My Rebel is 2 years old and has this condition. It is rare, and my vet conferred with UGA vet school before telling me Rebel has it. I took him in for a cleaning and he came out minus 9 permanent teeth in Feb.
Rebel had gotten the injection that's supposed to help his teeth, but I won't put him thru that again - it was very painful for him.
I have to be careful to keep his teeth brushed and when we play, I never pull very hard on his toys with him. There is no "cure", but regular cleanings and oral hygiene can help him keep his remaining teeth.
I've had several health issues with him since I got him - including LP surgery when he was 8 mos old and tried to contact his breeder. She responded once and basically didn't care. She doesn't respond anymore and I didn't even try to contact her when I found out about Reb's teeth. I just feel sorry for anyone who buys from her. She charges for healthy pups, but doesn't deliver. (She isn't a YT member BTW)
Good luck to you and your little angel.
