i have no idea how, but i somehow broke a tooth. i went to the dentist today to find out that the tooth is cracked and i need to have a root canal and a crown. thankfully i'm not in any pain. i'm more afraid of getting the novacaine because of the needles than i am the root canal itself. i'm one who doesn't get any novacaine when i had a cavity filled because i'm so afraid of the needle.
