A very nice and friendly practice. My son has been being treated there for about 3/4 years (5 years when the treatment started and very anxious) now really enjoys going to the orthodontist and is as proud as Oskar after every visit. I can heartily recommend it!

The treatment at Dr. Mertens went without any complications and was able to finish with a great result. He is always friendly and takes a lot of time to explain everything calmly and to adapt the treatment to me individually. I have already recommended him to a friend and also... she is more than satisfied with the result :) The practice team is professional, polite and always gave me the feeling as a patient that I was in good hands there.

I felt very well advised and in good hands at the practice. I had previously started treatment at DR SMILE, but I didn't have the feeling that I was getting professional advice there. In contrast, Dr. Mertens detailed the treatment with me during the first appointments... discussed and all the details explained to me. I am really looking forward to having the treatment done by him!read more

In June I had my Invisalign treatment with Dr. Cherry completed and I'm very happy with the end result! The special thing about the treatment: I was able to carry out the treatment successfully despite a six-month semester abroad in France. The treatment went flawlessly... I could always contact Dr. Report cherry (actually happened once). I would go back to Dr. Cherry come!read more

On the recommendation of my sister, who is a dentist herself, I went to the practice of Dr. Kirsch and Dr. Mertens introduced. I am enthusiastic about the competence and think it's great that I was presented with the result virtually in advance. I can't wait to see the result... to see my own teeth. I immediately felt comfortable in the practice. The whole team is very nice. I can recommend the practice.read more

I had fixed braces as a child and the result after two years was very miserable. I was still happy when the clip was out. Years later I realized that my crooked teeth are not only unsightly but also bad for my health. So i have... started looking for a suitable orthodontist in Bergheim.

Was treated by Dr.Kirsch as a child, was always very friendly and knows what he is doing. I'll be there with my children, 2 have finished the treatment and have super nice teeth. One is still being treated, everything is going great. You get appointments very quickly, whether something is pressing or... is defective (everything is always without problems), e.g.... my daughter lost a splint, could come right over and the new splint was ready in less than 24 hours, practice is well-kept, everything is top. Doctors and team super friendly!!! I can recommend the practice!read more

Teeth have become relatively straight, but the result can definitely be improved! My upper canine tooth is still totally crooked and has now completely shifted again 8 years after the end of the treatment, so that the tooth is shifting my entire row of teeth. The team has always been relative... rude. If I could turn back time, I would have gone to a different orthodontist.read more

Frequently asked questions (FAQs)

Treatment process at your Bergheim Orthodontics Dr. Cherry:

Consulting In a free and non-binding consultation appointment in our orthodontic practice in Bergheim we examine your teeth, gums and misaligned teeth and advise you on the options for aligner treatment. At this appointment we can give you a rough estimate of the treatment costs. initial diagnosis The initial diagnosis is crucial for planning a therapy. Various findings are made on this. The jaw joints are also examined. The following documents are created:
  • Intra- and extraoral photos
  • Digital x-ray of the teeth
  • Intraoral 3D scan
Evaluation and therapy planning: After evaluating the findings, the therapy is planned and the ClinCheck is created. The ClinCheck corresponds to a 3D simulation of tooth movements. Start of treatment: After all aligners have been produced, the treatment can begin. If necessary, small, tooth-colored plastic dots are glued to certain teeth so that even difficult movements can be carried out precisely. You wear each aligner 22 hours a day for 7 days and then switch to the next aligner. Checks are carried out in our practice at regular intervals. Experience visible success in a short time. Retention and stabilization: After the end of the active movement, we recommend inserting retainers in the upper and lower incisor area to secure the results.

In addition to the inconspicuous nature of the treatment method, a major advantage lies in the shorter duration of the orthodontic treatment in Bergheim. While with fixed braces all teeth must first be leveled with elastic arches before teeth can be precisely moved using stable arches and elastic rubber chains, this step is completely eliminated with an aligner treatment. Since the sequence of all movements is planned precisely before the start of an aligner treatment, aligner treatments are completed around 1/3 faster than conventional treatments. At the beginning of the treatment, all the aligners required for the treatment are already produced, which means that the check-up appointments can be arranged flexibly and do not have to take place at fixed intervals as with fixed braces. Emergency appointments due to loose brackets or annoying wires are also completely eliminated.

Transparent splints like those from Invisalign are a clear alternative to fixed braces. Your treatment with aligners consists of a series of several removable aligners that you change weekly. Aligners are thin splints that cover your teeth like a second skin. You can easily remove your aligners to eat and brush your teeth, so there are no restrictions. By changing the aligners every week, the teeth are moved bit by bit into the final position that your specialist in Bergheim has planned for therapy. An aligner treatment is not only suitable for adults. Treatments for children and adolescents are also possible with "Invisalign Teen". Depending on the extent of the necessary corrections, between 7 and 50 aligners are often required. Average treatment times are between 6 and 12 months. The aligner method with Invisalign is the ideal treatment method for small, medium and severe corrections of misaligned teeth.

Compared to conventional treatment methods, aligner treatments in Bergheim are usually completed in a much shorter time and with fewer check-ups. Reasons for this lie in the exact planning by us and the treatment method.

The cost of treatment with Dr. Kirsch, orthodontist Bergheim and Dr. Lukas Mertens, M.Sc. Orthodontics Bergheim, are individual depending on the severity of the tooth misalignment.

dr Lukas Mertens, M.Sc Orthodontics Bergheim, was intensively trained by Align Technology (USA) as an Invisalign specialist by experienced, internationally renowned clinical specialists. In addition to his orthodontic work in an orthodontic practice, he worked as an Invisalign specialist at Align Technology (San Jose, USA) in an international team, further developing the "invisible" Invisalign braces. The knowledge from countless planned and set ClinCheck treatment plans to treat even highly complex treatment tasks with aligners benefits the small and large patients in Bergheim.

Over 10 million people worldwide have already been successfully treated orthodontically with the Invisalign system. This wealth of experience will also benefit you. The rail material (“Smartrack”) is unique and patented worldwide.

Pain is always subjective and everyone has a different perception of pain. Due to the precise planning with only small movements per splint, the pain is significantly less compared to conventional fixed braces.

Definitely! Orthodontic treatments are possible at any age. Aligner treatments in particular adapt well to your everyday life and are hardly noticeable to others.

Aligner treatments adapt well to your everyday life. A short adjustment phase is completely normal.
