My daughter has a big fear on anything related to doctors. A dentist is a doctor so she'd be very squeemish to go to one. She'd rather feign a toothache than go to a dentist.
She's already in that age where she's shedding her baby tooth and is being replaced with the permanent ones so sometimes in the middle of the night, she'd ask for a cold pack or ice cubes to relieve the pain.
I bought her this small bottle of Bell's Toothache Tincture to give a temporary relieve until the dentist sees her wobbly tooth. Somehow, she get's a relief mometarily, just enough to get her through the night. It has a bit of a sting (as what my daughter said as she's the one who used this...) and the affected area slightly gets numbed. The taste is rather hot but if it will give a relief then it's good enough until the next day dentist appointment.
