No. It wasn't checked by a vet though i've been keeping a close eye on it. It's looking really good at the moment, but if anything looks funny, i'll get mum to call the vet to check it out. The gum only got knocked a bit and the tiny amount of bleeding stop almost right away. He's now got a new bridal, so nothing more should break but from, now on, I will most certainly be checking the tack, because next time might be alot worse.
Thanxs for the concern, I will do as you say with the tack in future.
