Patient Review

I consulted three other dentists within the past year, before finding Dr.Weierbach. My experiences under his treatment and the care of his staff are the best I've ever had. I look forward to continuing care in the future.

Patient Review

I have had dental implants for thirty years due to a car accident. I was having severe pain and irritation from my dental implant appliance. Dr Weirerbach knew exactly what was needed, it didn't fit properly and the hardware was outdated. The temporary appliance fit better than the actual appliance I had from a prior dentist. I have my permanent appliance now and it is absolutely beautiful and better yet it fits perfectly. My teeth look real and very much like my actual teeth looked. I am very anxious at the dentist and Dr Weirerbach and all of his staff were very accommodating and kind. I could not be more thrilled and grateful for my new smile and the fabulous customer service provided. I highly recommend Dr Weirerbach and staff!

Patient Review

I went to Dr Weierbach because I was unhappy about how my current orthodontist was treating my bruxism (teeth clenching at night). He assessed me and suggested trying Botox to relax the muscles. Within MINUTES, I felt relief and my face looked thinner as the muscles relaxed (turns out I was totally ripped, but only on my face, hahaha!). I slept with no guard and no medicine for bruxism for the first time that night in over 20 years. Night two has also passed. I am sleeping better and I have no pain in my jaw in the morning. Literally life-changing!
