A free mod for Dragon Age, by Brumbek.

Realistic Teeth is an add-on for the Dragon Age: Origins game that allows you to change the appearance of your characters’ teeth. It is a very easy and intuitive addon, and you don’t have to do anything special to use it. All you have to do is open the application, and you will be able to change the appearance of your characters teeth in a very easy and intuitive way. This addon works perfectly with the original Dragon Age: Origins Campaign. However, faces (.mor files) not specifically created for my mod will NOT retain all their unique appearances while using my mod! All the facial structure settings will revert back to the default appearance. However, all hair, colors, tints, and materials settings will work.
