Orthodontics
Orthodontics moves teeth into better positions. Beyond appearance, well-aligned teeth are easier to keep clean and spread the forces of chewing more evenly.
What it can correct
Crowding, gaps, teeth that stick out, and bites that do not meet properly — in teenagers and in adults.
Options today
Traditional braces and clear aligners each have their place. Which one suits you depends on how far the teeth need to move and on how you live.
