Q.  How much toothpaste per brushing is recommended?

A.  According to dental research, one gram of fluoride toothpaste per brushing is the desirable quantity.  That equals approximately one-half an inch of toothpaste, depending on the size of the tube opening.  As for pumps, one spurt is plenty since this amount weighs 1.6 grams.  It is important to use at least one gram of toothpaste per brushing because if you use too little, saliva will dilute the fluoride concentration, resulting in less effective decay prevention.
