Adopted a rescue animal with an unknown birth date? This calculator estimates approximate age using common dental wear indicators.

Estimated dental age: 3-5 years
Why This Method Is Useful for Rescues
Veterinarians commonly use dental wear, tartar buildup, and gum condition as one indicator of an animal's approximate age, particularly useful for rescue or stray animals with unknown birth dates where no other age indicator is available.
Why This Is Only a Rough Estimate
This is only a rough estimate, since dental health varies significantly by diet, breed, dental care history, and individual factors independent of true chronological age - a well-cared-for older animal can show less dental wear than a younger animal with poor dental hygiene.
