Keeping your teeth healthy and happy is our main concern. That's why we provide:

  • • Gentle checkups and cleaning

Restorative Dentistry


Tooth-colored fillings
  • To fill and protect your teeth from cavities
Crown & Bridge
  • With new materials and techniques, the procedure is much simpler and the results more natural-looking than ever before. They are made of tooth-colored porcelain and can replace damaged, cracked, or missing teeth.
  • A fancy term for root canals. Dr. Dan has performed hundreds of these procedures and is extra gentle so you don't have to worry.
  • Our dentures are custom-made to look like your natural teeth and fit comfortably. They can restore function and give you a new-found confidence in smiling, talking, and eating.
  • Implants are one of the most important dental innovations of the last 20 years. They can replace one tooth, or a whole mouthful, and they rival natural teeth in appearance and function.

If you have dental insurance...

All services rendered are charged directly to the patient, and the patient is cltimately responsible for the account regardless of insurance coverage. Our insurance coordinator deals with many different insurance companies. Insurance companies can change dental benefits and deductibles at any time throughout the year. We do our best to provide you with accurate coverage estimates based on information available to us. Dealing with insurance companies can be difficult and time consuming. As a courtesy to our patients, we will submit all dental claims and provide any necessary information to your insurance carrier. Please make sure all your insurance and personal information is current with our staff so that we may file with the correct information. We will make every effort to expedite the processing of your dental claims. Government regulation requires insurance companies to pay claims in a timely manner. Any insurance claim denied or remaining unpaid after 60 days will be considered the responsibility of the patient.
