Certain medical conditions and/or medications may make it inadvisable to wear braces or aligners. We always recommend that you discuss your desire for aligners with your primary care physician and your local dentist, especially if you have special health concerns. You will also be required to read and complete a SnapCorrect Consent to Treat and Medical Form as part of your aligner process. Based on your answers, our customer care experts and dental team members may contact you for more information, or you may be deemed not a good candidate for our aligners. Your health and safety is always our priority.  If you have any questions or concerns, please feel free to contact our customer support team prior to ordering your impression kit.
