Can Mouth Ulcers Cause Fever?

Mouth ulcers, also known as canker sores, are typically small, painful sores that form inside the mouth, on the gums, tongue, or the inside of the cheeks. While mouth ulcers themselves are not likely to cause a fever, they can sometimes be associated with other symptoms that may lead to a mild increase in body temperature.

Mouth ulcers can be caused by various factors, including:

  • Minor injuries: Biting your cheek or tongue, using a toothbrush with stiff bristles, or accidentally injuring the soft tissues of your mouth can trigger the development of mouth ulcers.
  • Stress or trauma: Emotional stress or trauma to the mouth can sometimes lead to the formation of mouth ulcers.
  • Dietary factors: Certain foods, such as acidic or spicy foods, can exacerbate or trigger mouth ulcers in some individuals.
  • Underlying medical conditions: In some cases, mouth ulcers may be associated with underlying health conditions, such as vitamin deficiencies, autoimmune diseases, or gastrointestinal disorders.

If mouth ulcers are causing significant pain, discomfort, or other symptoms that disrupt your daily life, it’s important to consult a healthcare professional or dentist for a proper evaluation. While mouth ulcers themselves do not typically lead to a fever, an underlying condition that may be contributing to the ulcers could potentially cause fever as a symptom. Therefore, it’s essential to identify and address any underlying issues if you are experiencing persistent mouth ulcers along with other concerning symptoms.
