text: I'm sorry you're in pain sweetie. You could take some paracetamol as well to try to help ease the pain, and you could try rinsing your mouth with a hot salt water rinse, that sometimes helps me when I get toothache. Avoid anything that makes it worse, so don't eat anything sweet, and make sure you keep the cavity clean - rinse it out after every time you eat. If it gets worse, you should probably call the dentist to see if he can fit you in any sooner. Hope you feel better soon, there's nothing worse than a toothache!
