Why Do My Teeth Shift as I Get Older?

It is a common misconception that teeth only move when you are a teenager wearing braces. In reality, your teeth are constantly under pressure from speaking, chewing, and the natural aging of your jawbone. Over time, this can cause "mesial drift," where teeth slowly move toward the front of your mouth, leading to new crowding or gaps.

Bone loss is another factor. As we age, the bone that supports our teeth can naturally recede, especially if gum disease is present. With less "foundation" to hold them in place, teeth are more likely to shift. If you wore braces in the past but stopped wearing your retainer, your teeth will also attempt to move back toward their original, crooked positions.

Shifting isn't just a cosmetic issue. When teeth overlap, they become much harder to clean, which increases your risk of cavities and gum disease in those tight spots. It can also change your bite, leading to jaw pain or uneven wear on your enamel.

The best way to prevent shifting is to maintain excellent gum health and wear a retainer if you have one. If you notice a change in your bite, it is important to address it early before the movement becomes more difficult to correct.
