I have spent hours in the dental chair for some appointments related to the procedures I am having done. The staff care about your comfort and Dr Weirbach personally calls to follow up. They do not settle for mediocre.

Absolutely amazing care and treatment from start to finish. Every visit is a pleasure. I went from having pain and discomfort every day from TMJ to no pain at all. That would not be possible without Dr. Weierbach and his staff.

Patient Review

I was recommended to you by a friend and pulmonary NP for sleep apnea appliance. During the examination the uneven lower front teeth were talked about. Dr Weierbach explained cosmetic countouring to me. I decided to have it done! I was amazed that a simple procedure could make such a visable difference to my smile. So sad that for a long time when out in public a mask had to be worn and smiles not seen!! I am very happy for sleep apnea appliance and even front lower teeth! Thank you
