The cost of orthodontic treatment for an adult is not necessarily more expensive than for a teenager, but depends on the complexity of the problem. Many adults prefer to wear invisible braces (aligners): this solution generally does not significantly increase the cost of treatment. Unfortunately, however, it cannot be applied in all cases. It’s best to consult an orthodontist for a precise estimate, as each problem requires its own specific treatment. Only an orthodontist will be able to make a treatment proposal and give you a quotation once a full diagnosis has been made.
