Services
Braces
Traditional metal braces offer reliable teeth straightening for all ages. Our customized treatment plans ensure optimal alignment and bite correction through periodic adjustments. Patients receive comprehensive care with regular monitoring to achieve lasting results.
Invisalign
Invisalign clear aligners provide discreet orthodontic treatment for teens and adults. These removable trays gradually shift teeth into proper position while allowing normal oral hygiene and eating habits. Our Platinum-certified providers ensure precise treatment planning.
Phase 1 Treatment
Phase I treatment addresses orthodontic issues in children aged 7-10. Early intervention corrects jaw development and tooth positioning problems, potentially reducing future treatment complexity through specialized appliances and monitoring.
Retainers
We offer customized retainers to maintain treatment results. Options include removable clear plastic retainers and permanent bonded lingual retainers. Proper retention ensures long-term stability of corrected tooth positions after orthodontic treatment completion.
Surgical Orthodontics
Surgical orthodontics combines braces with jaw surgery for severe bite issues. This comprehensive approach corrects functional problems and improves facial aesthetics through coordinated treatment with oral surgeons for complex orthodontic cases.
