You should always be up to date on your dental health check ups. Most dentists recommend a check-up every 6 months.  A check-up usually includes x-rays, an examination, cleaning, and evaluation of your dental health. Your dentist will let you know if any dental work is recommended, and if you have any possible dental issues. This evaluation is important for making sure that you are ready and eligible for an aligner treatment. Feel free to discuss your options for braces or aligners with your dentist. She or he will let you know if you have the dental health required for safe treatment. We also ask you to sign a Consent to Treat and Medical History Form, to make sure you have covered these aspects with your dentist. If you have any dental work that needs to be addressed (like cavities or extractions), you should take care of this before you do your impressions.
