Dog deciduous teeth

2(Di3/3, Dc1/1, Dp3/3)=28. Is this Morse code?
To explain, it means dividing all the dog’s teeth into four areas: upper left, lower left, upper right, and lower right. In one area, there are 3 incisors, 1 canine, and 3 premolars. There are a total of 28 teeth in the 4 areas.

Dog permanent teeth

2(I3/3,C1/1, P4/4, M2/3)=42.
In one area, there are 3 incisors, 1 canine, 4 Premolars. There are 2 molars on the top and 3 molars on the bottom. There are 42 teeth in total.
How do teeth tell your age? For puppies, it mainly depends on when the deciduous teeth come in and when the teeth are replaced. How to distinguish deciduous teeth from permanent teeth? Deciduous teeth are thinner and pointed, while permanent teeth are stronger. For example, in the picture below, the one on the left is the canine tooth of the deciduous tooth, and the one on the right is the canine tooth of the growing permanent tooth.

Time of appearance of deciduous teeth

Incisors: Dogs are 3-5 weeks old
Canine teeth: Dogs are 3 weeks old -6 weeks old
Premolars: Dogs 4-10 weeks old

After the deciduous teeth fall out, the time for permanent teeth to appear

Incisors: Dogs are 3-5 months old
Canine teeth: Dogs are 3.5-6 months old
Premolars : Dog 3.5-6 months old
Molar teeth: Dog 3.5-7 months old
It’s hard to remember, so it’s simpler. If some of the teeth have been replaced, some If it is still baby teeth, the best estimate is 4-5 months. The time when the last baby tooth has just been replaced is about 6 or 7 months.
In adulthood, teeth can also be used to estimate age. If the teeth are often white and shiny, it is usually about one year old. Dogs will usually start to have tartar when they are two or three years old. Note that tartar will start to accumulate on the molars first. If there is a lot of tartar or the teeth are worn, they are old. But this also has a lot to do with the dog’s usual habit of cleaning his teeth.
