Personalized orthodontic treatments for all ages

Many of our patients want to know the ideal time to begin braces or Invisalign treatment. It really depends on the individual. The most popular time to start treatment is between the ages of 12 and 16, when most permanent teeth are present. And we care for patients of all ages who seek the health and aesthetic benefits of an amazing, confident smile.

We suggest parents schedule their child’s initial orthodontic evaluation at the age of seven, unless referred by a dentist at an earlier age. At this time, we can assess for any problems that may need early correction. In reality, it’s never too late to attain straighter teeth and a compliment-worthy smile. We now treat an increasing number of adults seeking the important health and psychological benefits of a transformed smile, and they appreciate today’s advanced, less-obtrusive braces and Invisalign options.

Let us help you determine which treatment option is ideal for you. Take advantage of our no-cost consultation, including a complimentary orthodontist exam, free X-rays, and a personalized braces or Invisalign treatment plan.
