Dent on skull since birth due to forceps. Pls help!!?

Ive had this dent on my head since my birth,its on my left parietal bone. Its due to the forceps used when I was born. Im 21 yrs old now. I want to know if a dent on the outside wud poke the brain on the inside? Its maybe a inch n hf in length and maybe arnd hf a cm in depth, where the top of the skull and the left side coincide. Ive had no problems developing. But Im noticing problems while speaking now, I have difficulty speaking at time. I can pronounce it well at times and at times I mess up real bad. Do I have social anxiety? Also I havent been the best at math. Still not as bad as many others in class. I read online tht the parietal lobe of the brain controls math reasoning and speech so Im freaking out! and this is probably whats causing my speech problems in the 1st place. I went to a doc, he said its nothing to wrry abt. But got a ct scan done and everythings normal. Am I normal? Can the dent on the inside damage the brain without showing up on a scan? Pls reply, I'll be grateful to u :) Im really worried
