MDDS is switching to a dual login process. Please follow these instructions carefully. For ADA Members, you will log in using the ADA Member Login button in the section immediately below. For all others who are not ADA Members, you will use the NONMEMBER Login section further down which has a ‘username’ and ‘password’ field.

IF YOU ARE AN ADA MEMBER that previously logged in directly to our website, you may need to log out first so you can start to use the ADA Member Login button.

This is where ADA Members log in. This button takes you to the ADA Portal where you’ll log in. After logging in, you will automatically be redirected back here.
