Mouth soreness

Causes of Mouth Soreness

Mouth sores can be caused for a variety of reasons, and they can either be short-term or long-term. Here are some of the most common causes of mouth sores:

  • Infections – bacterial or viral infections are the source of some mouth sores, such as cold sores and canker sores.
  • Allergies – food allergies or contact with certain substances, like makeup or toothpaste, can cause irritation in the mouth and lead to sores.
  • Trauma – physical trauma to the mouth, such as biting your tongue or having braces adjusted, can cause sores.
  • Medicines – certain medications can cause sores in the mouth.
  • Hormones – hormonal changes, particularly in adolescent and pregnant women, can cause sores in the mouth.
  • Cancer – certain types of cancer, such as oral and throat cancers, can cause sores in the mouth.

If you experience any sudden or recurring mouth soreness, it's important to consult a doctor. It could be a sign of a more serious medical condition.
