Noninvasive methods advocated by some clinicians are not very successful in dealing with patient gagging, while sedation approaches run the risk of the patient aspirating foreign bodies. The P-6 Neikuan acupuncture point, located on the wrist, has been used in the Far East for thousands of years for its anti-nausea and anti-anxiety properties. In the West, it is the acupuncture point most studied. Only recently has interest been shown in the P-6 point for its possible anti-gagging effect. The anti-gagging effect of P-6 stimulation is documented in this article. The P-6 point has remarkable anti-gagging effects if stimulation is applied correctly. Clinicians may apply thumb pressure at the P-6 point to achieve some effect, although this is not as effective as acupuncture. Nevertheless, a substantial percentage of gagging patients would be able to go through dental procedures without gagging when the P-6 point is stimulated.
