Dr. Willi7692am Mauthe
A Wisconsin native, I received my training from the University of Wisconsin and Marquette Dental School. In 1967, after two years interning in the United States Air Force, I opened up my current practice in Fond du Lac. Along with several post graduate courses in cosmetic dentistry, I have crafted over 5,000 veneers and caps elevating the technique of cosmetic dentistry to an art form.

Dentistry has undergone a plethora of changes over the last few years and will undergo an entire new set of changes in the new millennium. I’ve made a commitment with our staff and myself to continually update our techniques and services with continuing education. We recently attended a week long seminar at the prestigious San Francisco Dental School where we implemented all the latest techniques in completely changing the smile of one of our patients that attended with us.

Welcome Dr. Mike Messer to Mauthe & Associates!
Bio coming soon!




The Fond du Lac Cosmetic Dental Center has shared its results with dentists throughout the states at past doctorate courses. We’ve included full mouth restoration courses at the Peynke Institute in Miami, the Pentegra Dental Group in Phoenix, the Clinical Research Association (CRA) in Provo, UT and just recently at the PAC Five. We believe a smile is as important to a positive self image as health, fitness or education.

Choosing a dentist to change your smile can be a big decision. I’d like to welcome you to call and make an initial consultation where I’ll listen to your concerns and plan a course of action to accomplish those goals.
