Is needing a crown at 27 years old uncommon?

I cracked my left second molar on my upper jaw while eating. It cracked to the gum line. My dentist said that the best option is to place a crown not a filling. I'm a 27 year old male and have never needed any dental work done, I've not had any major cavities so I'm feeling a bit self conscious that I need a crown on my tooth at this young of an age and I'm hoping this doesn't mean my teeth are on their way out. Is it rare for people my age to have any crowns in their mouth?
