As an aside to this it is my understanding on my reading that you should avoid brushing your teeth right away after smoking a cigar. If you must do so then it is best to rinse thoroughly before brushing your teeth.
The basis was (if I remember the article correctly) is that brushing your teeth breaks open blood vessels in your gums and you then allow the carcinogens from the recent cigar smoking. Apparently increasing your chances of mouth cancer.
I personally have stopped brushing my teeth altogether
