We go above and beyond to provide educational care that transforms your smile and helps you develop excellent oral health habits!

Cleanings and Exams

Having a dental practice perform a checkup and regular cleaning gives a preventive approach to dental care. These general dentistry treatments help prevent problems with your teeth, gums and jaw bones, or they catch and manage problems before they worsen. During your visit, our doctors will take a picture of the current standing of your dental health and what would be needed to keep your oral hygiene in its best state.

Teeth Whitening

A common request we receive is how to make a smile whiter and brighter. This is a relatively simple and quick treatment option that can be performed periodically. Certain foods and beverages, such as wine and coffee, stain the teeth and contribute to discoloration.

Porcelain Crowns

Getting porcelain crowns is the best way to have a very natural looking smile. They are used when simply filling in a tooth is not an option. There are times when they decay is so bad that we just have to use a porcelain crown.

Veneers

Porcelain Veneers are wafer-thin, custom-made shells of tooth-colored materials designed to cover the front surface of teeth to improve appearance. These shells are bonded to the front of the teeth changing their color, shape, size, or length.

Donald R. Hermansen, DDS

Dentist

Dr. Hermansen began his higher education by gaining a Bachelor of Arts in biological sciences at California Lutheran College (now University). He then continued towards his doctorate by graduating from the University of California San Francisco (UCSF) in 1973. He has since become a member of the ADA® and received the following certifications and awards:

California Dental Association — Certificate of Appreciation for volunteering on the CDA Council on Peer Review (2010 – 2016)
San Mateo County Dental Society — Board of Directors’ Award
Since 1976, Dr. Hermansen has been providing quality dental care in Redwood City, California. Although he does believe in the value of his work, he also seeks to continually improve his skill set to provide the best service possible for his patients. Dr. Hermansen prioritizes his continuing education as he attends classes (usually monthly) on a variety of subjects. This is well above the mandatory amount, thus enabling Dr. Hermansen to provide advanced care to his patients.

Dr. Hermansen has volunteered in a number of ways over the years. This includes participating in school screenings, health fairs and career day presentations; providing free dental care through local and statewide organized programs; serving as a dental society board member and committee chair; serving as a dental alumni association board member and past president; participating in CDA Cares; and serving for six years on the CDA Council on Peer Review.

His goal as a dentist is to help patients understand their own oral health and allow them to be their own best advocate in maintaining their oral health. This way, he can help their teeth last a lifetime.

Dr. Hermansen has been married since 1975 to Holly, who is a registered dental hygienist. They have two daughters and two sons, and they enjoy the company of their six grandchildren. His hobbies outside of the office include gardening and reading.
