Our story, since 1977

The name is the address. 1330 Congress Street has been home to this practice since 1977, and one of its dentists is the grandson of the oral surgeon who first owned the building.

Some patients have been coming here for over thirty years. It is still the same address.

How we practise

Conservative dentistry, and smiles that last.

The practice describes itself as devoted to restoring and enhancing the natural beauty of your smile using conservative, state-of-the-art procedures. In practice, that comes down to six things.

Planned in full

Comprehensive treatment planning, with restorative and cosmetic dentistry used to help you reach your optimal dental health.

Health care, not disease care

Thorough exams of your teeth and gums, oral cancer exams, and X-rays when they are necessary. Then cleanings, sealants and fluoride to prevent disease.

Your whole health

A review of your medical history keeps the team aware of new medications and any illness that may affect your dental health.

Uncompromising safety

Sterilisation and cross-contamination processes kept to the standards of the ADA, OSHA and the Centers for Disease Control.

Always learning

Lectures, meetings and dental conventions, and membership of professional dental associations, to keep up with new techniques and equipment.

A visit that feels easy

Some patients feel uneasy about the dentist. The whole team works to make every visit as relaxing, comfortable and pleasant as it can be.

I was recommended 1330 from a friend of mine. He gave me good advice. Along with a cleaning, 1330 gave me a gold crown in one of my molars. Terry took her time to help get the fit of the crown just right. She and Dr. Sherwood worked well together to ensure my comfort. Great work overall. Thank you 1330 Dental Associates.
