A problem when jumping!

[RuthP]

My mare loves jumping and often goes quickly into fences. When I try to check her to slow her she sometimes throws her head up very high. She's actually knocked my teeth out a few years ago doing this which is why I have avoided jumping for a long time.
She's very well schooled on the flat and I try to be as relaxed as possible when jumping, I put trot poles in front of the jump and mainly jump from a trot at home (the problems mainly when we're out jumping).
I want to try to solve the problem with schooling but I think its more a case of too much enery and too much excitement (she has a handful of chaff and balancer for her feed), rather than a schooling problem (hope that makes sense).
She's ridden for jumping in a dutch gag with a french link (middle ring) and a running martingale- does the martingale need shortening?
Any schooling or bitting/tack suggestions greatly appreciated.
Thanks

This might not help, but with my green horse I made him go up to the jump at canter but circled away from it, and didn't actually jump anything until he could canter steadily towards a jump..The first few times she might throw her head up, but keep your leg on and push her forwards.

Put a jump out but with the pole on the ground and then canter round and over it with her on a fairly loose rein, if she wants to rush let her but just keep going round sitting quietly and not fiddling with the reins untl she goes nice and steadily without changing pace, then put the jump to a teeny (6 inch) cross pole and repeat until again she is not rushing just let her canter round at her own pace and don't attempt to slow her or check her. Keep doing this until you have a reasonable size jump and then repeat this lesson a few more times starting the jump a little larger although if she rushes it go back to the pole on the ground. The idea is to make her realise that it is easier to keep a steady pace than to charge at the jumps.

if she is able to smack you in the face, then I would guess your martingale is too long. If you are sure it's nothing you are doing wrong, you could also try a market harborough. This worked well on my lad.
