This is a common occurrence with all orthodontic treatment, but is one that can easily be overcome. Wearing retainers after traditional braces or Invisalign treatment means you are keeping your teeth in their new position and protecting your smile and investment. Clear retainers or Invisalign Vivera retainers are custom made for you with a state-of-the-art technology from an impression or scan of your teeth, and you will benefit from a precise fit and therefore more comfortable fit.
