So sick of mouth ulcers

87 replies

giddykipper3 · 17/05/2026 16:15

I get one maybe once a month or every other month. Sometimes mild, sometimes severe like the one I’ve got now. It’s not just the localised pain it’s the headache, fatigue and raised glands - my body is clearly fighting it and that takes its toll. I’ve tried everything - only use sensodyne toothpaste, use anti bac mouthwash, all the topical treatments you can buy. I had a full blood count done 6 months ago for something else and they all came back normal.

My dentist referred me to the hospital last year and they were very dismissive. Basically just said some people are susceptible to them and I should work on my stress levels 🙄

When I don’t have one I kind of forget how bad they are. But then I get a nasty one like I have on my inside cheek at the moment and I feel rotten for a week and think I can’t carry on with this. It’s been happening on/off for years.

Get acyclovir tablets from the gp.

giddykipper3 · 31/05/2026 22:47

Sorry to resurrect this thread but I am suffering once again and have been for the past two weeks, no sooner does one clear up then another one arrives. This time right on my soft palate making it hell to eat anything. I’ve finally ordered some Lysine tablets off Amazon - does anyone have any experience with these? Also going to request bloods with GP as this can’t be normal.

Get acyclovir tablets from your gp. One a day and you wont have any more ulcers

Lookingatabookshelf · 18/05/2026 21:38

I also think take iron (ferrous fumerate), folic acid b12 and vit D for a month. You don't need blood tests first just try them and see if they help. If they do then you might need to see why you are low in them (celiacs can be a cause) My husband had terrible ulcers in the corner of his mouth and cracked sore tongue turns out the lanzoperazol he takes reduces absorption of vitamins and these were causing the problem.

Itsthisyearisntit · 18/05/2026 21:02

I know how you feel, I have an enormous one on the inside of my cheek at the same level as the edge of my teeth. It’s been there now for 11 days and shows no sign of going. It’s making eating difficult as well as brushing my teeth.
I usually get a cluster at one time so I am just waiting for the next ones to appear.

I have suffered with mouth ulcers my entire life so I completely feel your pain, they’re horrible. I was referred to a consultant and after the usual investigations revealed nothing, I was prescribed prednisolone soluble tablets to rinse my mouth with and they’re the best thing I’ve tried because they don’t numb the pain, they heal the ulcer (and I’ve tried everything). Another thing that works is a brown steroid inhaler as technically it’s the same medication as the mouth wash, sprayed directly on the ulcer, heals it super quick! Often overnight if done at the first sign of one coming.

For pain relief, rub a paracetamol tablet directly on the ulcer, that takes the pain away better than bonjela and all those of gels that don’t even touch the sides!

Tiredbarbie · 18/05/2026 20:56

Vitamins.
Try to track any foods that trigger - for me it’s often in sweet food, terrys chocolate orange (sob) and certain flapjack type bars. No idea why!
When you get them - use difflam rinse regularly. Absolutely saved me when I had hand, food and mouth.
mine also cycle related. They are hideous.

Mskittenheels · 18/05/2026 20:49

I know it’s not the same reasoning but I used to get them when I had braces and the thing I found was difflam throat spray to numb them and difflam mouthwash to treat them. But if yours are related to mental cycle as opposed to friction (rubbing on teeth / braces) might be a different thing but solidarity OP they are awful and affect every area of your life.

AzureLurker · 17/05/2026 23:56

I used to get major apthous ulcers, easily get to a cm across and last for several weeks at a time. Horrendous pain that no-one can understand these are not regular ulcers. You used to be able to get a steroid ointment from your dentist but they stopped making it. Only thing that worked for me until I found out I had dairy, yeast and benzoates allergies and gave all that up. Only used to be able to use McLeans toothpaste but can use some colgate versions nowadays due to the benzoates. I only get the odd one now from trauma like you say but not always. I could add a picture but nobody wants to see that! You can buy Orabase ointment online and crush up a tiny bit of steroid pill if you have any lying around, but I didn't say that.

chocolateorange03 · 17/05/2026 21:53

@giddykipper3solidarity, no advice really but I'm in exactly the same situation as you, it's so disheartening when they come back within a week or 2 of them going. My new doctor has said I should take a daily vitamin c, but also said I have oral thrush, so im 2 days in with antifungals and vitamin c, really hoping it makes a difference, i doubt it though, I'm so unbelievably fed up!

eyespartyparty · 17/05/2026 21:48

My dentist advised me to never use ‘normal’ mouthwash but when I have an ulcer to use this one ‘Curasept’ you can get it from Amazon or the dentist.
and it works very well to get rid of them. Yours do sound out of the ordinary though, if it’s causing a lot of pain on top. Might help for a short term help though, not too expensive so worth a try maybe.

Malbecfan · 17/05/2026 21:46

This is going to sound really odd but sage is brilliant for easing mouth ulcers. Either hold a leaf on it for as long as you can, or if you only have rubbed sage (the small bits in a herbs jar) steep a spoonful in boiling water for a few minutes then when it’s cool enough, put some of the bits of sage against the ulcer, again for several minutes.

I taught a youngster who was on strong medication for something unpleasant; a side-effect was horrific ulcers. She was in despair. I suggested sage to her. A week later her mum emailed to thank me. It didn’t interfere with her medication, didn’t taste too bad and actually worked. If nothing else, it’s cheap and easy to use.

Mummybearsthename · 17/05/2026 21:41

Could it be food related? My son has orofacialgranulomatosis and gets mouth ulcers from benzoates.

I hope you find the cause and can prevent them...they can be really nasty.

giddykipper3 · 17/05/2026 21:36

I’m not sure if I’ve had thyroid checked. I’ve lost track to be honest. Probably not though. I kind of thought when I got the hospital referral they would cover all of this but they were so blasé about it. Not helpful at all.

Im just sick of losing weeks of my life to it. That’s dramatic, I can still function and go to work etc. But just know as soon as I get a bad one that it’ll be at least a week of feeling below par, generally unwell and knackered while my body fights it off. I manage it with paracetamol until I wake up one day and it feels like the headache has lifted and the pains reduced bit and from then on it gradually heals. But god it’s vile at the height of it. Right now it’s a huge cheek ulcer that is also radiating pain to my throat and ear along with headache and fatigue.

Have you had your thyroid and b12 checked? Vitamin D too. I had constant mouth ulcers and scabs in the corners of my mouth when I was low on b12/vit D and my thyroid was hypo.

It's really easy to check and fix but makes you feel so awful.

Found a few things saying low zinc was linked to mouth ulcers online

A lack of zinc in your diet can also cause recurring mouth ulcers. Several studies have shown that low zinc levels can increase the risk of mouth ulcers and patients with low zinc levels in their system often suffer from recurring mouth ulcers.

user1492538376 · 17/05/2026 17:48

How old are you? I used to get them a lot when I was younger but much less at 39. I think sometimes it hormones and period but also genetic.

I used to get a steriod cream from the doctors.

MandarinLime · 17/05/2026 17:46

I found multivitamins with zinc worked for me. I had about 10 after my wedding. I'd been dieting and got run down.

PermanentTemporary · 17/05/2026 17:44

You’ve clearly checked the nutrition side but when I used to get them I would have marmite on granary toast for a few days in a row and that seemed to help.

dontcallmelen · 17/05/2026 17:40

I feel for you OP I get them fairly regularly usually when my folate levels are low (I have regular bloods done due to meds I’m on) once I restart the folate very rarely get them, I find ambesol more effective than Bonjela.

Double check that the Sensodyne you use is SLS free. Not all are.

Gentle whitening is one of the few that is sls free. I suffered with weekly ulcers from a pre teen until my mid 30s. Found out about sls and initially turned to welleda salt based toothpaste and then gentle whitening about 10 years ago, I now get one or two a year when I used to have 3 or four constantly (including regular tongue ulcers which were agony!) it's not a fix for everyone but should be one of the first courses of action for people prone to them is an easy first attempt to fix.

FortyFacedFuckers · 17/05/2026 17:38

I get them related to my cycle as well, literally nearly in tears with them right now, feels like my full mouth is covered in them.

1lov3comps · 17/05/2026 17:13

I take lysine every day and mine have reduced massively since I started, I still get them
nut far less regularly and they tend to be less intense

Helpforsummer · 17/05/2026 17:05

This is going to sound out there, but desperate times and it'll cost nothing to try...
A girl I used to work with got them terribly, she started putting her toothbrush away in a cupboard after use. She stopped getting them.
