At Greater Portland Health, we understand the importance of oral health for patients' overall well-being at any age. We offer comprehensive dental services for adults at Bayside and for children at Portland High School. In addition, preventive services are offered by dental hygienists on-site at 180 Park Avenue, Riverton Community Center, Portland Public Schools, and South Portland High School.
Through our dental program we are able to offer patients a continuum of care across all of our locations as an integrated medical and dental home. Establishing Greater Portland Health as your dental home allows us to easily coordinate your medical and dental care between your team of healthcare providers. Our re-care system continues to provide dental patients with regular preventative treatment, exams, follow-up treatment, oral health education, appointment confirmations and reminders, referrals, and community outreach to ensure continuous care and long-term oral health. If you require a more complex procedure, a referral will be made to a local specialist. The dental team will assist you with referrals.
