Many kids aren't growing wisdom teeth.  And the reason is fascinating. 

The fact that kids aren't growing wisdom teeth is somewhat of a good thing especially since they usually have to come out any way.  Then there's the cost, not to mention the pain.

So what's changing the young bodies of today?  Research found that in some cases, kids who got anesthetic injections for dental work never grow lower wisdom teeth as they age.  Simple right?

The research found that children who had gone to the dentist for a procedure(s) in there younger years and who were given shots inside the mouth to numb the problem area, never grew wisdom teeth as they aged.

This is an amazing finding.  Imagine not ever having the hassle of wisdom teeth removal and all it take is a shot of a numbing anesthetic.  May just be the new vaccination for wisdom teeth.
