I have 6 wisdom teeth, should i be worried about this?

You've been born with a few extra teeth. If your dentist feels their position poses no risk to you, then don't worry.

Worried, no. While missing or extra teeth are uncommon, they are not rare. Your Dentist has probably discovered this anomaly by examination and/or x-ray. He/she would be in the best position to advise you. Ask your Dentist as to whether an Oral Surgical consultation is in order. And you're never too old to renew your faith in the Tooth Fairy.
