I am always looking for excuses to not brush my teeth, but the dentist always threatens me with painful cavity fillings. Well, screw you, dentist! With new tooth regeneration gel, I no longer have a reason to brush.
The new gel could completely eliminate fillings, instead placing this in a cavity and regenerating the tooth over the course of a month or so.
Tests have shown the gel working on cavity-filled mice teeth, and human trials are due to start soon. Sure, it'll be several years before this stuff shows up in dentists' offices, but I'm going to be proactive and throw out my toothbrush now. [Discovery via Kottke]
