Early Dentistry In India

Brahmin - Rajan, I would like to perform Kanyadan, so I need lots of wealth. I have heard that you are a great daanveer. What will you give me?
Karna - take, whatever is left in my chariot.
Brahmin - there is nothing left in your chariot besides your weapons.
It was night time and thieves were stealing things from Karna's chariot.
Karna - I do have gold in my teeth that I can give it to you.
Karna took a rock and smashed his teeth and gave it to the Brahmin. ( When taking Kavach and Kundal, Karna had to feel great pain. At this time, he also had to feel great pain by trying to smash his teeth with a rock. )
Brahmin - that daan came out of your mouth so it is dirty. You will give me a dirty daan.
Karna - Bhudev, you are right. Can you give me water so I can wash it and give it to you.
Brahmin - Look in this battlefield, there is hardly anyone. Who will give you water. Water is more precious than the gold that you have in your hand.
Karna - Bhudev, you are right.
Karna was wounded so did not have much strength left. Karna could not get up so slid on the ground and got close to his chariot. Karna grabbed the wheel and got on the chariot, where he saw his weapons. Karna took his weapons and slid on the ground where the Brahmin stood. Karna placed an arrow on his bow and shot the arrow by placing Gangaastra mantra on it.
( In Jaimini, the curse was not forgetting divine weapons but falling in the battle on the second day )
River Ganga appeared and Karna washed his teeth in it. Karna donated his teeth to the Brahmin. The Brahmin smiled and turned into Lord Krishna. ( Karna had asked for a boon for Krishna, long time ago to give him darshan at the time of his death. ) Krishna showed Karna his Viswa swaroop. Karna was very glad and fell at Lord's feet.
Krishna - You are the greatest daanveer I have seen. Ask for anything that you wish.
