Shifting or Crowded Teeth: Why It Happens in Atlanta Adults
Teeth Move Throughout Life
Adult teeth can shift slowly with age, after braces, or when a tooth is missing. Shifting can also be a sign of gum disease or grinding, so new gaps or crowding should be examined before any straightening. Once the gums and bite are healthy, clear aligners such as SureSmile can move teeth back into place.
A new gap between front teeth deserves a gum check first.
What Can Cause Teeth to Shift?
Some causes are harmless and some need treatment first.
| Possible cause | What you may notice | How it's treated | Learn more |
|---|---|---|---|
| Natural changes with age | Slow crowding of the lower front teeth | Monitoring or aligners | SureSmile Clear Aligners |
| Not wearing a retainer after braces | Teeth drifting back toward their old position | Aligners, then a retainer | SureSmile Clear Aligners |
| Missing tooth | Neighboring teeth tipping into the space | Tooth replacement; bone grafting may help | Tooth Replacement |
| Gum disease | New gaps, loose teeth, bleeding | Periodontal therapy before any tooth movement | Periodontal Therapy |
| Grinding or clenching | Shifting with wear and a sore jaw | Protective appliance | Fillings |
This table describes common patterns, not a diagnosis. Your examination determines the cause and the right care.
