Is anybody there :(( dont really no who I can talk to my dad is struggling feels his new tongue is to big and also his teeth don't join so feels it's not right x we don't think he can swallow as all his saliva is just sitting in his mouth

so the doctors think he can't swallow ? Can this be learned x there's no speech at all only noise and he doesn't open his mouth or breathe through it only his nose but now I'm worried if he gets a cold then what ? So many questions and nobody to ask :(( x
