In 7000 BC any type of tooth related disorder was solved by bead craftsmen using blow drills. This strategy used in the Indus Valley Civilization, drilled holes in your teeth (most likely molars) with the same equipment used for woodworking and creating fires. The blow drills used were all man-made contraptions that required physical forced to rotate quickly, creating plenty of friction and release of heat which eventually creates a hole. This process was relatively slow causing much pain. On the bright side, this treatment yields to effective results.
In 7000 BC tooth fillings consisted of beeswax. Researchers in Slovenia found a person's jaw in a cave with lumps of beeswax which is why scientist believe beeswax was an attempt to fix cracked teeth. Beeswax for the most part sealed the hole in your tooth but did not offer a good fix, so we should stick with the composites our dentist know and love today, and leave the beeswax for cracked lips.
