Can Wearing A Face Mask Cause Mouth Ulcers?

It is generally accepted that wearing a face mask, specifically a cloth mask or surgical mask, is not a direct cause of mouth ulcers. Mouth ulcers, also known as canker sores, are a common oral health issue that can be caused by a variety of factors, including stress, hormonal changes, certain medications, and vitamin or mineral deficiencies.

There is some evidence that the use of face masks may contribute to the development of mouth ulcers indirectly, through mechanisms such as increased moisture, friction, and irritation. For example, wearing a mask may cause the mouth and lips to become dry and chapped due to decreased airflow and increased humidity. This can lead to the development of mouth ulcers in people who are prone to them.

However, the majority of research on the topic has found that the use of face masks is not a significant contributing factor to the development of mouth ulcers. A systematic review published in the Journal of the American Dental Association in 2020 examined the existing evidence on the relationship between face mask use and mouth ulcers and found that there was a lack of strong evidence to support a causal relationship between the two.

It is important to note that the use of face masks is an important public health measure to help prevent the spread of respiratory infections, including COVID-19. While the risk of developing mouth ulcers as a result of mask use may be low, the benefits of mask-wearing in preventing the spread of disease far outweigh any potential risks.

If an individual experiences mouth ulcers while wearing a face mask, it is important to consider other potential causes and to speak with a healthcare professional for guidance on managing the ulcers and addressing any underlying causes.

In conclusion, while it is possible that the use of face masks may contribute to the development of mouth ulcers indirectly through mechanisms such as increased moisture, friction, and irritation, the majority of evidence suggests that face masks are not a direct cause of mouth ulcers. The benefits of mask-wearing in preventing the spread of respiratory infections far outweigh any potential risks. If an individual experiences mouth ulcers while wearing a mask, it is important to consider other potential causes and to speak with a healthcare professional for guidance on managing the ulcers and addressing any underlying causes.
