Scientists have found a pre-historic tooth with a filled cavity.
The tooth belongs to a 6500 year old fossilized jawbone of a young person. This jawbone was found almost 100 years ago in the European country of Slovenia.
On doing an X-ray on the jawbone the scientists discovered the tooth filling which seems to have been made of beeswax.
Guess who was taking care of their teeth even before the beginning of dental care :)
