If you have crooked teeth and/or a misaligned bite (an underbite or overbite), there are a variety of treatments that can help straighten teeth, including braces and retainers.
The dentist will ask questions about your health, conduct a clinical exam, take impressions of your teeth, take photos of your face and teeth, and order X-rays of the mouth and head. An appropriate treatment plan is made based on analysis of the gathered information.
In some cases, a removable invisible retainer will be all that's necessary instead of a ceramic option. In other rare cases (especially when there is an extreme overbite or underbite), surgery may be necessary. In most cases, however, braces will be needed, lingual or traditional*.
* Any surgical or invasive procedure carries risks. Before proceeding, you should seek a second opinion from an appropriately qualified health practitioner.
