A puppy’s teething is not hard to understand, but little is written about it. A puppy is equipped with two sets of teeth: the “temporary”, which appear during the first month (milk teeth) and the “permanent” which appear after 4 months. The temporary consists of 6 incisive, 2 canines and 6 premolars in each jaw, superior and inferior. The permanent consists of 6 incisive, 2 canines, 8 premolars and 4 molars in the superior jaw; and in the lower jaw six incisive, two canines, 8 premolars and 6 molars. Dental diseases inare pretty frequent. When there is at two of fracture, meanwhile the fleshy cavity isn’t damaged, it isn’t necessary to extract the tooth, but if the fleshiness is open, the pain is extreme and intense. Enamel hypoplasia (underdevelopment of an organ because of a decrease in the number of cells), can be due to a deficient calcification or infectious diseases, like distemper, deficient nutrition, or serious cases of parasites. These teeth can get cavities easily, and tend to look stained. There are, additionally, a whole lot of other afflictions that affect the teeth; direct or secondary. In almost all the cases there is halitosis and lack of appetite, presence of gingivitis and ulceration of the gums, pus in the gingival crevasse or loose teeth. If the dog continuously swallows the pus, it can affect his kidneys. Plaque must be removed periodically, as if the accumulation is big, the gums tend to move back, leaving the root exposed, and subsequently weakening the tooth. The dog suffers a lot of pain and stops eating, which can be serious. In any case, take him to the veterinarian.
