Same here, the joy of a good Marseille soap (I'm in France). It lasts at least 3 months for showers, washing hands, and everything (hair as well)
I heard some people wash their teeth with soap, I'm not there yet :))

For the sake of science, I just repeated that, so as taught in school, the scientific method.
experiment: brushing teeth with soap instead of toothpaste.
apparatus: toothbrush, soap (sainsbury's cheapo), teeth, darwin-award level of stupidity.
result: surprisingly inoffensive. Almost no taste of soap unless the suds reached the very back of your tongue. Considerably foamier than toothpaste!
conclusion: for this brand of soap at least, an acceptable substitute. Minty soap would be better.
Note that toothpaste actually contains a very fine abrasive which soap lacks. Also laundry soap (came in thick green bars IIRC) was probably far worse.
Most of the cleaning comes from the action of the brush on your teeth which physically removes bacterias, leftover food, &c.
