Restoring a tooth with a discoloration in the aesthetic zone is only a challenging situation. If more conservative treatments like internal bleaching don’t work properly it is possible to mask that discoloration with an opaque resin and then cover it with a body opacity. The new and modern composite resin materials allow us to work with simplicity and in an easier way. This new composites have some specific opaque resins that allow us to mask the tooth and then give back the final color with just one opacity.

Conclusions
New dental materials are available in the market and they could solve difficult aesthetic cases with simple and conservative way. In this article a new white opaque resin composite was placed to cover a hard discoloration which is difficult to manage without making a crown. The knowledge of new technology and materials allows to have a best aesthetic results preserving as much dental tissues as possible.
