The pain from a toothache usually lasts between 1 to 2 days depending on how severe the toothache is and what is causing the tooth to ache.
You can help get rid of a toothache by sucking on a warm teabag or even sucking on some ice.
Taking some aspirin or Ibuprofen can also help relieve a toothache.
I would also recommend gargling with some apple cider vinegar as the apple cider vinegar can help kill off the germs and bacteria that could be causing your toothache.
You can also buy some toothache medicine which will help much better or even use some Orajel on the toothache.
Hydrogen peroxide is also another way of treating a toothache and it kills germs and bacteria as well.
