Mouth ulcers: causes and prevention

If you’re like myself, and another 20% of the population, you get regular waves of irritating mouth ulcers for no apparent reason. In the majority of cases, these break-outs are very spontaneous and don’t reflect your oral health or diet, however, maintaining a high level of care for your oral health can be extremely beneficial in the prevention and reduction of ulcer appearance and dissipation.

Some of the main causes for mouth ulcers are:

  • Biting your cheek
  • Rubbing against sharp teeth
  • Poor oral hygiene
  • Oral thrush or herpes
  • Burns from hot food or drinks

The best ways to prevent mouth ulcers and reduce their severity are:

  • Brush your teeth at least twice a day
  • Floss regularly
  • Brush your teeth gently, do not use unnecessary force
  • Avoid spicy or physically hot foods and drinks
  • Avoid highly salted or sugary foods
  • Visit your dentist regularly (can help diagnose diseases and infections before they create ulcers)

If you currently have mouth ulcers that are causing you extreme pain and discomfort, visit your local GP. I also recommend Difflam Anti-Inflammatory Gargle in the meantime, as it will soothe the pain and numb your ulcers. You can purchase it here:
