Last Saturday my horse had routine annual dentist visit. This was with a new dentist and he explained and showed me where there where sharp edges and a wedge at the back teeth. Nothing major but quite a bit of rasping in the backs of his teeth to get wedges down. After filing down my horse was flushed out with some pink fluid taken from the rasp storage bucket. All fine apart from horse couldn't eat haylage but dentist explained he would be sore for a few days due to the wedge being removed and his sharp edges. If continued for 3 days then to give him a call.

Next day my horse came in from field with a massive swollen head. No heat and not pitting oedema. It was just fluid and wobbled when touched. My horse is prone to grass glands in his guttural pouches but never anything like this! It started at back of his throat and filled the gap between his jaw bone. He had only eaten half of his haylage the night before too.

His face had gone down next morning but not completely and he still only eaten half of his haylage again but I put him out as normal. At teatime fetched him in again to find his head massive again and now swelling down into his lips and chin groove. I could only just fit his head collar on.

Contacted dentist and he said not a usual reaction and he would come and see him the next night.

On Wednesday night dentist came to check inside his mouth but could find nothing other than the inside cheeks were puffy and hot to touch. The tongue was normal and the teeth were all fine and no sign of any localised inflammation or abscesses. He had never seen anything like it in his years of dentistry and only thing he could think of was reaction to the pink fluid swilled mouth out with as it was made up stronger than usual as the horse before our yard had impacted grass between teeth so to clear any infection with the stronger swill. The solution was antibacterial and alcohol solution. Can't remember the name he said.

He suggested piriton for a few days to see if allergic reaction. I decided to get the vet as it was so swollen and he was struggling to eat. He had terrible watery poo and it smelt real bad too.

By the morning it had reduced quite a bit again so I got the vets to come in the afternoon when it had swollen again.

I think it swells in the day as his head is down eating all day and on an evening his head is up eating his haylage all night so it drains away? The grass is short in the field and because mild is sweet and his grass glands where up slightly for the week before his dentistry work but nothing like this swollen!

The vet thinks an allergic reaction but can't confirm if the fluid used to swill his mouth. He was given steroid injection, antihistamine injection and antibiotic injection and bloods taken. He was eating much better the day the vet came.

Morning after the vet he was completely back to normal, apart from stretched baggy wrinkly skin and had eaten all his Haylage. He still had runny watery poo but it didn't smell like it had been.

The vet rang with blood results all normal apart from slightly low protein. She said not very low so could be down to him not eating as much over past few days and anything he has eaten passing quickly through as he has diareah.

He is now eating all his haylage every night and every morning his face is completely normal and his poo is now getting firm but with the runny fluid still. He has always been a runny bum on feed like alfalfa and other sugary feeds and rich haylage can send him this way. Up until the dentist treated him his bum was dry and had been for weeks since he had come in for the winter. He is on haylage and calm and condition and that is enough for the amount of work he does.

My worry is that his face is still up on a night when I fetch him in. He is on 20 piriton a day and 5 large steroid tablets twice a day and one antibiotic sachet a day but still getting the swelling? It's no where near as bad as when he first swelled but he is still swollen in jowl and lips with fluid on a night but completely gone by the morning?

Vet is coming again on Monday and if his protein is still low or lower then he will have to be referred to horse hospital.

Has anyone ever encountered anything like this? Vet said his heart is normal and no infections or anything just the low protein? I am unsure what it could be and dentist and vet are unsure? Is there something we could be missing that's an obvious cause? Could just the damage from over stretching the tissue in his head etc be why there is still leakage into his face during the day although no where near as bad as at start? It's just awful seeing him like this. He has been in this field over 12 months. The other horses are all fine and it is just grass he can access no trees or other plantations.

Any advise or details from similar cases would be appreciated.

Thank you for reading if you got this far!
 
this absolutely sounds identical to my horse who had an allergic reaction to danillon, hes face literally swelled over night, so much so i couldn't get his head collar on!! i dont remember what the vet gave to treat as it was quite some time ago now but i do remember it took a couple of weeks for him to return to his normal self, i fed protexin to settle his stomach which seemed to do the trick for him, mine also had low protein results, his were worrying low and i ended up feeding him a very high protein feed mix recommended by my vet, fingers crossed for you hopefully it'll just be an allergy to the liquid your dentist used and should be sorted soon :)
 
Thank you for quick reply. Sorry you have experienced the same but it does give me some comfort to know its can take weeks to clear as I was panicking that he still not right a week after. When the vet comes on Monday I will ask about the protein feed. Hopefully his protein level will be better but if not I will feed extra.

Thank you so much for the help and advice. ����
 
The vet said something like that for the name of the pink fluid. The dentist gave me the generic name for the chemical name of the antibacterial but can't remember that but if someone said it I would remember.
 
That's the one Silverfire! The dentist said he had never seen a reaction to it but as my horses mouth was tender and abraded from the work carried out maybe allowed it to be absorbed into his system? Not sure as could be so many things and just grasping at straws as to the allergic reaction.
 
TAKEN FROM WIKIPEDIA : Chlorhexidine is often used as an active ingredient in mouthwash designed to reduce dental plaque and oral bacteria. It has been shown to have an immediate bactericidal action and a prolonged bacteriostatic action due to adsorption onto the pellicle-coated enamel surface.[5] If it is not deactivated, chlorhexidine lasts longer in the mouth than other mouthwashes, which is partly why it is to be preferred over other treatments for gingivitis.[6] To treat periodontal pockets equal or greater than 5 mm

This is off a United States National Library of Medicine Website: (for humans not horses)

Forty-four (31 percent) of 140 subjects reported having AEs (adverse events). Most common were taste changes and tooth staining, sore mouth and/or throat, tongue irritation and wheezing/shortness of breath; the latter was reported more commonly before chlorhexidine use than after. Only body mass index greater than 30 was significantly related to AEs.vailable in high concentration (36%) in a gelatine-chip.

On the Equimed website:

Side Effects

While generally safe and effective when prescribed by a veterinarian, chlorhexidine can cause allergic reactions, irritation, or rash in some cases.

Precautions

Chlorhexidine should always be diluted properly prior to use to avoid allergic reactions or hypersensitivity.

Chlorhexidine should never be administered without first consulting a veterinarian.

Has he still got the wrinkled skin now? My horse has some immune thing going on and she is hypersensitive to most drugs. I stopped using hibitane to wash her mouth out (teeth probs) as I thought it may be making her mouth sore and she kept getting blisters on her lips. But any drug she has including wormers will make her mouth sore and itchy and her lips turn slightly red (or sometimes very red and blister) and she will get a lip blister. Her head has never swollen though but she does have very wrinkled skin under her throat latch and when she turns her head you can see her skin is wrinkled over the rest of her body - this is also some immune reaction. I will add a photo after of her throat.

Thanks for the info Applecart14 that's interesting about the mouth wash as the concentrate was stronger as the horse prior had impacted food in teeth so was used to swill. The ability to stay in the enamel in teeth and the tissue for prolonged period could explain why taken so long to start seeing a come down in the swelling.

My boys face was normal this morning but up again tonight after been out with head down all day but was no where near as swollen as it has been. His skin wrinkles are recovering and are barely noticeable now so think was just from skin stitching so much as his head really did get massive. How interesting Silverfire that the skin is wrinkled in your mare like my lads did. It could be an immune response my lad is having too? The vet is back tomorrow to take some more bloods so we will see what they come back as.
 
He has improved loads. He still had a slight bit of swelling around chin groove last night but no where near as bad. The vet didn't re test his blood as he had improved so much so thankfully he didn't need to be hospitalised for further tests.

He has lost quite a bit of weight due to not eating and having really bad diarreah (sp?) so anything he did eat just went through him for first week. He thankfully has dried up now so hopefully can get some weight on him. Not easy at this time of year though.

Thank you for asking how he is Silverfire. :-) x
