The color seen on braces comes from small elastic rings, known as ligatures, which secure the archwire into the bracket slot. Choosing purple for these elastics is a popular aesthetic choice, allowing personalization of orthodontic treatment. The visual effect varies significantly depending on the specific shade selected, ranging from a subtle hint of color to a vibrant display. Since the elastics are replaced during routine adjustment appointments, this color choice is temporary, offering the chance to change the appearance every few weeks.
The Spectrum of Purple Shades
Purple elastics are available across a broad spectrum, and the darkness of the pigment dramatically influences their final appearance against the teeth. Lighter shades, such as lavender or lilac, present a softer, more pastel appearance, often blending subtly with the smile. These delicate hues can be a gentle accent, but they may also appear faded or slightly off-white under certain indoor lighting conditions.
In contrast, choosing a deep violet, royal purple, or plum shade offers maximum color saturation and visibility. These darker tones create a strong contrast against the natural color of the teeth. This contrast can have the desirable effect of making the teeth appear whiter and brighter. The intensity of a dark purple ensures the color is clearly noticeable and provides a bold look throughout the weeks between orthodontic visits.
Factors That Change the Look of Purple
The perceived appearance of the purple elastics is highly influenced by the surrounding oral environment and external factors. The natural color of the teeth, which often has subtle yellowish or ivory undertones, affects how the purple is seen. Lighter purple bands placed on teeth with a warmer natural tone may appear to absorb some of that yellow, making the bands look less vibrant or even discolored faster.
The skin tone and lip color of the wearer also play a significant role in the overall presentation. For individuals with fair skin, cooler purple shades like lilac can complement their complexion. Those with darker or olive skin tones can often wear deeper, jewel-toned violets with great vibrancy. The contrast created by the purple against the skin and lips can either enhance or diminish the color’s perceived intensity. Furthermore, the lighting environment, such as bright natural daylight compared to warm indoor incandescent light, alters the reflection and perception of the purple hue.
Maintaining the Color
The elastic ligatures are made of a porous material, making them susceptible to absorbing pigments from foods and beverages. This absorption potentially alters the purple color over time. Lighter shades, including lavender and pastel purples, are particularly prone to staining and discoloration. Staining culprits like coffee, black tea, red wine, dark sodas, and foods containing turmeric can cause the purple bands to take on a yellowish or brownish tint.
Darker purple shades are more resistant to showing visible stains and are recommended for those concerned about color retention. While no elastic is entirely stain-proof, maintaining diligent oral hygiene, including brushing after meals, helps remove staining agents before they set into the porous material. Despite best efforts, the color will naturally dull slightly over the course of the weeks between appointments before replacement.
