So I have a 6 1/2 year old boar. He got a filling done for his two incisors (top and bottom) he does have a dental disease and he does have a heart condition. After the vet finished his teeth procedure. I noticed that he might be drooling? And every time I feed critical care he does this gagging motion as if he wants to throw up. I also noticed that his bottom incisors are too sort. It looks like he doesn’t have his bottom teeth, it’s there but not visible. So anything I can do? He is loosing weight for not being able to eat. And I hate it when he gags during the time in trying to syringe feed him. Any help please and thank you!
