From my own personal experience, I’ll say “be afraid…be very afraid” about those wisdom teeth butting in. I know this won’t make you more comfortable about your situation, but there is the likelihood that those wisdom teeth will remove at least the rearmost molars when and if, in fact, they erupt. This is what is currently in progress in my own mouth. My wisdom teeth are erupting through the gums, and simultaneously are crushing my rearmost molars and the molars in front of those right out of my head, quite painfully I might add. This has got to be the worst two-for-one deal I’ve ever received.
Personally, I’d advise visiting your local orthodontal specialist re: removing those yet-to-be-troublesome wisdom teeth in the interest of saving those comfortably out of alignment molars.
Wisdom teeth are true to their name, they further reinforce the wisdom of hindsight, and that is “I should have had those damn things removed before they replaced my molars!”
Best of luck!
