Do garlic powder work on tooth aches if so what do i do?

That's a new one...: I've never heard of garlic powder helping with a toothache. If it does, i'd be somewhat surprised. I have heard of people using cloves or clove oil, though this is only a temporary sedative. Seeing a dentist is the only real thing to permanently get rid of a toothache.

Crushed garlic: Garliuc does have medicinal value. When crushed or finely chopped two chemicals in the garlic join to form allicin, which has antibiotic properties and can offer some relief. You must crush the garlic to form allicin. Be aware that crushed garlic can be irritating to the gum so restrict it to the cavity in the tooth.

No: Ibuprofen helps, visit your dentist.
