Zwahlen & Marshall Family Dentistry

Fantastic experience: Yesterday I went to this dentist office for an emergency extraction for my daughter. When I tell you that Dr. Zwahlen is God sent and his staff are angels from above, I’m not joking. I called during Thanksgiving week on a Monday, when it is swamped with people and they fit me in to see my autistic, special-needs daughter with a broken cap and we were able to not only removed her tooth, but also keep her at ease throughout the whole time without having to sedate her. I am just utterly grateful to this Office for taking their time to help us when they really did not have the time or space to. So many many thanks we appreciate you so much Dr. Zwahlen and staff

He and the assisting nurse were incredibly patient and highly accommodating to my needs, pausing when I needed to rest my mouth, working gently on teeth, and providing additional numbing injections to alleviate my pain as much as possible. They also were open to hear my needs and answer questions I was able to ask during the filling procedure. When I was numb in my mouth, they were still able to comprehend what I was trying to say or ask, and they accommodated me as much as possible. The dental hygienist Darlene was also kind enough to answer many questions I had when I had my teeth cleaned prior to my fillings being placed.

Also, I had 3 fillings done just a few months ago and I felt sharp edges so I brought it to Brian’s attention. He said they were crumbling. Why? I just had them filled! Also, one of those teeth has now broken off and looks like I will need more work to a tooth I just paid to have filled! I will give a big shout out to Dr Lynn however.
