Bad work, bad customer service, and bad enviroment. I 1st went there 1 year and six months ago for my semi annual cleaning. I had no pain or no problems. They said I need to take the silver fillings I had in my mouth out and that I needed a root canal. The day of the root canal. I explained to the Dr that I researched a root canal online and I don't think that was the issue. He looked a little closer and found that I had a crack in one of my teeth. The root canal was not needed, but I still needed a crown b/c of the crack. When his work was complete, my mouth never hurt so much. I've experience high sensitivity where they replaced the fillings. The crown was too big and hard to floss and there was still pain under the crown. I went back several times, they were unable to provide relief. I finally got smart and changed doctors.
