Teeth whitening brightens smiles, and orthodontic braces align teeth. Many individuals undergoing orthodontic treatment wonder if they can combine these two common dental procedures. Understanding the considerations for teeth whitening during braces is important for achieving optimal results and maintaining oral health. The interaction between whitening agents and orthodontic appliances requires careful consideration to avoid unintended outcomes.
Why Whitening During Braces is Problematic
Traditional teeth whitening methods are generally not recommended while wearing braces due to several factors. A primary concern is uneven whitening. Brackets and bonding material block the whitening agent from reaching the enamel underneath. This can result in noticeable discolored spots or a patchy appearance once braces are removed, as exposed areas whiten but covered areas do not. Whitening toothpaste can also cause uneven cleaning around brackets, leading to inconsistencies in tooth color.
Another significant issue is increased tooth sensitivity. Orthodontic treatment itself can cause teeth to become sensitive. Introducing whitening agents, which often contain peroxides, can exacerbate this sensitivity and potentially irritate the gums. Studies have also shown that certain bleaching procedures can reduce the bond strength of orthodontic brackets. The whitening agent cannot effectively reach the entire tooth surface, leading to suboptimal and uneven results.
Optimal Timing for Teeth Whitening
The most advantageous time to undergo teeth whitening is after orthodontic treatment concludes and braces have been removed. At this point, the entire tooth surface is fully exposed, allowing for uniform application of whitening agents and consistent results. Any sensitivity from orthodontic tooth movement usually subsides within a few weeks to months, making the whitening process more comfortable. Orthodontists commonly advise waiting a minimum of a few weeks, and often up to six months, after brace removal to allow the enamel to heal and teeth to stabilize.
While it is possible to whiten teeth before getting braces, this approach can also lead to uneven shading later on. If teeth are whitened before braces are applied and then shift during treatment, previously overlapped or unexposed areas might not have whitened evenly. Once braces are off, both professional in-office whitening and at-home options are available, with professional treatments often being more effective and safer due to dental supervision.
Maintaining Tooth Whiteness During Orthodontic Treatment
While traditional whitening is best reserved for after braces, individuals can take proactive steps to maintain tooth whiteness during orthodontic treatment. Practicing excellent oral hygiene is important. This includes meticulous brushing after every meal to remove food particles and plaque that can accumulate around brackets and wires. Using a soft-bristled or orthodontic toothbrush, along with interdental brushes or a water flosser, can help clean hard-to-reach areas effectively. Daily flossing is also crucial for removing plaque between teeth and along the gumline, preventing discoloration and promoting gum health.
Dietary considerations also play a significant role in preventing stains. Limiting the consumption of stain-causing foods and beverages, such as coffee, tea, dark sodas, berries, and tomato-based sauces, can help preserve tooth color. If these items are consumed, rinsing the mouth with water immediately afterward can help minimize their staining effect.
Regular dental cleanings are also important for maintaining tooth whiteness and overall oral health with braces. Professional cleanings help remove surface stains, plaque, and tartar that can build up around orthodontic appliances. Dentists may advise more frequent cleanings, sometimes every three to four months, due to the increased challenges of cleaning around braces. Avoiding habits like smoking, which can significantly stain teeth, further supports a brighter smile throughout the orthodontic journey.
