Welcome to Costa + Williams!

Take a moment to explore our practice by watching our overview video. Discover why we offer a better dental experience.

A better dental experience

Dr. Costa and Dr. Williams started their James Island dental practice from scratch in 2011 with the vision of creating a better dental experience for people – one where quality, integrity, and personalized care reign supreme. And one where the experience could be stress-free, anxiety-free, and pain-free.

While dental visits can be associated with negative experiences, we created an office environment that is enjoyable, makes you feel at home, and calms your anxiety. We are proud of the high quality and attention to detail we bring to our craft and enjoy being a positive part of your day. Unfortunately, because much of the healthcare world has moved towards higher volume, their patients have gotten used to having limited time for getting any questions answered and having treatments explained.

When you visit Costa + Williams, you don’t have to wait. Our practice is geared to provide a better dental experience, and that’s why we schedule fewer patients, giving us the time to consistently do our best work. The entire experience is made easy, comfortable, and enjoyable. We keep you informed, take the time to get to know you, answer all your questions, explain the details of your treatment, and ensure that the costs of care are transparent.

Services tailored to your comfort

Our team is committed to providing excellent service and treatment at every visit. From our friendly receptionists to our caring hygienists, you will always feel comfortable when coming to Costa + Williams Dental Health Care.

Still have a fear of the dentist? You are not alone, and we can help. We have multiple options, including the use of nitrous oxide (laughing gas) and oral medications that allow you to get the care you need without fear and anxiety holding you back. Your experience can be a restful, pain-free visit.

We understand that each patient is unique, so we strive to customize your experience by listening to your concerns and answering any questions you may have. No patient is ever rushed, upsold or pressured.

  • Check-ups
