True, I had a toothache about a half a year ago and all they did was give me some antibiotics. I'd go into detail as to why I needed antibiotics to treat a toothache, but its not really important, and kind of icky.
Anyway, I wasn't really refering to treating a tooth without drilling, but to treating a headache with drilling. Sometimes you have to drill a hole into the skull to release the presure inside it. For example then the brain is bleeding. The blood can't flow anywhere and so it just stays at one spot, building up pressure inside the skull. Very serious condition..
The problem is, they SAY Twilight's the smart one, but she never actually demonstrates any intelligence. Sure she knows a lot of things, but knowing things and applying them to appropriate situations are two different things.
Hell the entire reason she even HAS a spell for everything is because she can't think to use a spell for anything other than it's textbook use.
