“I would like to say thank you with my greatest appreciation. I came into my consultation with a sense of anxiety I could not shake. You listened to me and my feelings then carried through, which eased my worries.”

Anna C.

"To say 'Thank you' doesn’t seem like nearly enough to show my appreciation for everything you and your staff have done for me during my recent surgery. 
I love my new smile and it has impacted my life in such a positive way."

Cindy W.

“I wish to express my appreciation to you for getting me in with my emergency.  You were very courteous and made me feel comfortable. I’ve had no further issues and would definitely recommend you due to your professionalism.”

Our Patients


Oral and maxillofacial surgery is a dental specialty that bridges dentistry and medicine. Tri-County Oral-Facial Surgeons, P.C., delivers a broad scope of care including the management of wisdom teeth, extractions, dental implants, trauma management, corrective jaw surgery, and care of tumors in the oral cavity and salivary glands. Dr. Engroff and his staff will evaluate your particular condition and advise you of your treatment options.



A healthy, beautiful smile makes you feel more confident. Dental implants may be life changing because they can restore a smile to its original beauty.



Teeth may need to be extracted for many reasons. The most common reasons are preparation for orthodontics, insufficient space in the mouth, and decay and infection in the tooth or surrounding bone.
