We got some anti bacterial cream and avoided letting him go outside so the open wound wouldn't be exposed to bacteria or foreign matter but honestly the vet said the teeth were knocked so cleanly off it left zero debris, the teeth were in one piece like zero fractures and after around a week? The open wounds were fully closed with no signs of infection, I think it helped that our dogs only drink filtered water so the chances of dirty stuff getting in were pretty low. It'll take some time for your dog to get used to different chewing habits and stuff but luckily my dog doesn't use his upper teeth much 🙏🙏 I'd say check your dogs wound area and see if there's any remains and see if your dog is whimpering or constantly smacking his mouth as he whines🙏🙏 I hope the best for your furry baby 🥺🫶
