Traditional Metal Braces
Traditional braces remain a proven option for correcting a wide range of orthodontic problems. They can be used for children, teenagers, and adults and are designed to gradually move teeth into better alignment.
Clear & Ceramic Braces
Ceramic braces provide an alternative for patients who prefer a less noticeable orthodontic appearance. Tooth-colored or clear components can help make braces more discreet.
Invisalign Clear Aligners
Invisalign uses a series of clear, removable aligners designed to gradually move teeth. Because the aligners can be removed when eating and brushing, they can be a convenient option for many patients.
Retainers
Retainers are commonly used after orthodontic treatment to help maintain the position of your teeth. Following your orthodontist's retainer instructions is an important part of protecting your treatment results.
