Every toothpaste commercial from when the time commercials were invented to today show the top of a toothbrush that’s completely covered with toothpaste (complete with a tip that curls upwards at the end). Is that enough?
Actually – that’s MORE THAN enough. Dental professionals agree that toothpaste the size of a pea should be sufficient enough to clean a full set of teeth. Alternatively, you can apply a a very thin layer of paste on the length of the brush bristles. Anything more than that is wasted.
