#also night furies are one of the few species that dont lose and regrow teeth

[saturnniidae]

Headcanon: As well as the abundance of scales dragons shed, many species also lose and regrow their teeth periodically (like sharks) and it's always been tradition amongst vikings to display parts taken from dragons they killed as trophies, but now Berkians celebrate and use things dragons lose naturally. For weaponry (like how the dragon riders used shed scales for their armor) for jewelry, accessories and decoration.

Dragons have always been an integral part of Berk's culture but over the years the reasoning behind it has shifted, now they wear teeth or scales of their dragon's in pride of their beauty and the bonds they share, or for remembrance of the deceased. They put up tapestries and include them in their architecture no longer as displays of their dragon killing prowess, but in celebration of them, their nature and the peace they've made.

They're proud of their dragons, they love them and want the world to see it.
