Services
Metal Braces
Modern metal braces offer efficient tooth alignment through durable brackets and wires. Our specialists use this proven method to correct complex dental issues with precision. Regular adjustments at our Worcester, Auburn, or Spencer offices ensure optimal results while maintaining cost-effectiveness compared to newer alternatives.
Clear Braces
Clear braces provide discreet orthodontic treatment using tooth-colored ceramic brackets. This aesthetic alternative to metal braces maintains effectiveness while blending naturally with teeth. Ideal for patients seeking less visible correction of moderate dental misalignments in our Central Massachusetts locations.
Invisalign
Invisalign uses custom-made, removable plastic trays to gradually straighten teeth without brackets. Our specialists determine eligibility through comprehensive consultations, ensuring proper wear schedules (20-22 hours daily) for successful outcomes in Worcester County patients seeking nearly invisible orthodontic solutions.
Adult Orthodontics
We specialize in smile transformations for adults seeking improved dental alignment and bite function. Our experienced team addresses unique adult orthodontic needs, including cases requiring combined surgical and orthodontic treatment, with options tailored to professional lifestyles and aesthetic preferences.
Early Intervention
Following American Association of Orthodontists guidelines, we provide early screening at age 7 to identify developing issues. Our interceptive treatments address jaw growth and emerging alignment problems, creating optimal conditions for future dental development in young patients across Central Massachusetts.
