So sick of mouth ulcers

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.

The SLS in some toothpastes can give people mouth ulcers. Might be worth chucking a multivitamin into the mix as well. It is really annoying though, I used to sometimes get 10-15 at a time during my worst phases. I took to painting them directly with medicated mouthwash on the end of a cotton bud.

Another vote for coeliac testing!

I was literally just sat thinking how much I I hate being prone to mouth ulcers when I saw this thread. Every single time I break the skin in my mouth, no matter how slightly, I get a huge and very painful mouth ulcer. I’ve had this ever since I was a child. I’ve had bloods done, been tested for coeliac and IBD, nothing has ever come up. It’s so frustrating, I hate them

Have they checked for
Coeliac ?

They are awful. You have my sympathy OP. Get some bonjela on them as soon as you possibly can when they still in their early phase.
I see you are already using Sensodyne (many other toothpastes trigger ulcers for me).
i’m assuming you’ve been checked for Coeliac disease?

folate or b12 deficiency?

At the first hint of a mouth ulcer, I take two Lysine tablets and within hours it has gone.
I buy mine from Amazon, but be warned the tablets are big! Nothing is as effective for me, I swear by them.
Also good for stopping cold sores, if caught early enough.

I used to get them terribly, like 15 at a time, and they would take 10+ days to go away. They always seemed to come and go in time with my menstrual cycle too. Turned out my folate levels were very low and I was given tablets. Now I only get one very occasionally and usually when I've managed to bite the inside of my cheek or banged my lip against my teeth.

Maybe you could get the gp to swab the ulcer when it’s bad in case it’s a kind of herpes that keeps coming back. (There’s quite a number of types of herpes I understand). They could send the swab off for testing.

when’s the last time you had bloods done? It sounds like you are really run down.

if you get bloods taken, something easily treatable could be picked up and sorted, like iron or folate or somwthimg. i’d defo look into it.
