What is prosthodontist?

A prosthodontist is a dentist with special training in the diagnosis and treatment of patients with extensive restorative dental needs. To become a prosthodontist, a dentist has to complete an additional two or more years of advance training. Prosthodontists can perform routine, as well as complex restorative procedures. Serving as the “architects” of a dental treatment plan, prosthodontists collaborate with general dentists, specialists, and other health professionals to develop solutions for your dental concerns.

  • Complex case management (i.e. cleft palate, post cancer patients, Parkinson’s patients, etc.)
  • Dentures, partials, bridges, etc.
  • Traumatic injuries
  • Restorations over implants
  • Temporomandibular disorders (TMJ) – Jaw joint problems
  • Aesthetic dentistry (cosmetic)

Dr. D. Jay Lambert

As a general dentist, I enjoy seeing patients of all ages, especially children. The staff and I are working hard to make sure that children feel comfortable at Coweta Dentistry. During the time I spent working in the pediatric department at UAB, I learned the latest techniques to ensure that children have a positive experience in the dental office. I plan on using the latest technology and my experiences there to make both children and adults feel welcome and at ease at Coweta Dentistry.

Newnan has always been an important part of my life. I was born at Newnan Hospital and my family is deeply rooted here. My parents operate Lambert Pharmacy, just off the Highway 29 in Palmetto. I went to Sandy Creek High School in Tyrone before attending Auburn University. There I majored in Chemistry and decided that I would pursue dentistry as a career.

After graduating from Auburn, I was accepted at the University of Alabama at Birmingham School of Dentistry. At UAB, I received an excellent education in all areas of dentistry and I graduated with a DMD degree. Pediatric and restorative dentistry were two areas I truly enjoyed in school and I plan to concentrate heavily on those areas in my practice.

I am greatly honored to be a part of this practice. I look forward to coming back home and meeting you and your family. If I can be of service to you in any way, please feel free to contact me.

What People Are Saying

I came in on 3/25/2019 to have a deep cleaning done. This wasn't an easy task as I still have braces on and have no date in the near future for their removal. Nonetheless, from the moment I walked in, the staff member at the front desk was very welcoming. The doctor who came to numb me was very kind and comforting. The young lady who did my x-rays was also, and the hygentist was simply amazing. He was very friendly and caring. He took time to explain everything he was doing and checked in often to ask how I was doing. He was also very personable. So, I'd like to thank you all for such a pleasant and wonderful dental experience!!!

The dentists & all the staff are very caring, knowledgeable & efficient. I’ve had a lot of dental work done over the years & this practice is top notch!! I’ve not had any pain with any of their procedures, in fact, I actually fell asleep during a root canal (no calming medications involved) & woke myself up snoring!! True story! I am grateful for their excellent care & highly recommend them!!
