Yes, they do: As we get older there are natural to get some changes in your bones. One such change is a narrowing of the lower jaw as the canines tip in slightly. This takes away some of the space for the lower incisors causing them to shift and become slightly crooked. See your dentist for more information and if your wisdom teeth fully erupted do not remove them.

During teen years lower jaw outgrows upper by about 3% causing lower incisors to tip back. Teeth try to erupt and drift toward the midline to compensate for tooth wear that we don't see with our modern refined diets. Tonsils/adenoids/back 1/3 of tongue shrink while at same time facial drape matures, producing backward pressure on teeth. See an Orthodontist now to stabilize your dentition.

Yes: During the last teenage growth spurt the lower jaw grows down and forward and can cause crowding of the bottom front teeth. This happens for both boys and girls, but usually to a greater degree in boys

Absolutely: There are many physiologic causes for this phenomenon. The crowding will get more severe, and at an increasingly rapid rate, as time goes on. See an Orthodontic Specialist NOW to stabilize your occlusion.

Tooth Movement: Yes, your teeth can move through out your lifetime. That is why when you complete your orthodontic treatment, retention is the MOST important part of treatment. If a patient does not wear retainers or have fixed retention, I can guarantee that teeth will move.
