I was supposed to talk about something different today, but my mom got toothache lately so I tried to find if there's any reflexive area on the hand that can help sooth her pain. It turns out I found a few acupoints and a reflexive area on this hand acupressure therapy book. So again, I'm going to translate and share here.
Acupressure on hand can only reduce the pain of toothache, it doesn't cure the teeth problem. Toothache can be caused by infection or tooth decay. After all, dentist is needed for the real cure.
Stimulate the following acupoints and reflexive area in the diagrams, just remember you have to use a pointy device to stimulate the acupoints until PAINFUL in order to be effective.
1. For pulpitis (or neuralgia), use a pointy device to stimulate the "Kidney Acupoint" at the middle of the first line of little finger, palm side --- this may sound like a little weird, but according to TCM, Kidney "channel" is related to toothache.
2. For apical inflammatory, stimulate the acupoint called "He Gu" at back of the hand almost the conjunction of thumb bone and index finger bone (see diagram). Or massage hard on the reflexive area for Oral and Bronchitis (see diagram).
3. For periodontitis, stimulate "He Gu" and also the "toothache point" between the root of middle finger and ringer finger within 1cm below.
The Oral and Bronchitis reflexive area is a very helpful massage area for temporary relief of toothache. The key is to massage that area HARD with your other thumb and index finger. Also, stimulate the "Liver Acupoint" as the diagram shown helps tooth pain caused by coldness. For "He Gu", if you stick a little bean at that acupoint for few minutes, that would help too.
