A note about toothpaste

I wondered if this might be helpful for anyone else. I had been having a lot of trouble recently with sores in my mouth and little ulcers. I kept blaming this on my teeth which have become so thin with age and wear that they are razor sharp. However, I read somewhere that toothpaste with sodium lauryl sulphate can cause such problems. I have now switched to a SLS free toothpaste and am pleased to say that the problem seems to have disappeared.

I had a friend who had a problem with sodium lauryl sulphate as well. It is the foaming agent in many products. As I occasionally have the same problem, Nandalot, which toothpaste are you using now?

We use Kingfisher - there are lots of flavours and most of them have added fluoride which is good!!!

Thank you kittylester

That’s a good thought about specific ingredients causing a problem, thank you.

But check the ingredients as some kingfisher pastes do have sodium laurel sulphate in them.

That’s very interesting. It has made me think of the chemicals we are putting into our mouths so I am going to buy toothpaste from our local health shop which I’ve been meaning to do anyway.

We buy our Kingfisher from Amazon.

I buy toothpaste, and many other hygiene and skin care products from Holland and Barrett.

I cannot use Corsodyl in any form. I am violently allergic to its special ingredient. My dentist recommended to wash out one side of my mouth with it, after an implant. my face swelled like a balloon and I had a huge bruise along the jawline of that side of my mouth, An acquaintance thought I was a victim of domestic violence. She didn't say so in so many words but the careful direction of her comments made it clear what she thought., which considering she knew DH, I found quite upsetting. In the end I showed her my new implant and the redness round it.

I have changed to Sensodyne pronamel.

SLS is the foaming agent in toothpaste and it’s very common that it can irritate soft dental tissues, especially gums and the inside of cheeks . As well as ulcers , it’s implicated in Lichen Planus and Burning Mouth Syndrome. I tend to recommend Sensordyne pro enamel as it’s sls free but still has fluoride which is good for sensitivity.

Yes, I use that one usually, not always.

As a hygienist, I’m not a fan of Corsodyl , you should only use it for 2 weeks max . It’s designed for short term use , post surgery or infection and it stains your teeth . Plus there has been a few deaths from anaphylactic shock .

I remember seeing my doctor years ago about the fact I kept getting bleeding in my mouth and I started using toothpaste without sls.

Thats interesting, because when I had my severe adverse reaction to Corsodyl, my dentist told me he had never seen an adverse reaction to the product until I had one.,

Not forgetting many shampoos also contain that dicey ingredient. I was surprised at just how many - cue for I had to throw out the one I was using....

I gather "Faith in Nature" is a reasonably priced one that hasn't got that ingredient...

HelterSkelter1 Tue 09-Dec-25 10:30:43

I have must looked at my bottle of Fsith in Nature shampoo and it contains ammonium lauren sulfate. Is that different? Anyone know?

grandMattie Tue 09-Dec-25 11:36:57

Im another acidosis user. Its flavour has changed,it used to be salty. DH would rather not clean his teeth than use it! 😆

grandMattie Tue 09-Dec-25 11:37:27

I’m an other CORDOCYL user.. grrr 😡

justwokeup Tue 09-Dec-25 12:03:58

A pharmacist absolutely refused to sell me Corsodyl toothpaste, said it was far too strong. My hygienist last week advised me to put Corsodyl ointment only on a teepee to target gum sensitivity but absolutely nowhere else and not use it for longer than 5 days.

Kimski44 Tue 09-Dec-25 14:00:06

I’m using Zing now. Being in the UK, I do make sure that toothpaste contains fluoride but apart from that it doesn’t contain sls or titanium dioxide as far as I remember.

I mean, then how mad is it that this is put into toothpaste!
Somewhere there is a level of commen sense missing.

Oh this ingredient 'can irritate soft dental tissues, especially gums and the inside of cheeks'. I know! Lets out it in toothpaste! angry confused tchhmm

justanovice Tue 09-Dec-25 14:19:27

I also have a problem with SLS and have changed not only my toothpaste but also my shower gel and shampoo with a resulting and noticeable improvement in my skin.

Robin202 Tue 09-Dec-25 14:38:14

I use Aloe Dent - a natural toothpaste minus the Fluoride which we all know now is bad for us.

Clematis46 Tue 09-Dec-25 14:41:28

I remember the greatly missed Michael Mosley promoting sls-free toothpaste for those who suffered regularly from mouth ulcers. I’ve used various Sensodyne products ever since and have far fewer mouth ulcers.
