About Us About Peninsula Family Dentistry

Healthier Teeth—Healthier You

What are you looking for in dental care? Clean, whiter teeth? A prettier smile? An end to tooth pain? An expert dentist with a gentle touch?

Your health

At Peninsula Family Dentistry, we want to help you achieve these and more. Yet, our first priority in providing you excellent dental care is helping you have the healthiest mouth, teeth and gums possible. At Peninsula Family Dentistry, we know that your oral health is intertwined with your overall health. Not only does your mouth enable you to receive nutrition for energy and health, but problems in your mouth can impact the rest of your body. On the flip side, the mouth can give off signals about what is happening elsewhere in your body. Therefore, thoroughly examining your mouth and gums and learning about your health are among the first things we do.

Our care

At Peninsula Family Dentistry, we provide individualized care to our patients—from babies to the elderly—because each person and each stage of life brings unique considerations. At every appointment, we will ask about any health concerns so we’re always helping you understand and choose what’s best for your teeth, gums and overall health.

A place you can trust

We would love to earn the privilege of caring for you and your family as our own. Together, we’ll help you achieve your goals and maintain your best oral health. It is our desire that you’ll appreciate our compassionate care, use of the latest technology, friendly style and gentle touch.

I can recommend Dr. Thomas Duffy without reservations. After another dentist ruined one of my teeth, I decided to see Dr. Duffy. I am so glad I did, and wish I had gone to him first. Dr. Duffy is an excellent dentist. He’s very skilled at working with his hands. He also has a very good demeanor and keeps his calm; he has a good sense of humor, and treats patients with respect and kindness. I recommend him without any reservations. Our family are all very pleased with the results.

Clara,
a very satisfied patient
