A small chip has appeared on one of my teeth near the gum line; should I go to a dentist?

I am very particular and careful with my teeth. But today I noticed a small chip on my tooth near the gum line and I was wondering if this was anything to be worried about. The chip is not really noticeable and I only realized it was there when a flake of pepper got in it. In middle school I chipped one of my molars and it seemed to grow back without any help from a dentist. Is the small chip something I need to get checked out or should I wait and see what happens?
