"Temporal" (pronounced: Nie) refers to the position on both sides of the head close to the ears. The "temporal muscle" is located near the temples and can be touched when opening and closing the chin. If this muscle is tense and overused, it will be easily injured over time and cause pain in a series of areas such as cheeks, head and neck, forehead and shoulders. The patient's teeth will also be worn shorter and shorter, making them feel sore and soft when eating, which will increase the chance of being decayed. Answer the following questions to test your condition.
