Ok, so if I've read one opinion on gargling with sea salt, I've read 20. Bottomline, is it ok to gargle 2-3 times a day with a sea salt water mix? I find it works remarkably well for keeping my gums healthy. For years, I've used Listerine, but find the sea salt so much more refreshing than alcohol based Listerine and, truly, my gums seems healthier for it. From your professional standpoint, are there any cautions one should exercise with a sea salt gargle? I do NOT brush with salt, however, as I've read that it can be abrasive/damaging to enamel...is that accurate? Thank you.
