Our motto here is prevention before treatment. We believe having your routine cleanings are the key to achieving optimal oral health, and saving you money in the long run. Your routine appointments will include your cleaning, X-rays, an exam with Dr. Tim, and any necessary gum scoring and fluoride treatments. We will also help you detect any issues and if imperative, develop a treatment plan best for your case.


We are here to help you understand the importance of oral health, why treatment is necessary, and your insurance! We also understand that finding time to come in for treatment can be difficult so we offer treatment times all day Monday through Thursday. 

Discover a new dental experience at Chatham Dental Center! We look forward to caring for you and your family's dental needs.
