Front teeth that used to be straight and are now flaring forward, or developing new gaps, are telling you something about the foundation underneath. This doesn’t happen for no reason.
The usual causes:
1. Bone loss from gum disease. The front teeth lose support and start to drift outward.
2. Missing back teeth. When molars are gone, the front teeth take chewing force they weren’t built for, and they get pushed forward.
3. Grinding or clenching, which adds force on top of everything else.
4. The tongue pressing on the back of the front teeth.
Why it’s worth catching early: once teeth start moving, they rarely stop on their own. The spaces trap food, gums get irritated, and the movement speeds up.
What fixes it depends on the cause:
1. Treating gum disease first, always.
2. Replacing missing back teeth, so the front teeth stop carrying the load.
3. Sometimes aligners to move the teeth back, followed by a retainer.
4. A night guard if you grind.
The part people don’t expect: the fix is often in the back of the mouth, not the front.
If yours are moving, bring an older photo to your next visit. Seeing how far they’ve drifted helps us find the cause.
