Lifestyle Modification

Minor trauma from poor-fitting dentures, rough fillings, or braces can aggravate mouth ulcers and should be remedied by a dentist.

A few reports have found sodium lauryl sulphate (SLS), a component of some toothpastes, to be a potential cause of mouth ulcers.1 In one trial, most recurrent mouth ulcers were eliminated just by avoiding toothpaste containing SLS for three months.2 Positive effects of eliminating SLS have been confirmed in double-blind research.3 SLS is thought to increase the risk of mouth ulcers by removing a protective coating (mucin) in the mouth. People with recurrent mouth ulcers should use an SLS-free toothpaste for a few months to see if such a change helps.

Measurements of stress were associated with recurrent mouth ulcers in one preliminary study,4 but not in another.5 More research is needed to determine whether stress reduction techniques might reduce mouth ulcer recurrences.
