Why does your jaw swell after you begin to chew your food?

Jaw swelling after chewing can occur due to several reasons, including muscle fatigue, inflammation, or an allergic reaction. When chewing, the jaw muscles exert force, which can lead to temporary swelling if they are overworked or strained. Additionally, conditions like temporomandibular joint (TMJ) disorders or dental issues can cause discomfort and swelling in the jaw area. If the swelling persists or is accompanied by pain, it’s advisable to consult a healthcare professional.
