How do I use a tooth powder instead of regular toothpaste?

A tooth powder is used in place of paste for a given brushing session, and the technique is simple once you have done it a couple of times.

1. Rinse your toothbrush and shake off the excess water so the bristles are damp, not dripping.
2. Pick up a small amount of powder. To keep the jar hygienic for the whole family, it is better to shake a pinch onto a clean dish or into your palm and dip the brush into that, rather than dipping a wet brush straight into the container.
3. Brush as you normally would, using light pressure and small circular motions. The powder itself does the polishing work, so pressing hard adds nothing except unnecessary wear on the enamel and gums.
4. Rinse your mouth thoroughly with water. Charcoal powder is black, so rinse until the water runs clear; a quick rinse of the sink afterwards keeps it free of dark residue too.

Two practical points specific to the powder format: keep water out of the jar, because moisture makes the powder clump and shortens its usable life, and close the lid tightly after each use. Store it in a dry place — a bathroom shelf away from direct splashes is fine.
