Why Teeth Shifts After Braces and How to Prevent It
Sep 29, 2024
Achieving a perfect smile with braces is a significant investment of money and time. However, many individuals find that their teeth gradually shift back to their original positions years after completing orthodontic treatment. This occurrence can be incredibly frustrating and disheartening, particularly after enduring the discomfort and dedication associated with wearing braces over many years.
The Nature of Teeth Movement
To understand why teeth shift after braces, it is important to understand the fundamental of tooth movement. Teeth are held in place by the periodontal ligament, a group of fibrous connective tissues that attach the tooth roots to the surrounding alveolar bone. These ligaments are elastic, allowing teeth to move gradually in response to consistent pressure or force.
During orthodontic treatment, braces apply controlled forces to the teeth, causing them to shift into their desired positions over time.
Once the braces are removed, the teeth are no longer subject to these external forces, and the periodontal ligaments can slowly revert to their original state, leading to potential shifting.
Common Causes of Teeth Shifting After Braces
Unfortunately, teeth shifting after braces is a common issue that many people experience. This can happen due to several factors:
- Age
As we get older, our bodies experience a range of changes, that includes changes in our teeth and jawbones. Over time, the periodontal ligaments that secure our teeth may become less flexible, making it easier for teeth to move.The density of the jawbone tends to decrease with age, resulting in reduced tooth support.
- Oral Habits – Teeth Grinding
Habits, like teeth grinding, known as (bruxism), clenching, or applying excessive pressure on the teeth while chewing can gradually alter the positioning of your teeth. The loss of a tooth can create a gap, prompting neighboring teeth to shift and fill the vacant space. - Gum Health
Neglecting oral hygiene can result in gum disease, which weakens the structures that support teeth. When the gums are compromised, teeth can shift more easily. - Periodontal Disease
Periodontal disease, also known as gum disease, can weaken the supporting structures that hold teeth in place. As the disease progresses, it can lead to bone loss and tooth mobility, allowing teeth to shift more easily. - Injuries
Accidents or injuries that damage the jaw, teeth, or surrounding structures can disrupt the alignment achieved through orthodontic treatment, causing teeth to shift out of place.
Signs of Teeth Shifting After Braces
Recognising the signs of shifting teeth is crucial for addressing the issue promptly. Here are some common indicators to look out for.
- Gaps or spaces between teeth that were previously closed
- Retainers no longer fitting
- Overlapping or crowding of teeth
- Changes in your bite alignment or the way your teeth come together
- Increased difficulty in flossing or cleaning between certain teeth
- Discomfort or tenderness in the jaw or teeth
If you notice any of these signs, request another consultation with an orthodontist for further evaluation.
How to Prevent Your Teeth from Shifting After Braces
While some degree of shifting may be unavoidable, there are preventative measures you can take to minimise the risk.
- Fixed Retainers
For individuals who struggle with compliance or have a high risk of relapse, fixed or permanent retainers may be recommended. These retainers are bonded to the back of the teeth, providing a discreet and reliable solution to maintain tooth alignment. While fixed retainers require more diligent oral hygiene and regular check-ups, they offer peace of mind by eliminating the risk of forgetting to wear a removable retainer. Fixed retainers are normally installed at the end of the orthodontic treatment. - Removable Retainers
Most orthodontic patients receive removable retainers, typically made of clear plastic or a combination of plastic and wire. These retainers are worn full time for the first few months after treatment and then gradually transitioned to nighttime wear.It’s crucial to follow your orthodontist’s instructions regarding retainer wear, as failing to do so can quickly undo the hard earned results of your orthodontic treatment.
- Mouthguards
Mouthguards, typically associated with sports and nighttime teeth grinding (bruxism), can also play a role in preserving your post braces smile. These protective devices create a barrier between your upper and lower teeth, absorbing the impact of clenching or grinding forces that could potentially shift your teeth over time. - Maintaining Optimal Oral Hygiene
Proper oral hygiene is crucial for maintaining the health of your gums and supporting structures, which play a vital role in keeping your teeth in their ideal positions. Regular brushing, flossing, and professional dental cleanings can help prevent gum disease and ensure the longevity of your straight smile. - Addressing Underlying Medical Conditions
If you have an underlying medical condition that may contribute to tooth shifting, it’s essential to work closely with your healthcare providers to manage the condition effectively. Controlling conditions like diabetes or addressing hormonal imbalances can help maintain the stability of your teeth and prevent excessive movement.
Conclusion
Although it may be discouraging to consider the possibility of teeth shifting following orthodontic treatment, it is crucial to keep in mind that this is a normal process that can be controlled with proper care and guidance.
By understanding the underlying causes of this phenomenon and taking proactive measures to preserve your smile, you can continue to experience the advantages of your orthodontic treatment in the long run.
