I came across this article in a Luxembourg newspaper which really seems odd. Is it possible to "grow" a wisdom tooth at 92? The article did not elaborate further, only talking about getting into the Guinness World Records. Checking up the Guinness website yielded the following:
"The oldest person to grow a wisdom tooth is Ingeborg Wolf-Wimmer (Austria, b. 10 June 1922) who was aged 92 years 258 days when a wisdom tooth was confirmed to have erupted, in Saarburg, Germany, on 23 February 2015. Ingeborg, who is originally from Austria, now lives in Luxembourg."
As it turned out, it is not so much "growing" a wisdom tooth but rather, a case of late eruption of the tooth. Wisdom teeth typically erupts into the mouth between late teens and early twenties, hence the term "wisdom" because this is the supposed age when one becomes a young adult and presumably, "wise", which is debatable but that's another story. So, for this lady, why did the wisdom tooth take so long to surface?
