Fragen und Antworten
Is there a minimum age to apply invisible tooth correction?
Typically, with invisible tooth correction, tooth deficiencies can be corrected in the majority of adults and adolescents. However you should be at least 18 years old.
When should invisible tooth correction not be applied?
Only your dentist will be able to determine if you can use the invisible tooth correction.
Does this method work with an overbite?
An experienced invisible tooth correction handler can also correct an overbite in most cases.
Can I use invisible tooth correction despite having dental crowns?
Typically, single crowns do not affect the treatment with invisible tooth correction.
Can I usw invisible tooth correction despite having bridges?
Bridges connect two or more teeth together and therefore constitute a considerable resistance to tooth regulation. In this case, your practitioner must carefully evaluate whether you are suitable for a invisible tooth correction treatment.
Do I have to wear a retainer after my invisible tooth correction?
A retainer is necessary after every orthodontic treatment. You should wear the retainer according to your dentist's or orthodontist's instructions. The invisible tooth correction braces can be used as a temporary retainer in many cases. Your dentist will help to provide you with information about other retainer options.
After having used a fixed brace can displaced teeth still be corrected by a invisible tooth correction?
Many invisible tooth correction patients already had a treatment with a fixed brace before. A new displacement of these teeth can usually be restored with a invisible tooth correction.
If you do not live close to one of the 
practices in Hamburg or Munich, you can also have your dentition printed in one of our partner practices, because the quality of the print is extremely important for the production of a mouthguard. The prints influence the fit, the wearing comfort and the safety features. Our partner practices are familiar with all details of the procedure.
