Got infection after root canal procedure..had to go to ER. Tooth needed to be pulled. You're gambling with your life going to this dentist!!!! Dr. Dennis Oppenheimer is incompetent dentist!

Terrific staff and service!

Pulled the wrong tooth out. I now need to get an implant at great expense. STAY AWAY!
The staff was very accommodating but that's the end of my positive feedback. I went in for a filling and ended up with an unnecessary removal of one of my teeth, a painful root canal because Oppenheimer hit a nerve, an off-color dental cap that cuts into my gums, and he ignored the tooth which still needs a filling. Consider getting a second opinion before any major procedure. His main concern seems to be cosmetic dentistry over dental health.

I have permanent damage from “Fast Braces” that Dr. Oppenheimer did. I was in extreme pain for a long time and he didn’t do anything about it. Have trouble sleeping and eating… Went to see a few other orthodontists for opinion and they told me this was the worst they’ve seen. They’ve concluded this was done extremely carelessly and without experience…I have about $20 thousand in cosmetic work plus $7 thousand to correct teeth alignment....my teeth are now permanently damaged…

The WORST EXPERIENCE EVER!!!! Better get a second opinion if you still want to have any teeth left! Committed medical malpractice.... will require thousands of dollars to repair...Found out he was FIRED from his previous job nearby for wanting to do Botox and Braces with no experience...His breadth stinks from a mile away, always makes for unpleasant experience. If he doesn't take care of his teeth what makes you think he will take care of yours??? Unethical, incompetent sick individual...wou

Dr Oppenheimer is one of the most compassionate & gentle Dentists I've ever been to. I have a fear of dentists & he recognizes this and does his best to keep me calm & pain free. He has been my dentist for approximately 12 years & I wouldn't think of changing. Highly recommend!
