Why Are My Teeth Moving Out of Position?

Posted on 3/3/2025 by Dan O'Leary DDS

Have you noticed your teeth shifting or becoming misaligned? You're not alone. Many adults experience teeth movement over time, causing concerns about aesthetics and oral health. Understanding the causes of shifting teeth can help you take proactive steps to maintain a healthy, beautiful smile.

What Causes Shifting Teeth?

Several factors can contribute to teeth movement, including:

•	Natural Aging: As we age, our teeth naturally wear down, causing them to shift. This is due to the loss of bone and gum tissue that support the teeth.
•	Missing Teeth: When teeth are lost, the remaining teeth can shift into the empty space. This can occur due to tooth decay, gum disease, or injury.
•	Restorative Dentistry: Crowns, bridges, and dentures can affect the alignment of surrounding teeth, especially if they are not properly fitted or maintained.
•	Orthodontic Treatment: Braces and other orthodontic appliances can move teeth into new positions, but this movement can continue even after treatment is complete.
•	Oral Habits: Habits like chewing on ice, biting fingernails, or using your teeth as tools can put pressure on your teeth, causing them to move.
•	Gum Disease: Gum disease can weaken the bone and tissue that support your teeth, making them more likely to move.
•	Bruxism: Grinding or clenching your teeth can put excessive force on your teeth, leading to movement.
•	Trauma: Injuries to the mouth can damage teeth and supporting structures, leading to shifting.
•	Genetics: Some people are more predisposed to teeth movement due to their genetics.

What Can I Do About Shifting Teeth?

If you notice your teeth moving, it's important to see your dentist. They can diagnose the cause of the movement and recommend the best course of treatment. Depending on the severity of the problem, treatment options may include:

•	Orthodontic Treatment: Braces, Invisalign, or other appliances can be used to move teeth back into their proper positions.
•	Restorative Dentistry: Crowns, bridges, or dentures can be used to replace missing teeth or improve the fit of existing restorations.
•	Gum Disease Treatment: If gum disease is the cause of the shifting, treatment will focus on controlling the infection and preventing further bone loss.
•	Habit Modification: If oral habits are contributing to the problem, your dentist will help you identify and break these habits.
•	Splinting: In some cases, teeth can be splinted together to prevent further movement.

Maintaining Healthy Teeth

Taking good care of your teeth is crucial for preventing shifting and maintaining a healthy smile. Here are some tips:

•	Brush your teeth twice a day with a fluoride toothpaste.
•	Floss daily to remove plaque and food debris between your teeth.
•	Visit your dentist for regular checkups and cleanings.
•	Avoid chewing on hard objects, like ice or fingernails.
•	Wear a mouthguard during sports or other activities that could injure your mouth.
•	If you grind your teeth at night, talk to your dentist about getting a night guard.

Conclusion

Teeth shifting can be a frustrating experience, but it's important to remember that it's a common problem with effective treatment options. By understanding the causes of shifting teeth and taking steps to prevent and address it, you can maintain a healthy and beautiful smile for years to come.
