Can teeth shift over time?
Shifting teeth in children
Teeth begin to develop during pregnancy. Even though they are not yet visible in a child’s mouth, both baby teeth and permanent teeth are already present in the jaw. It takes some time before the first teeth erupt. Baby teeth are often jokingly referred to as “placeholders” for the permanent teeth. When a baby tooth has served its purpose and falls out, it makes room for the next tooth to emerge.
However, accidents or illnesses can sometimes make it necessary to remove teeth prematurely. In such cases, the remaining baby teeth have the opportunity to move and narrow the space that has been created. Unfortunately, this can lead to the succeeding permanent tooth erupting in an incorrect or crooked position.
Tooth movement in adulthood
In adults, the reasons for tooth movement are even more varied. Possible causes include:
- Accidents: After an accident, teeth may become loose or the jaw may be injured. In such cases, a dentist or orthodontist should stabilise the teeth in the correct position.
- Teeth grinding: Teeth grinding is not just a habit, but a medical condition. Bruxism can cause changes in the position of certain teeth within the jaw. Many people grind or clench their teeth, especially during periods of stress or at night.
- Tooth loss: As with baby teeth, permanent teeth can drift or tilt into existing gaps. This movement alters the bite and can significantly complicate future restorative treatments such as dentures or implants.
- Untreated gum disease: Periodontal conditions, such as periodontitis, can lead to insufficient anchorage of the teeth in the bone, allowing the entire dentition to shift over time.
- Natural tooth movement: Even after orthodontic treatment, the lower front teeth can shift in adulthood. Mesial drift, where the back teeth naturally move toward the centre of the jaw, is a normal process. The common belief that erupting wisdom teeth cause crowding of the other teeth is largely a misconception.
After orthodontic treatment
In the first years following orthodontic treatment, the teeth are still prone to significant movement and may attempt to return to their original positions. This can result in renewed misalignment. For this reason, orthodontists recommend finishing treatment with a retainer.
A retainer is usually bonded behind the front teeth and consists of a thin wire that is fixed in place with adhesive. In some cases, a removable retainer is also prescribed to further prevent tooth movement and ensure long-term stability. Patient compliance is essential. Not wearing the retainer or removable appliance can undo the entire success of the orthodontic correction.

Possible consequences of tooth misalignment
Misaligned teeth can lead to pain and dysfunction in the jaw joints and chewing muscles. Problems with posture, as well as headaches and neck pain, can also occur. After orthodontic treatment, patients often notice a significant improvement in these symptoms.
Conclusion
Straight teeth are the goal for many people, but a perfectly aligned dentition is rare. In some cases, orthodontic treatment is necessary to correct tooth misalignment. Particularly during the mixed dentition phase, when permanent teeth replace baby teeth, crowding can cause teeth to rotate or shift. At this stage, correction is already possible at a young age – even before the permanent dentition has fully developed.
Early treatment of jaw and dental problems is generally less complex than treatment later in life. During growth phases, jaw development can be guided through targeted orthodontic measures, which is no longer possible in adulthood. For this reason, it is important to detect and treat jaw and dental misalignments as early as possible in order to avoid future complications and more extensive interventions.
Frequently asked questions
What causes teeth to shift?
There are many possible triggers. Teeth grinding (bruxism), an accident, tooth loss, or illness can all cause changes in the position of the teeth. Orthodontic appliances such as braces or aligners can help correct these changes.
Why do teeth shift in adults?
Unlike bones, teeth are not fixed in one rigid position. Under unfavourable conditions, they can move throughout life. Periodontal disease (gum disease) can contribute, as can gaps from missing teeth or trauma after an accident. If you notice your teeth shifting, it is advisable to see a dentist or orthodontist.
