Tooth-Mag is here!.

Great for daily hygiene and  healthy gums while providing magnesium which helps fix calcium to the bones. Spray once on your toothbrush—brush and spit as usual. If you have deep pains, improperly extracted wisdom or other teeth, root canals, sugar pain etc. use 10-20 sprays in the mouth and let sit for 20 minutes then spit. This life changing product does not taste great but it is powerful at even 1 spray per day. It is also great for oil pulling or as a mouth rinse.

Magnesium has many properties when it comes to relief  for tooth pain, root canals, sugar pain, cold sores etc.
