I am writing this in the hope that someone may have a similar experience but I appreciate any idvice/ideas that anyone may have. Please bare with me this may be quite a long post but I want to give you as much info as possible.

Earlier this year, around March time, after having previously had no problems at all with teeth/eating etc my 19 year old mare started having the odd reaction to her hay now and again; either moving sharply away, rubbing her face or being in obvious pain when chewing. We had very recently (just days earlier) had teeth checked when this started so originally thought it was something to do with the hay rather than teeth (nothing was abnormal during her tooth rasping - and think the timing was a total coincidence). As the problem became more frequent and it became clear it wasn't the hay that was the problem we had her teeth checked again, but no problems were seen.

She did, and still does have some diastemas (small gaps) that get food stuck but these have never been a problem before, have not been infected and are not believed to be the problem - have tried cleaning them regularly, filling them etc but this made no difference. On vets advice we turned out 24/7 from this point as she could manage grass and we thought leaving her to just graze over summer may give the 'problem' time to heal/fix itself (it was worth a shot money wise as we are not insured for this sort of problem so funds sadly have to be a factor).

All fine over summer, teeth checked again about 6 weeks ago, all clean and fine. I soon after this started giving her small net twice a day as grass is becoming limited (she is still out 24/7 but although a good do-er does require something on top of this and she will soon be in at night - yard rules). All fine with the nets for a couple of weeks, and I watched her like a hawk, but all has gone wrong again since I had to bring her in for two nights last week as the weather was foul and everything else was in. She ate up from her hay bar both nights but when I went back to the tea and breakfast nets she started showing the same symptoms as before. I took hay off her as soon as I realised she was in pain and called vet who also brought along another vet who specialises in teeth for her opinion but- as before, no obvious signs in her mouth, no changes of any kind.

But there obviously IS a problem - and I feel at a total loss. Both vets that saw her last week believe it must be a sensitivity of somekind, probably related to the diastemas but not directly caused by them.

What I don't really understand is why she was okay for 2 weeks on small nets but after two nights on larger amounts the pain has returned, and also why it is only hay that causes it? And also, I don't know what to do in terms of feeding her now. I have not given hay since, she has been on fastfibre instead but i don't really want to see hay replacers as a long term solution if possible. This is partly because of cost, partly because of weight management (lami prone type), partly as she will become bored (and can be fussy) and partly as from experience she will eat it too quickly to last the night as she thinks it is just a feed. Also I am aware the turnout 24/7 all year would be ideal but this is unavailable at the yard and I am not in a position to move at this time.

Vet has suggested that other options to hay replacers mixing hay with chop so she doesn't get large mouthfulls of hay at once, or tiny holed double nets for the same effect - but this still worries me in case she does still get pain and ends up eating nothing over night, but perhaps I am wrong? Does anyone else have other suggestions/thoughts/experiences, both on the problem itself and on how to feed?

So sorry for the essay of a post, and thank you if you have read this far. And appologies if I have missed out any info, I wrote this post once and manged to lose it so this my second attempt!

I wonder whether it is her jaw that pains her rather than teeth ( the side to side grinding action) did vets manipulate her jaw to see if teeth are grinding / moving smoothly with this action? Maybe worth getting a proper equine dentist out rather than using the vet?

Surreydeb I did wonder this too with the pain only coming on after a while of having hay, but if this was the problem would you expect it to be there all the time rather than so intermittently? And would you expect feed, long grass etc would also cause paint? I will ask my vet about this possibility and I may get a second opinion from a dentist, we have seen 2 since the problem began and I have found my vet more helpful than either of them but another opinion couldn't do any harm I suppose.

Crabbymare she is 19 and yes, we've tried all types of hay/haylage/soaked etc, we are fairly certain that the problem isn't with the feed itself.

Could you try her on some Horsehage (ryegrass) for a week and see if she has any problems with that. I know hay can be very dry and stalky and cause problems.

With her grazing ok & eating from the haybar ok is it possible its something to do with the stance of eating hay? Eg she is fine head down in a natural grazing stance, but not head up & eating from a net. Or something to do with the tugging action required to get hay from a net, which isn't required for grass or haybars. Or a combination of both. Easy test would be to see if she'll eat hay straight off the stable floor. If that is it, I'd be thinking its more of a neck, back etc problem than her mouth. Other option is an abcess right at the root, where it would be invisible to vets & edts.

She was on haylage last winter when the problem began - it is only this year we have started hay (we usually avoid as she coughs if not thoroughly soaked and its a complete pain in winter - but vet suggested that as it was shorter she may chew it more easily than haylage).

Now I think about though it we did try 1/2 Horseage 1/2 fast fibre/just grass just before she started going out 24/7 in spring, although I can't exactly remember why but it may have been due to weight gain from the hay replacers and out of interest to see if there was any improvement from cleaning diastemas. From my memory I don't remember any negative reaction but that may be conincidental, but I may see if someone on the yard has any I could try. Thanks for that suggestion, it is provoking a few memories that may prove helpful!

Hay etc is tougher to eat than grass and feed so jaw may be ok with those? I know when I had a very old horse she just couldn't chew hay could manage soft haylage though. Have to chew harder with dry stalky stuff if you know what I mean and may aggregate a problem. I agree with another poster may also be a neck problem and position of feeding - worth trying feeding hay on the ground and see if same reaction.

Littlelegs, we have tried this too as it has been something someone suggested in the past but she still moves away from hay on the floor or in the hay bar and looks pained when chewing and has refused to eat it at all many times in the past so I don't think this is the problem. Physio has also seen her and not found anything unusual, but thank you for the suggestion.

I will deffinately look again at feeding a soft haylage or horsehage as was suggested, as this is similar to what she was being fed when the problem originated I have not thought about trying it again since but perhaps its something i've overlooked.

I will also talk to vet and physio about her jaw, neck etc as I want to rule out all posibilities, even if they have been checked once I know things can be missed.

Thanks for all the suggestions/help so far x

HI - I'm wondering if your horse has equine TMJ (or TMD) issues.

I have the human version of TMJ and now going down the root of a TMJ specialist (have already done the dental route who specialises in TMJ not your basic dentist). I would speak to a highly/fully qualified equine dentist who actually understands equine TMJ. Good Luck and keep us informed.

There was a previous post a while back re. equine TMJ or TMD but the search button is not working at the moment.
