I put the pen in my mouth while focusing on school work, accidentally the tip was the thing that went in my mouth. It touched my tooth a little, and the side of my lip and cheek inside. Is this okay? Not sure, because i was always told "pens are poisonous" although, others tell me it's not. I'm not sure if i'll die, so please answer!

If you cannot answer this, it's okay i'll do more research, but i'm looking for a real doctor or someone i can trust to answer this, "i think you won't die" type of people are okay answering, as it'll give me confidence, but still i'd recommend a professional. Thank you!
