Is it normal for teeth to shift?

YES, BUT...: It's normal (occurs quite often) but is not "correct". Teeth should be in the right position and place. Consult your dentist to treat and level/align your teeth (orthodontia).

Teeth shift: Like all parts of our body. Everything changes in time. This is called maturation, or aging.

AT 11 SHIFTING TEETH: At this age losing baby teeth may be happening, and permanent teeth growing in where baby teeth where lost, if this is what is ment by shifting this is normal. However, if what your concern is shifting of the permanent teeth after they have grown in this could be normal such as spaces that are now getting smaller, the best answer to "is it normal for teeth to shift", is to see an orthodontist.

Perhaps: Teeth shift and change over our lifetime. At 11-12 we are seeing the loss of the last baby teeth and the eruption af most of the permanent teeth. If teeth are out of position, however, the shifting may be pathologic rather that physiologic. Simply put, if you have any questions have your occlusion (the way your teeth align and come together) checked by an orthodontist.

Absolutely!: Teeth are constantly moving. That is why it is very important to wear your retainers after orthodontic treatment.

Yes: Teeth will naturally shift throughout your life without a retainer.

Thanks for asking!: I wouldn't call it 'normal' but it is surely possible, especially if you have had braces in the past and haven't been wearing retainers regularly.
