i learned that ingesting charcoal can affect birth control pill effectiveness. using a charcoal activated toothbrush (w/regular toothpaste) — does that have a similar effect?

Activated charcoal: Likely to not have effect with activated charcoal toothbrush as you do not swallow charcoal on toothbrush while brushing teeth.
