What is cheeks hurt from smiling?

Cheeks can hurt from smiling due to the strain and tension put on the muscles in the face. Smiling for an extended period of time can cause the muscles in the cheeks to become fatigued, leading to soreness and discomfort. This is especially common in instances where someone is smiling for an extended period of time, such as taking a lot of pictures or attending a social event. Additionally, people who have recently had dental work or oral surgery may also experience cheek pain after smiling due to the pressure put on the affected area. In most cases, taking a break from smiling and allowing the muscles to rest can alleviate the discomfort.
