I can give you a personal experience: I had to have a tooth pulled out two years ago and had to have my jaw bone cut up in the process to help me get a dental implant. The doctor gave me a prescription for pain meds, but all I had to do was needle three points and I had no pain. I went back for more work and the doctor was pushing on my jaw the whole time he worked, so the next day I had a couple of my acupuncture students work on some other points to relieve the pain my neck endured from his jaw pushing work. I never used the prescription in either time. Once the body is flowing properly again, there is no pain.
In order to fully answer your question, I would need to know your full case. If you choose to go get acupuncture, you'll need to be assessed by the practitioner on which is the best route to take for you.
Very interesting! I have used acupuncture to deal with a patient’s gag reflex. Alternative medicine is interesting, but not a panacea to deal with all dental pain. Perhaps if the pin is muscular, it may help, but if tooth-related, you will need to see a dentist.
Hope this helps.
Please consult your physician first for any referral and recommendation. Having said that, TCM is known to treat pain. According to TCM, pain could be due to "qi" stagnation, blood stagnation, due to heat (inflammation), and cold. TCM also has herbal medicine that can help with pain as well. Have your doctor refer you to your nearest acupuncture clinic and give it a try.
Acupuncture can definitely help manage any pain/discomfort in the meantime.
If you have dental anxiety, acupuncture can also help. If this is the case, I'd suggest scheduling an acupuncture appointment either the same day (ideal) or 24 hours prior to your dental appointment.
Explaining how it works is a little more complicated. From the perspective of biochemistry, acupuncture appears to be affecting a set of neurotransmitters which have a lot to do with the transmission of pain signals in the brain and spinal cord. There is also evidence that acupuncture is changing the way the pre-frontal cortex in the brain processes pain signals coming from the body.
Generally, for tooth/mouth pain, I'll use points on the hands and feet.
