Did you know that research has shown that some people with mouth ulcers who switch to a toothpaste without SLS (Sodium Lauryl Sulfate) will recover completely?

Anyone that has had one knows that mouth ulcers are unpleasant. It's actually an exposed nerve, which in the sensitive lining of the mouth can be very painful. The good news is they aren't contagious like cold sores so kissing isn't out of bounds but who wants to smooch with an aching mouth.

Switching to a natural toothpaste is a good first step if you suffer mouth ulcers frequently. You can get many like Lavera's mint and Green People's peppermint flavours that feel very near to a conventional toothpaste - they don't foam quite as much or have that hot tingly feeling (which isn't very nice when your mouth's cut up with ulcers anyway!) Brushing a little softer can also help.

Other causes of mouth ulcers may be stress, fungal or viral infections, IBS, Vitamin B12 deficiency, anaemia, food allergies like gluten or dairy and dental braces.

Swishing cold camomile tea around the mouth can help ease some discomfort but if ulcers haven't eased after a few weeks consult a doctor or dentist.
