How do you tell the age of a teddy?
Let’s start by looking at the condition of your Teddy’s teeth between ages.
Distribution of permanent teeth in an adult teddy: 6 incisors top and bottom, 2 canines top and bottom, 8 premolars top and bottom, 4 molars in the upper jaw and 6 in the lower jaw, for a total of 42 teeth.
Distribution of the number of milk teeth in a young teddy: 6 upper and lower incisors, 2 upper and lower canines, and 6 upper and lower premolars, for a total of 28 teeth.
The age of an adult teddy is most obvious in the growth, wear and sharpness of the teeth, so we can determine the age of our puppy by the number, strength, newness and brightness of the teeth.
Criteria for judgment:
Teeth gradually come out in a jagged pattern around 20 days.
30-40 days, the milk incisors grow in.
At 2 months, the milk teeth are all grown in, with a fine and tender white tip.
At 2-4 months, replace the first milk incisor.
At 5-6 months, replace the second and third milk incisors and all milk canines.
At 8 months or more, all teeth are replaced with permanent teeth.
At 1 year of age, the permanent teeth are long, polished, and strong, with cusps on the upper incisors.
At 1.5 years of age, the cusp of the first mandibular incisor was worn down.
At 2.5 years of age, the cusp of the mandibular second incisor was worn down.
At 3.5 years of age, the cusp of the first maxillary incisor was worn down.
At 4.5 years of age, the cusp of the maxillary second incisor was worn down.
At the age of 5 years, the cusp of the mandibular third incisor was slightly worn while the mandibular first and second incisors were worn in a rectangular shape.
At 6 years of age, the cusps of the mandibular third incisors were worn down and the canines were bluntly rounded.
At 7 years of age, the mandibular first incisors were worn down to the roots of the teeth, with a longitudinal oval wear surface.
At 8 years of age, the first incisor of the mandible is worn down and tilted forward.
At the age of 10 years, the wear surfaces of the mandibular second and maxillary first incisors were longitudinally oval.
16 years old, lost incisors and incomplete canines.
20 years old, canine teeth falling out
Teddy’s general life expectancy of 12 to 15 years, can be more than 15 years of very few very few, this and its living environment, eat food, and other aspects of the impact of the reasons are inseparable. Through the Teddy’s teeth to determine the age of the dog or more accurate, friends can try Oh.
