We have always been told to stay away from Baby Orajel in general, and if you've ever used it you'd want to anyway... the stuff is awful!
Switch to teething tablets, we use Hyland's, I have tried them and they are wonderful... they take the pain away (I have a tooth broken down to the gum and being pregnant the gum sensitivity has really aggravated it) but they don't leave that nasty cakey, horribly numb feeling like orajel does. And they're homeopathic.
