NOTICE - Re-Registration Required!In order to make the access to our various websites and mobile app as easy and seamless as possible, we are implementing SSO (Single Sign-On). This will allow you to use the same profile (username and password) for all Delta Dental websites (www. deltadental.com, deltadentalmo.com, dentaldentalsc.com), as well as the Delta Dental mobile app. If you have already registered in the past, your account has been deleted to allow you to manage just one username and password moving forward. Re-Registering is easy!Simply follow the step-by step instructions by clicking the 'Don’t have an account?' link. **If you registered after July 1, 2017, no re-registration is necessary at this time.
