Which toothpaste should I use?
The brand of toothpaste you use is less important than the amount you use. Toothpaste contains abrasive material like sandpaper. If you use too much toothpaste over the years, you will wear away the teeth. Many of you have notches in the teeth near the gum line. These notches were caused by the sandpaper-like effect of toothpaste.
Always use a low abrasion toothpaste that does not irritate the gums. Also, sodium lauryl sulfate, which makes toothpaste sudsy, and sodium pyrophosphate, contained in some anti-tartar toothpastes, sometimes irritate the gums. If you are sensitive to these chemicals, avoid toothpastes containing them. Consumer Reports lists many good options.
