Yeah, most of the above. Lordofthepipering's suggestion on flossing is a good one. Stuff between your teeth can catch
and hold tobacco odors, I would think. All of the above being said, no non-smoker with a good sniffer is not going to
pick up the scent of tobacco. To some people, this might be better than stale breath, given generally good hygiene.
If the scent and taste of tobacco just turns your girlfriend off, you might have to choose between this girlfriend and
pipe smoking. Of course, everyone on the Forums is bias toward the pipe, but only you know this woman. Other
thoughts: Since you might brush more, be sure you are using a soft brush or you really will wear down the enamel
and make your gums recede faster. If you and your girlfriend drink, a small glass of brandy or sherry for you both
might equalize things flavorwise. If you don't drink, mint tea or something like that might work.
