There are certain microbes found in calcareous teeth; but whether they are directly connected with the decay of the teeth is not defi- nitely known. True dental caries is very rare in the dog. Necro- sis of the teeth is frequently mistaken for caries. In old dogs we often see an acute inflammation of the periosteum, and the alve- olar process becoming inflamed the tooth is lifted out of its socket and finally thrown out. In these cases the alveolar periosteum is destroyed, and the necrotic condition of the tooth causes it to be- come yellow; this is generally termed false caries of the teeth. Alveolar periostitis commences with the formation of an abscess at the root of the tooth, and the pus formed finds its way to the outside through the alveolar process and the gums. It forms a fluctuating swelling on the gums (abscess of the gums) ; the open- ing generally remains so, and if it is in the superior maxillary open fistulous tracts may form under the eye, jnst below the lower eye- lid, and unless carefully examined may be mistaken for a lachry- mal fistula. By means of a flexible probe the diagnosis can be made with safety. In all these cases the animals seem to have a more or less severe toothache; they are irritable, eat very slowly and irregu- larly, drop more or less saliva, refuse to have the mouth examined, and, if the af- fected tooth is struck with anything (a key is the best), howl and evince great pain, keeping the mouth open for some time after- ward. When there is more or less pus present the radical treatment is to remove the offending tooth. For this purpose open the mouth by the method described on page 27, or a wedge, and with an ordinary molar- forceps (Fig. 15) extract the tooth, being careful to avoid breaking the crown. The tooth is firmly seized with the forceps as fa
