Adult and children’s orthodontics serve the same goal, improving alignment and function, but methods and timing often differ. Adult treatment typically involves more complex issues like bite correction or prior dental work. Children’s orthodontics, on the other hand, can use early intervention to prevent future problems. We tailor care to the needs of both age groups for optimal results.
