Article Contains Natural Process of Teeth Movement Causes of Crooked Teeth Managing Crooked Teeth Impacts of Teeth Shifting Natural Process of Teeth Movement Our teeth are natural wanderers as we age. Over time, our gums and jawbone, which usually keep our teeth in check, start losing their grip. This can lead to those pesky crooked teeth or gaps that seem to appear out of nowhere. Blame it on the changing structures in our mouths as we add more candles to the birthday cake. Here’s a rundown of what happens with our teeth over the years: Age GroupNatural Changes20s-30sBarely any movement; things are mostly steady40s-50sGums and jawbone begin to slacken60s and olderMore movement; crooked teeth and gaps more likely Contributing Factors to Crooked Teeth Besides natural wear and tear, a few other culprits can make your teeth shift. Gum Disease: This tricky condition loosens the hold between your teeth and gums. As the gums pull back, teeth get wobbly and can shuffle around, creating uneven spacing (1). Jawbone Growth: As surprising as it is, our jawbones may keep growing, especially after 50. This can make those lower front teeth tip forward, causing crowding and messing with the alignment of our bite (1). Tooth Loss: Missing teeth usually means the neighboring ones make a run for it towards the open space. This migration can cause crowding, change your bite, and leave noticeable gaps that weren’t there before. Ignoring these changes can lead to a whole heap of trouble, like crooked bites, jaw disorders, more cavities, or even losing more teeth. Being in the know about what’s natural and what adds to the mix can help us keep our smile intact as we age. Interested in related curiosities?
