Services
Invisalign
Invisalign uses custom-made, removable aligners to straighten teeth discreetly. Ideal for teens and adults, this treatment offers comfort and flexibility, allowing patients to maintain oral hygiene and eat freely. Most cases require 1218 months of consistent wear.
Metal Braces
Durable metal braces correct misalignment efficiently. Modern designs are smaller and customizable with colored bands, making them popular for children and teens. Treatment duration varies from 1836 months based on complexity.
Clear Braces
Clear braces provide an aesthetic alternative using tooth-colored brackets. Effective for teens and adults, they blend with natural teeth while delivering results comparable to metal braces. Treatment spans 1830 months.
Non-Surgical Orthodontics
This approach addresses underbites, overbites, and open bites without surgery. Techniques include strategic tooth movement and appliances, suitable for mild to moderate cases. Treatment lasts 2032 months.
Early Treatments
Early intervention (ages 79) guides jaw growth and prevents severe issues. Methods include appliances to correct habits or align jaws, reducing future surgical needs. Timely care ensures optimal dental development.
