Input (English): [header] How to tell between an erupting and impacted wisdom tooth [title] Know where to look in your mouth. [step] Your wisdom teeth are the last molars on each row of teeth-the uppers and lowers on both sides. They are meant for grinding food. <sep> (A) They are also for self-control in emotions, misunderstandings, and improvisation. [substeps] Look for the wisdom side of your mouth. (B) These teeth are tiny enough to be used for grinding an entire piece of food. However, they can cause severe jaw pain if swallowed, so it's best to check with your dentist if you're unsure about where to look. (C) The uppers sit on the roof of your mouth, so that the front teeth have a space to release food and saliva. [substeps] When you notice the top of your mouth growing upward, this can send a message. (D) You don't need them to chew properly, but they pop up (erupt) when your jaw grows and elongates during your late teen years. Open your mouth wide and use a penlight to see the back of your mouth.
