Services
Biological Dentistry
Our biological dentistry approach considers oral health as integral to overall wellness. We use biocompatible materials and mercury-safe removal techniques to protect patients' systemic health. This service includes comprehensive evaluations of dental materials and their potential impact on the body, ensuring treatments support natural healing processes while maintaining optimal oral function.
Cosmetic Dentistry
We offer veneers, teeth whitening, and Invisalign to improve smiles aesthetically. Our artistic approach combines technical precision with natural-looking results. Treatments are customized to each patient's facial structure and oral health needs, ensuring both beauty and functionality while using mercury-free materials for long-term durability and safety.
Laser Treatments
Our CO2 laser technology treats tongue and lip ties with minimal discomfort. This service includes frenectomy procedures for infants and adults, improving breastfeeding outcomes and speech development. The precision of laser therapy reduces bleeding and promotes faster healing compared to traditional surgical methods, ensuring better patient comfort and recovery.
Airway Evaluation
We assess oral structures affecting breathing patterns using cone beam CT imaging. This service identifies airway restrictions that may contribute to sleep apnea or developmental issues. Early intervention through orthodontic expansion or myofunctional therapy helps optimize breathing capacity and supports proper facial development in growing patients.
Dental Ozone Therapy
Ozone therapy disinfects cavities and gum infections naturally. This service uses activated oxygen to eliminate pathogens without harsh chemicals. Applied during restorative procedures, ozone strengthens tooth structure and promotes gum healing, offering a minimally invasive alternative to traditional antimicrobial treatments while supporting the body's immune response.
