Dr Robert LaCosse is the first and still the only general dentist north of Minneapolis to have been awarded full accreditation from the American Academy of Cosmetic Dentistry. With over 6000 members, the AACD is the largest organization in the world dedicated to the art and science of cosmetic dentistry and only 300 members have reached the level of accreditation. Dr LaCosse runs a general dental practice with a strong emphasis on the particular skills required for achieving excellent results in cosmetic dentistry and complex restorative or reconstructive dental cases. Comfort, respect, trust and value are stressed in all of his procedures. Dr LaCosse has also been awarded the prestigious Fellowship in the Academy of General Dentistry and the invitation only Fellowship in the International Academy of Dental Facial Esthetics. He is the only dentist in the Midwest to hold all of these honors at the same time. In addition, he was the first dentist in Duluth to complete the Post Graduate Continuum in Esthetic Dentistry at the University of Minnesota. He is a published author on the topic of Cosmetic Dentistry, a respected lecturer in Cosmetic Dentistry topics at several organizations including the University of Minnesota, and is a contributor for dental topics at KBJR news. As owner of the Lake Dental Group in Duluth, his primary goal is to work together with each patient in a comprehensive and caring way to achieve the best possible dental care. New patients are always welcome.

I highly recommend Dr Lacosse, thorough, informative and friendly !!

I have been so totally pleased with Dr. Lacosse and his staff. From the help at the front desk, to my cleaning appointment and now with restorative procedures....Dr. Lacosse's office has made this a very comfortable experience. We were able to complete all of the needed restorations with minimal discomfort on my part, and considering the difficulty I have with dental procedures, this was a HUGE bonus. I will most definitely recommend Dr. Lacosse and his staff to my friends and family.

Dr Lacosse... you have an amazing dentistry and great staff. I've had good dentists over the years, but this was the most impressive experience Ive had. I got a new crown and had an old filling replaced. Painless and perfection. Thank you

Impressive facility with parking right outside the front door, state of the art equipment, thorough exam, and friendly and patient staff as we figured out insurance and out of pocket costs. Very impressed! Will be returning for a crown on a broken tooth that is only going to take one day (1.5 hr.) to complete!
