is it possible for me to use a piece of lidocaine patch to numb a toothache?

No: Lidoderm patches should only be used on intact skin. Aspirin is an excellent analgesic for tooth pain but often dental pain is secondary to an abscess which requires antibiotic treatment prior to dental procedures. Contact your dentist

Doubtful: I doubt that a patch can give sufficient anesthesia to a tooth root from the skin.

Won't work: you'll need to see a dentist to evaluate and treat that tooth.

Dental Treatment: is the only option for your dental care. Take NSAIDs or Tylenol (acetaminophen) OTC and see your dentist ASAP for evaluation, x-rays and treatment.
