Dental anatomy of dogs
The mouth of animals performs several important functions of life. This is not only a meal and water. She plays an important role in grooming, thermoregulation and communication. Dentistry is very important for the health and well-being of animals.
Dogs are carnivores and their teeth reflect their carnivorous evolutionary history. Domestic dogs, of course, are turned into omnivores, since most dry dog foods contain a significant amount of plant food.
A common anomaly in the formation of the canine jaw is the preservation of primary teeth. This occurs when the permanent teeth do not grow immediately behind the milk teeth, and therefore do not tear out the roots of the milk teeth and go out nearby.
The placement of teeth in dogs depends on the shape of the skull. There are three main forms of the skull in dogs:
Brachycephalic: short, broad muzzle. For example, Pekingese, pugs.
Mesocephalic: muzzle of medium length and width. For example, Golden Retriever, Terriers, most cats, and ferrets.
Dolichocephalic: long, narrow muzzle. For example, Dobermans, Greyhound, oriental cats.
Types of teeth
All mammalian predators have teeth located in the upper and lower jaws. There are four types of teeth with various functions:
Incisors: cut and bite food
Canines: Hold and Tear
Premolars: cutting, holding and cutting food
Molar (Molars): grinding food
How many teeth does a dog have?
Many mammals, including dogs, cats and ferrets, have two sets of teeth, one set (the so-called “baby teeth”) falls out and is replaced by a permanent set. Although the exact number may vary, puppies usually have 28 (14 bottom and 14 top) temporary, deciduous teeth, and adult dogs have 42 (22 lower and 20 upper) permanent teeth. At the same time, kittens have 26 dairy, and adult cats have 30 teeth.
Teething. When do dogs change teeth?
In puppies, milk teeth begin to erupt at 3-4 weeks of age and permanent teeth begin to appear at about 3-4 months of age. Up to 24 weeks of age, as a rule, all permanent teeth already grow.
Incisors 4-6 weeks 3-5 months
Fangs 5-6 weeks 4-6 months
Premolars 6 weeks 4-5 months
Molar 5-7 months
Milk teeth should fall out with the appearance of permanent teeth. If this does not happen, they must be removed surgically to prevent the loss of permanent teeth.
