They were right - the teeth are placed in a special container and then disposed of. What else can you do with your extracted teeth? I don't think they can be good for anything, although who knows ... But I heard from a dentist friend that they are simply disposed of in containers, and not just in a bag and in a trash can. :)))
Throw it away, of course!
In special containers, dead teeth are taken from dental clinics to specialized recycling facilities.)
That's how it is.)
