My experience getting 4 front crowns could not have been made any easier! The office staff are so comfortable to be with and very knowledgeable about all aspects of what to expect. I am very happy with how my mouth looks now. Thank you very much.

Dr. Weierbach and his amazing dental assistants Melissa, Chelsee, and Amanda worked tirelessly to create and perfect an outstanding set of dentures for me. My case was truly unique! Their level of professionalism, dedication to their patients, and their smile is exceptional. They are truly perfectionists. The whole staff treats you like family, so much so my husband is now seeing them!! Trish V. Narvon, Pa

Patient Review

Hello guys, I feel discouraged. I spent a lot to have veneers and straight teeth. At the time when I received veneers I had mentioned a permanent retainer which wasn’t recommended. I wear my retainer every night and my teeth are still shifting back to how they used to be. If I had known I’m not sure I would have spent this money. I’m not sure what is recommend at this point - Paying for braces doesn’t cut it and I don’t feel that the plastic retainers hold my teeth into place.

I have been to MANY dentists, periodontist and surgeons over the years. Thus office, doctor and staff are by far the best ! The attention to detail, the state of the art equipment and the atmosphere of this office are all a 10+! Just had a crown put on (I have several from previous dentist) it looks and feels EXACTLY like my tooth! Shape, color match and feel! I left feeling like I was at the dentist of the rock stars!
