Clean the wound. Using a syringe or other field expedient device, irrigate the wound with clean water in order to remove debris. Antiseptic can also be applied to lessen the likelihood of infection. Apply a pressure bandage directly over the wound (with guaze, and preferably a hemostatic agent, packed into the wound).
Daily irrigation. There are several types of oral irrigators, but like all self-care devices they require daily use for maximum efficacy. The most common type for home use is a pulsed flow irrigator. There are also direct flow or steady stream irrigators. Most of the studies completed on oral irrigation were done using pulsed irrigators by Waterpik Technologies. Results cannot be extrapolated to other pulsating devices or direct flow irrigators.
