After maxillary expansion and the extraction of two molars, will the spaces between the teeth gradually increase once orthodontic treatment is completed?

Doctor: Hello! I am undergoing orthodontic treatment.
The doctor recommended first performing maxillary expansion and extracting the second molars on both sides of the upper arch to create space, followed by Invisalign treatment.
I would like to ask:
1.
After maxillary expansion and tooth extraction, once the orthodontic treatment is completed, if I do not wear retainers, will the gaps in my upper teeth gradually become larger again?
2.
Additionally, after completing the orthodontic treatment, if I do not wear retainers, is the likelihood of the gaps becoming larger greater than if I had not undergone maxillary expansion?
Thank you for your guidance!

Hello: Typically, after orthodontic treatment is completed, the vast majority of cases will use retainers to stabilize the teeth and prevent them from shifting in the short term.
Retainers can also be placed on the lingual side to avoid affecting aesthetics, and they can be made as removable devices.
It is recommended to wait until the treatment is finished to discuss this with your dentist.

When it comes to orthodontic treatment, particularly involving upper jaw expansion and tooth extraction, there are several factors to consider regarding the potential for teeth gaps to widen after treatment.
1. Understanding Tooth Movement and Retention: After orthodontic treatment, the primary concern is the stability of the results achieved. Teeth have a natural tendency to shift back to their original positions, a phenomenon known as "relapse." This is particularly true if retainers are not used consistently after the active phase of orthodontic treatment. If you undergo upper jaw expansion and extraction of the second molars, the gaps created will be closed during the orthodontic process. However, if retainers are not worn post-treatment, there is a risk that the gaps may reopen over time.

2. Impact of Upper Jaw Expansion: Upper jaw expansion can create additional space in the dental arch, which can help in aligning the teeth properly. However, if the expansion is significant, it may lead to changes in the way the teeth fit together, potentially increasing the likelihood of gaps if the teeth are not properly retained afterward. The expansion itself does not directly cause gaps to widen, but the changes in tooth position and the absence of retention can lead to a situation where gaps may appear larger over time.

3. Comparative Risk of Gaps: If you do not wear retainers after completing your orthodontic treatment, the likelihood of gaps widening may indeed be higher after upper jaw expansion and tooth extraction compared to a scenario where no expansion was performed. This is because the structural changes in the dental arch from expansion can create a different dynamic in how the teeth interact with each other. Without the stabilizing effect of retainers, the teeth may drift, leading to the reopening of gaps.

4. Importance of Retainers: Retainers are crucial in maintaining the position of your teeth after orthodontic treatment. They help to stabilize the teeth in their new positions and prevent them from shifting back. It is essential to follow your orthodontist's recommendations regarding the duration and frequency of retainer wear. Typically, after the active phase of treatment, you may be advised to wear retainers full-time for a period, followed by part-time wear for several months or even years.

5. Regular Follow-ups: Regular follow-up appointments with your orthodontist are vital to monitor the stability of your treatment results. If you notice any changes in your teeth alignment or gaps, it is important to communicate these concerns with your orthodontist promptly. They can assess the situation and recommend any necessary adjustments or additional retention strategies.

In conclusion, while upper jaw expansion and tooth extraction can effectively create space for orthodontic correction, the long-term stability of your results largely depends on the consistent use of retainers. Without proper retention, there is a risk that gaps may reappear, potentially more so after expansion due to the altered dynamics of the dental arch. Always consult with your orthodontist for personalized advice and to ensure the best outcomes for your dental health.
