Have you noticed gaps forming, teeth turning slightly, or a change in your bite? Teeth shifting is more common than you might think and it can happen at any age. Even if you’ve had braces, your teeth can still move over time.
This guide covers the most common reasons for shifting teeth, the risks of leaving it untreated, and how to stop or reverse the problem.
Why Do Teeth Shift Over Time?
Teeth don’t always move suddenly. In many cases, it’s a slow process caused by natural changes in your body, bite, or dental habits. Some of the most common causes include:
- Aging. As you get older, bone density decreases and gum support weakens, making it easier for teeth to move.
- Tooth loss. When a tooth is missing, the teeth around it often drift or tilt into the empty space.
- Grinding or clenching. Constant pressure from jaw clenching or grinding can push teeth out of position.
- Gum disease. When gum tissue or bone is lost, teeth no longer have the support they need to stay in place.
- Jaw changes. Subtle shifts in the jawbone can change how your teeth fit together.
- Not wearing your retainer. Teeth often relapse after orthodontic treatment if retainers are not worn regularly.
Signs Your Teeth May Be Shifting
Many people don’t notice their teeth shifting until there’s a visible change. Look for these early signs:
- Small gaps forming between teeth
- Crowding or overlapping, especially in the front teeth
- A change in how your bite feels when chewing
- Retainer no longer fits properly
- Soreness or tightness in your jaw
If you’ve asked yourself why are my teeth shifting, these signs may offer the answer.
Risks of Ignoring Shifting Teeth
Teeth that are out of alignment can lead to more than cosmetic concerns. Some of the most common complications include:
- Uneven wear on tooth surfaces
- Jaw pain or tension
- Difficulty chewing or speaking clearly
- Increased risk of cavities and gum disease due to hard-to-clean areas
- Tooth sensitivity caused by gum recession or root exposure
- Bone loss near unstable teeth
How to Stop or Reverse Teeth Shifting
If you act early, many cases of shifting teeth can be managed or corrected. Here are several ways to protect your smile:
Schedule a dental exam
A professional exam helps identify the cause of movement and allows your dentist to catch gum issues, bite problems, or missing teeth that may be contributing to the shift.
Wear a retainer or consider Invisalign
A custom retainer helps maintain your current tooth position. If your teeth have already shifted, clear aligners like Invisalign can gently move them back into place.
Address grinding and clenching
Wearing a nightguard helps protect your teeth from pressure caused by clenching and grinding, which is a leading cause of tooth movement.
Replace missing teeth
Dental implants, bridges, or partial dentures can prevent neighboring teeth from drifting into the open space left by a lost tooth.
Keep up with routine cleanings
Regular dental visits and cleanings help maintain gum health and bone structure, both of which are essential for keeping teeth stable.
Can Teeth Shift After Braces or Invisalign?
Yes. Even after successful orthodontic treatment, teeth can shift if you stop wearing your retainer. Over time, changes in your bite, habits like grinding, or jaw growth can cause teeth to move again. Many adults notice their teeth shifting years after treatment simply because they stopped wearing their retainer.
