What's the cause of mouth ulcers?

[hillbilly]

I have got some mouth ulcers which are really painful. Does anyone know the cause?

Being stressed and run down can cause mouth ulcers.

acidic wine, boiled sweets..

stress? try hot salty mouth washes. try and keep it in as long as poss and do regually.

Zinc deficiency?

bonjela...get some

Usually it's a virus and it can get the better of you when you're stressed or run down or as part of PMS. Been looking for a proper treatment or cure for 25 years... the most helpful for me was to give up sugar and ordinary toothpaste - it drastically improved when I started using herbal toothpaste. Hope it improves soon for you.

Most 'normal' mouth ulcers are caused by some kind of trauma/ damage to the mouth (knocked with toothbrush/ sharp food etc). Ordinary ulcers are not viral. See here for some info.

I get them when I am run down. I have found something called Iglu (over the counter) which works really well. It is like a paste that sticks on and protects and heals - much better than anything I have ever tried.

being anaemic can cause them too

Thanks everybody. It's very unusual for me to get them. I have some bonjela which stings like hell!
