2. This Distemper of the Teeth and Gums does also proceed from the various sorts of Meats and Drinks, and more especially from the continual eating of Flesh, and fat sweet things, compounded of various things of disagreeing Natures, which do not only obstruct the Stomach, but fur and foul the Mouth, part thereof remaining upon the Gums, and between the Teeth. For all such things do quickly turn to Putrifaction, which does by degrees corrupt both the Teeth and Gums. Besides, our Beds take up near half the time of our Lives, which time the Body is not only without motion, but the Bed and Coverings do keep it much hotter than the Day-garments, especially of those that draw the Curtains of their Windows and Beds so close, that the pure Spirits and thin refreshing Vapours of the Air are hindred of having their free egress and regress, which does dull and flatten the Action of the Stomach; and this is the chief Cause why Suppers lie hard in the Stomach, and require more than double the time for perfect Concoction, than the same Food does when a Man is up, and in the open Air: For this Element, if it hath its free Influences, is sucked in, as by Spunges, through all the Pores of the Body, and does wonderfully refresh, comfort, open, and cleanse all the Parts, having power to assist and help Concoction: but hot, dull, thick Airs do destroy the Action of the Stomach, and as it were suffocate the pure Spirits, drying up and consuming the Radical Moisture. Therefore the Night does foul the Mouth more than the Day, furring it with a gross slimy Matter, especially those that have foul Stomachs, and are in Years, which ought to be well cleansed every Morning. 3. Whatsoever are the Disorders in the Body, the Mouth does always partake of them; besides the Evils that the variety of Food, and the improper mixtures of Flesh and Fish, and many other things, which do foul and hurt both the Teeth and Gums. When any Person is disordered with inward Diseases, does not the Mouth quickly complain of the Evils thereof? This very few do consider in time.
