Dental Education

Taking care of your teeth should be fun!
We believe that teaching your child proper oral care at a young age is an investment in his or her health that will pay lifelong dividends. When it comes to the health of your child's primary teeth, there is no better time than now to start practicing excellent oral hygiene. Pediatric dental care ensures your child's primary teeth stay healthy and free of decay and other dental diseases. Brushing along with your child or letting them choose their own toothbrush, encourages proper oral care.  Visiting our office every 6 months for a cleaning is recommended for a healthy, happy smile!


With more than 32 years of experience, Dr. Leo Spyrou & Dr. Jeff Guay provide patients of all ages and needs with the highest possible level of orthodontic care. Our philosophy includes a patient-centered approach to orthodontics. We make every effort to accommodate you, taking the time to care for you, your goals, and your smile. ​As a dual-trained pediatric dentist and orthodontist, Dr. Spyrou practices orthodontics with a complete understanding of children’s growth and development.
