We humans have a lot of fears, and many are for a good reason. Snakes because poison. Heights because falling. Dentist because… wait, why do we fear the dentist again? It’s an extremely common fear: in fact, seven out of 10 adults report having some fear of the dentist. Unfortunately, as many as half of adults avoid visiting the dentist as a result of their fear, only seeking treatment when their tooth pain becomes unbearable — and that’s a real problem.
