Sakina Di Pace | Facial Cupping Expert on Instagram: "Teeth grinding isn’t just something adults do little ones can hold a lot of tension in their jaws too. Using the gentle care cup over the masseter muscle is a simple way to help release that tightness. It’s lovely to do in the evening, just before bed, to calm and relax the jaw. Sometimes my son even drifts off to sleep while I’m doing it. Always keep the suction light and the moves gentle, and use a soft oil like prickly pear or almond. Comm
