Which is worse, toothache or labour pains?

It depends: Everyone's pain threshold is different. Personally, labor pains are far worse. But it is subjective. But at least with labor, you usually get a beautiful baby after all that suffering. Can't say the same for toothache pain.

Good question: Only someone who experiences both could say. I do have many women that have told me they prefer the labor over the dentist. It would depend on your tolerance of pain and how you handle the anxiety associated. Toothaches can be very debilitating though if they are left too long.

Toothache: Nothing is worse than an abscessed tooth.

Kidney stone: Whichever you are currently experiencing seems to be the worst, but I believe that a kidney stone is the worst.
