The milk teeth
During birth when our dog no teeth present in
are, first break the milk teeth - around the age of 4 weeks -
in the lower jaw, sometimes a little earlier, by.
By the end of the 6th Week of life is then the complete primary dentition formed.
It is in the upper and lower jaw and right respectively from the left:
3 milk incisors (front teeth)
1 milk caninus (Fang)
3 milk premolar
The second last milk premolar of the maxilla and mandible in the last Milchprämolar work together and form the fangs.The milk teeth are slender and more pointed shape as the permanent teeth and often slightly bluish
stained. Each tooth consists of crown, root and Zahnhöhle.Das primary dentition has 28 teeth, premolars are missing here is the 1 (of 4) and molars (10), only once for the permanent teeth grow up.

the permanent dentition dogs
correct numbering of the permanent dentition
The left and right of the upper jaw:
|
The left and right in the mandible:
|
3 incisors (front teeth)
1 canine (fang)
4 premolars (Vorbackenzähne)
2 molars (back teeth)
|
3 incisors
1 canine
4 premolars
3 molars
|
Overall, are therefore in permanent, full dentition 42 teeth, 20 in the upper jaw and 22 in the lower jaw.
Most obvious and greatest from this are the fangs and the fangs
(In the upper jaw, these are: the fourth premolar in the mandible: first molar).
Bite positions:
Scissor bite
So it should PRT / JRT be with - the incisors of the maxilla with scissor-like over the incisors of the mandible, also should lower canine tooth between canine and extreme incisive maxillary access d., the premolars should alternately engage and the upper jaw than the lower jaw may be wider .
|
|
Bite
The incisors of the upper and lower jaws engage each other like pliers.
|
|
Overshot
In undershot means the extension of the mandible, the lower incisor teeth from the upper incisor arc stand that.
|
|
Re bite / overbite
Referring back to bite means the extension of the upper jaw, the upper incisors with distance from the lower dental arch are provided.

Tooth defect in the sense of missing teeth (premolars frequently, but also molars and incisors), malocclusion and dental deformities are not uncommon. And return bite (all DISQUALIFYING) How Faulty mouth pliers, it should be a strong genetic component, such as the mode of inheritance is missing teeth working for but still completely unknown. 2 full dentition parents can bring offspring missing teeth, missing teeth can parents with full dentition but also bring puppies. The genetic explanation is therefore still out ...
The goal should of course be accessible dentition dog breed, but if a dog until 1 or 2 missing molars and premolars otherwise error-free to, you can probably lucky;)
