I am a widow raising a grandson. About ten years ago, I went to the dentist and he said, How do you stand the pain? I said, Thre is no pain because I brush my teeth with tea tree oil. I have diabetes and the way I understand, diabetes and gingivitis go hand in hand. Tea Tree Oil doesn't cure the gingivitis but it really helps keep infection down. I use Tea Tree Oil for many of the different remedies listed. Once I used it on a diabetic man's feet, which were in really bad shape, and it helped him immensely. Personally, I'd hate to live in a world without Tea Tree Oil!
