An interesting article titled “Dentist shocked by Mary’s new wisdom,” appears in an article in This is Kent, http://www.thisiskent.co.uk/Dentist-shocked-Mary-s-new-wisdom/story-17958765-detail/story.html, January 25, 2013.
The article describes a 75 year old woman who had a wisdom tooth grow in at the age of 75. A picture of the woman with her dentist is provided in the article.
The dentist was taken a back by such a finding since it is vary rare. He decided to look up other cases on the internet and did find a case where an 84 year old man in New Zealand where a man had a wisdom tooth come in.
In the case of the 75 year old man the dentist and woman have decided to just manage the wisdom tooth and leave it in in order to avoid possible complications.
