You may well be right. Also, I've always linked problems with teeth, gums, jaw, with unspoken anger stored in the mouth. I can't tell you how many people find they need a root canal after a period of intense stress and anger with colleagues or over a divorce. So I think there are internal/emotional matters to be considered as well.
I once attended a Buddhist retreat for ten days in England and within three days of arriving, my gums started bleeding profusely for no apparent reason. I would wake up in a morning and find a large patch of red on my white pillow, or be talking and suddenly blood would spurt out of my mouth. This was the stored-up emotion that, in a space of intense relaxation, rest, and calm, felt able to be released after years of anxiety and containment. Fascinating actually. So I now link dental/mouth issues to more than just hygiene. If we have problems in that area, we should look deeper and ask more probing questions about how we feel about the world, whom we're angry at, what measure of forgivenness and love we perhaps need to mete out to those who have hurt us, and so. It's quite a task, but good health is only 50% supplements and regimens and attitudes and exercise anyway. The rest, I'm finding, is all about positive attitude, life-affirming beliefs, constantly enhancing one's capacity to love and forgive, and a calm, constructive, faith-based approach to problematic situations.
