I have a toothache I had it for a couple days and yesterday night my mouth started feel numb can it be from the toothache?

Certainly. If that is the case, you need to see a dentist ASAP. The numbness can be caused by internal pressure from an infection pressing on tissues, resulting in the paresthesia. Failure to immediately treat can cause permanent damage. Please call now.
Emergency. You have an infection that is spreading to other organ systems. Imperative that you see a Dentist ASAP.
