The hygienist staff was great (added a star for them), but his work is not very good. Every time I went, he would come up with a reason why I needed a filling. When I'd get these fillings, they would always hurt and have to be redone, and still hurt for an extremely long time afterwards. I finally got suspicious an got a 2nd opinion on a tooth that, believe it or not, he wanted to put a filling in.

Apparently he just likes to use his drill. If he says you need a filling, I caution you to get a second opinion. In the tooth he wanted to fill, apparently it wasn't even in consideration for needing work. To top it all off, he's really socially awkward too

I highly recommend John Krupka and his team. He was thourough, straight forward, polite, and most importantly, honest. I never once felt like a dollar sign. I felt like a respected person with choices to make, and I also felt that I was given all the information to make the choices that best fit me. I have had bad experiences with dentists in the past, and I just wish I had made this switch years ago.

I'm writing this review for my mom, she was very impressed by the service and speed at Krupka Dental. She had to have two teeth pulled for the first time and said it was virtually painless after the initial numbing shots. Total time in the chair was less than 15 minutes. They made everything quick and easy. She says she will continue to go here and recommend them versus the well known chain dental office she used to go to.

This dentistry is simply amazing and the dental hygienists there are some of the nicest people you will meet along with their very efficient dental work. All in all I would recommend anyone that needs dental work done to go to this place and go for a check up.

Growing up I never really had a "pretty" smile. I had stains from when I was little due to medication. I went from dentist to dentist and everyone I talked to said that my staining was so deep that I had get the teeth removed and get implants. I was devastated. Fast forward few years countless dentist I decided to get braces and I found him. From the first appointment I felt understood and not embarrassed.

I got my braces on and I wasn't terrified to to back for my routine check ups. I was actually excited. I got engaged and planned my wedding. They made sure my braces where off before my wedding. They also came up with an idea to help get ride of the staing. It was a little pricey but I figured I would give it a try. The day the took off my braces they used this special paste on my teeth and scrubbed them with some tool.

After they showed me my new teeth. I'm not exaggerating I went home and cried. My teeth are beautiful. I never felt like this would happen. I feel so comfortable and confident with my smile that for 20 years I never was. Growing up I never smiled but since the day they took them off I smile thanks to them. It means the world to me. If your thinking about it or worried about the price. I'm telling you it is 100% worth it. It truly is.

Dr. Krupka has been my dentist of choice since his arrival in Kaukauna. He and his staff are always friendly and considerate. All equipment is "state of the art"; I'm impressed with the capabilities available to patients. Thanks to their efforts and guidance, I am in good shape. Today I had a routine checkup/cleaning; all is well. As usual I received good advice and guidance. I like coming here!

I have been a patient of Dr. Krupka for the past three years and in my experience he is very professional, efficient, and patient oriented. He has explained to me every procedure and has taken the time to answer all my questions. He is thorough, careful, and makes me feel that I am in good hands. It helps to know that his office is equipped with the latest technology. The staff is very friendly and professional. I am also glad that the appointment times are respected.

Dr. Krupka is experienced and I like how he's aggressive with his use of technology and everything. He always goes to school and learns more to keep helping his patients. The new dental hygienists are great too. I appreciate their appointment reminders.

The staff at Dr. Krupka's are just wonderful. They've helped me through a lot. I've had a lot of dental work done and I'm very pleased with the doctor and his staff. They couldn't make me feel more welcome and comfortable.

Dr. Krupka is good about sending postcards to you in the mail if you haven't scheduled an appointment yet or when your next one is upcoming. My family members have also gone to him for orthodontic work in the past and he's done a good job.
