Oil of oregano used when you brush your teeth will tighten your gums up pretty quickly. The oil is pretty hot and tingles pretty good but it does a good job on the gums. I smear some toothpaste on my brush...NON-fluoridated...and drop a couple of drops of the oregano oil on top. It is beneficial to hold the foam in your mouth for a minute before rinsing too.
Make sure you get a quality oil of oregano.
Using a straw and rinsing your mouth or brushing after the lemonade is recommended as well.
