Mouth Ulcers – Mouth Sores

mouth ulcers

Mouth ulcers are very common. They are painful and uncomfortable sores that can appear anywhere in the mouth. But are most often found on the tongue (tongue ulcers) or inside the mouth. They are usually round or oval in shape and appear raised and swollen. Mouth sores can be red, white, yellow, or gray in color.

You can have one or more mouth ulcers, and they can be very tender and painful, making eating, drinking, or brushing your teeth uncomfortable. Fortunately, there are treatments for ulcers that you can follow at home that help them to disappear faster and prevent them from reappearing.

What Causes Mouth Ulcers?

Most mouth ulcers are usually caused by damage to the lining of the mouth, as a result of one of the following factors:


  • Biting your cheeks or tongue
  • Poorly fitting dentures
  • Hard, crunchy foods that don’t break easily
  • Sharp teeth or a faulty filling
  • Other possible causes may be stress, family history, or eating certain foods that can cause ulcers, such as nuts, cheese, spicy foods, or wheat flour.

Remedies for Mouth Sores

Mouth ulcers usually go away on their own in about a week. If they bother you, you can try one of the following methods that can help speed up the healing or help stop them when they reappear:

  • Use an antimicrobial mouthwash, such as Pardontax Extra 0.2% mouthwash. This will not prevent mouth ulcers from reappearing, but it can inhibit the growth of plaque.
  • Too much force in brushing can damage the gums and lead to an ulcer. Ask your dentist which toothbrush is right for you.
  • Avoid crunchy, spicy, acidic, hot, or salty foods until the ulcer heals.
  • Avoid trigger foods that you find to give you ulcers.
  • Although most ulcers are harmless, if you are concerned, last longer than three weeks, appear again and again, or get worse, hurt more, and become red, you should see your doctor.
