Dog Age Estimation: Tooth Analysis for Accurate Age Ass

Understanding a dog's age is primarily determined by examining the growth of their canine teeth, including the condition of the tooth tips, the degree of wear, the shape, and the color. To help you gain a better understanding of your furry friend's dental health, Dr. Oxygen Pet will provide a detailed explanation.

1. Adult dogs have 42 teeth, while puppies have 28. Puppies start teething around 20 days old.

2. At four to six weeks of age: The deciduous incisors (baby teeth) emerge. Around two months, all puppy teeth should be in place, characterized by their white, slender, and pointed appearance.

3. Between two and four months: The first deciduous incisors begin to fall out.

4. At five to six months: The second deciduous incisors and the second deciduous canine teeth are replaced.

5. After eight months: All deciduous teeth are replaced by permanent teeth.

6. At one year: Permanent teeth are fully grown, with clean, bright white teeth, and the upper incisors are sharp.

7. At one and a half years: The large尖peak of the lower second incisor wears down to a small peak, a phenomenon known as尖peak wear.

8. At two and a half years: The second incisor on the lower jaw starts to wear.

9. At three and a half years: The尖peak of the upper first incisor wears down.

10. At four and a half years: The upper second incisor wears down.

11. At five years: The lower third incisor shows slight尖peak wear, and the first and second incisors have a rectangular wear pattern.

12. At six years: The lower third canine tooth has a sharp尖peak, and the canines are rounded.

13. At seven years: The lower first incisor wears down to the root, with a longitudinal elliptical wear surface.

14. At eight years: The lower first incisor wears forward, tilting towards the front.

15. At ten years: The upper first incisor and the lower second incisor have a longitudinal elliptical wear surface.

16. Between ten and sixteen years: Dogs may experience uneven tooth loss.
