i had impacted wisdom teeth and found that co-codamol and ibuprofen at the same time were really good.you can get cocodamol at the chemist without prescription.you can get higher dosage ones through your doctor to tide you over until you get to the dentist if you find they help but need a higher dosage. they make some people a little groggy but are worth a try if you can take them with any other medication you may be on or maybe just at night to try to get a bit of sleep.
i also used clove oil which you can get from a dentist, use it with a cotton bud to rub on the gum.tastes horrible but numbs it.oragel doe the same kind of thing.
tooth pain really is horrible, ive had similar problems since having the children.
good luck, i hope it gets sorted soon for you.
