Dr. David Wilhelm

With over 35 years of experience, Dr. Wilhelm has designed his state-of-the-art office with one thing in mind: to ensure that patient comfort is our number one priority. You’ll notice the difference from the moment you arrive because the office reception area has the hallmarks of a five-star hotel, and your treatment will have that same caliber of care from start to finish. Nothing has been spared to make the patient feel at-ease and welcomed.

Sensitive to the fact that many patients feel apprehensive about visiting the dentist, Dr. Wilhelm and his team go out of their way to ensure that each patient feels comfortable and at ease from the moment they arrive. Freshly baked cookies and custom-brewed coffee are just a few of the many comforts of home in our warm and comfortable environment. Dr. Wilhelm has special dental chairs that massage the upper back during treatment, and each room has satellite TV entertainment and DVD players for a pleasant diversion. Still nervous? Nitrous oxide is available for those who prefer it.

Dr. Wilhelm utilizes the best technology has to offer for better patient care. The water that we use is sterilized water, not city tap water. Dr. Wilhelm explains that research has shown that normal city water, which is not sterilized, can introduce bacteria into the oral environment that can delay healing or cause secondary infections. Dr. Wilhelm’s office also has its own in-house dental laboratory for your convenience.

In a field where technological advancements continue to expand at a rapid pace, Dr. Wilhelm’s office remains on the leading edge of dentistry. His patients enjoy advanced laser dentistry for everything from routine fillings and ZOOM! one-hour tooth whitening to gum re-contouring and hygienic treatments. Dr. Wilhelm also offers aesthetic imaging which allows patients seeking a smile makeover to see before and after pictures of their new smile prior to the work being done. Implant dentistry and Invisalign® clear braces round out Dr. Wilhelm’s extensive menu of dental services.
