet orthodontic treatment as these braces are tooth-colored and can be paired with transparent archwire and white elastics.

Phase 1 Orthodontics

Phase 1 or early interceptive orthodontics address abnormalities in your child’s tooth alignment and jaw growth at an early age while they are still developing. Intervening early prevents the need for future orthodontics and can encourage proper growth, facial development, and tooth alignment while your child still has some deciduous teeth.

Space Maintainers

These stainless steel or acrylic oral appliances prevent shifting teeth and improper eruption of the permanent teeth caused by premature tooth loss in deciduous teeth. A band or crown is placed around an abutment tooth and a wire holds the space from the previous tooth open.

Teeth Whitening

Orthodontics is about correcting a crooked or misaligned smile but we can also whiten your smile so you’ll have the full package. If you have a special event coming up, we offer in-office teeth whitening for fast and effective results that can lighten your teeth by up to 10 shades. 

For maintenance or everyday convenience, we also offer at-home whitening kits that are created from impressions of your teeth. You’ll wear these trays at home for 2 weeks.
