![This deposit appears to be of two kinds— the first and most pernicious, although less in quantity, is the greenish, thin substance, which attaches itself to the exterior surfaces of front teeth. It eats granularily into the enamel, and when permitted long to remain, arrives at the bony substance, which gra- dually becomes dark and soft, so that adhesion of the shattered enamel soon ceases, until at length the upper half of the body of the tooth is totally decayed, while the remaining half, towards the cutting edge, is perfectly sound. To this species of attack the.shedding teeth, from the neglect so natural to children, are peculiarly liable, as well as the permanent ones.* This tartar, increasing with time, in- sinuates itself between the gums and teeth, occasioning their complete separation, until it is deposited on the teeth, as the saliva undergoes decomposition. The formation of tartar is much influenced by the state of the health, Fox. * There is another kind of tartar, which collects chiefly about the teeth of young persons; it corrodes the enamel], and disposes the teeth to be carious.
