Permanent 3rd molars begin to calcify at what age?

  1. 5-7 yrs

  2. 8-10 yrs

  3. 10-12 yrs

  4. 12-14 yrs

The correct answer is: 8-10 yrs

The permanent 3rd molars, also known as wisdom teeth, typically begin to calcify and develop at the age of 8-10 years. This process continues into the teenage years and can vary between individuals. The other options of 5-7 years, 10-12 years, and 12-14 years are incorrect because they fall outside of the typical range for 3rd molar development. Additionally, it is important to note that this is a general guideline and the development of wisdom teeth can vary based on genetics, diet, and other factors.
