You’ve always wanted straight teeth – so, why wait?

It’s a common assumption that a great deal of time, pain and money is needed to find that great smile – one you’ll be proud of.

That’s really not true! With the incredible technology and ongoing developments of products such as Invisalign and dental braces, it’s far more achievable than you think!


Orthodontie MC20,  is a local orthodontic practice, managed by a trusted, expert team of (smiling) locals. We love what we do, and would love to share our services with you.

We offer the entire range of contemporary orthodontic treatments in children, adolescents and adults with fixed and removable appliances – even invisible kind.
