It’s always mice. Scientists in laboratories across the globe have been mutating mice for decades. Millions of mice at this point have been lost to the scientist’s inquisitive hand – what with growing ears on their backs, and now genetically reproducing their “dentin”. Dentin, dear reader, is a structural layer of the tooth (enamel, dentin, pulp on the inside). British scientists have developed a chemical that “encourage(s) cells in the dental pulp to heal small holes in mice teeth,” according BBC News.

The application of a drug the scientists are calling “Tideglusib” reacted with “stem cells in the pulp (of the mice)”. Referring to tested cavities, the report continues, “a (Tideglusib)-soaked sponge was placed in the hole and then a protective coating was applied over the top. As the sponge broke down it was replaced by dentine, healing the tooth”.

What they’re essentially saying here, is instead of filling the tiny mouse cavity with a metal or a composite, they soaked the smallest sponge know in the land in the chemical they developed, and packed it into the hole. As it soaked into the gums of the little mouse, the chemical forced a reaction on a cellular level, producing actual tooth dentin within the cavity. And my brain, on a cellular level, just produced an explosion that melted it inside my head because it couldn’t handle the science.

Does this mean instead of forcing Novocain into your maxillary roof with half the doctor’s meaty mit jammed into your mouth – that he’ll just paste a wet sponge into your molar and call it a day? If so, then yes. Point me toward the Swedish Fish. Can you even imagine childhood without fillings? No numb drooly mouth? No jaw-wedge? No drilling or filling or clamping or grinding? What would a childhood even be without fillings?
