Giving Back to Our Community

Dr. Yu and Adult & Pediatric Orthodontics proudly supports Healthy Smiles for ME, INC. to reach those children who need us most.

We work closely with school nurses to identify children with dental needs. When a child is identified with emergent needs, Healthy Smiles for ME coordinates treatment with a local dental office.

If a family cannot afford to pay for treatment, Healthy Smiles for ME guarantees the bill gets paid and the child gets to have a happy, healthy smile.

For more information on how you can donate to Healthy Smiles for ME, visit their website.
