                    are independent of one another, yet enjoy a relationship of
                    perfect harmony. They are designed to press against one an-
                    other when the mouth is closed. For example, if one molar
                    were longer than the other teeth or if it protruded too much,
                    you could not close your mouth or speak and eat as you do
                    now.



                            Food is both ground by the teeth and attacked by
                    chemicals found in one’s saliva. No one really pays attention
                    to their saliva, whether it is being secreted or not, or in what
                    amount. But saliva, usually considered a simple secretion, is
                    actually a special balance of various chemicals. First of all, it
                    allows us to taste our food by recognizing the food molecules
                                    that give food its taste. Only when these

                                       combine with the tongue’s taste-sensing
                                        nerve endings can we taste food. This is
                                         also why we cannot taste food when
                                         our mouth is dry. The mouth secretes
                                        two kinds of saliva. One of them de-
                                         composes carbohydrates and changes
                                         them partly into sugar. For example,
                                         bread is a carbohydrate. If you put a
                                         piece of bread in your mouth and wait

                                         for a moment without chewing, you
                                         will sense the taste of sugar on your
                                           tongue from the decomposing carbo-
                                               hydrates. The other kind of sali-
                                                 va has a dense sticky consisten-
