    hope others will add to this thread as it goes should be good fun and educational.

    ok theres 28 'normal' adult teeth in a dentition and 4 wisdom teeth that may or may not erupt.

    most of the function of the dentition is done by the 8 large molars which are actually 2 teeth fused together. (4 molars in each arch) pull these out and there are massive problems- heavy wear on front teeth, overloading remaining teeth, teeth moving about leading to bad breath and gum disease/ decay, jaw pains possibly, difficulty eating.

    most of the form or beauty is done by the front 10 teeth on the top. these are the only teeth most patients are interested in. funnily enough many dentists dont much look at these as their interest is in the function very reasonably which is much more important!

    Nothing to do with what you are talking about..
    But are there really teeth stuck together in everyone's mouth?
    Which ones? the ones behind the canine ones???

    Just interested like!

    hi lilrayofsunshine, the molars are indeed 1 tooth but for all intents and purposes are basically 2 premolars stuck together, if you take out 1 molar, you actually lose 4 teeth, as you then lose the use of the opposing one which is also '2 teeth'
    interestingly the lower molars have 2 roots as the bone is like concrete in the lower jaw but the upper molars have 3 roots as the bone is soft in the upper(designed to act as a crumple zone for brain).
    ironically the 3 rooted upper molars are the achilles heel of people who have gum disease as when the bone shrinks back a little past the root forks bacteria collectbetween the roots and then bone loss procedes rapidly and the tooth are basically hopeless.
