Why shoulnt you let a doctor put one of those wooden sticks in your mouth?

You shouldn't let a doctor put a wooden stick, like a tongue depressor, in your mouth if you have a known allergy to the materials used or if the instrument appears unclean or damaged, as this could pose a risk of infection or allergic reaction. Additionally, if you feel uncomfortable or have concerns about the procedure, it's important to communicate these with your doctor, as they can provide alternatives or reassurance. Always prioritize your comfort and safety during medical examinations.
