Dental Care Services

At the Norris Dental Science Center, we provide a wide range of oral health care services to patients, from routine checkups and cleanings to fitting braces and treating oral disease.

Under the supervision of our expert faculty, dental students and residents (dentists in training) provide high-quality care at reduced rates. Since we are a teaching institution and care is delivered in an instructional environment, treatment times are sometimes longer than in a private practice setting. You may need several appointments to complete your treatment.

Some clinics require a referral from your dentist before you can make an appointment; others are by self-referral. See the clinic descriptions below and visit the clinics’ individual web pages to learn more.

Routine Care and Evaluation

All first-time patients (other than those needing emergency care or referred to our specialty clinics) will receive an initial evaluation of oral health in the Center for Diagnostic Services. Patients are then assigned to a student within a particular group practice, overseen by one of our faculty. Patients who need routine care (such as a checkup or cleaning) are seen in the Norris Dental Science Center Clinic or the Dental Hygiene Clinic.
