The coolmint is a delicate pleasant formulation that doesn’t sting or make your cheeks burn as you gargle. You need only 10mls in the uniquely designed cup for 1 minute twice a day. This product was so effective that the pain and ringing sensation that I would get on drinking hot and cold drinks actually disappeared. No longer would I “hold’ drinks in my mouth cautiously as the gums and teeth howled with pain. It’s changed the way I eat.
