Why darker colors make teeth look whiter
It is contrast. Next to a deep, cool color, natural enamel looks lighter. Next to white or yellow, the same teeth look warmer and duller. That is why orthodontic guides keep recommending navy, dark purple and deep teal to people who want a brighter-looking smile.
Braces colors to avoid if you want whiter-looking teeth
None of these colors is wrong. They just work against a brighter look.
- White: looks crisp on day one, but makes yellow tones in the enamel stand out.
- Clear: discreet at first, then picks up color from coffee, tea, curry or tomato sauce.
- Yellow and gold: blend with warm tones in the teeth instead of contrasting with them.
- Brown, beige and some greens: can be mistaken for food caught in the brackets.
- Black: gives strong contrast, but some people feel it looks like gaps or trapped food.
Staining between visits
Elastic ties are worn for weeks at a time. A laboratory study of tooth-colored elastic ties found that black tea, wine and coffee caused the most color change and that every shade tested changed to some degree. Darker ties hide that change better than clear or pale ones.
Check before you choose
Screens and lighting change how a color looks, so compare shades on the same smile and keep notes of the ones you like. In the Braces Colors picker, navy and silver are presets; use the custom color to try dark purple, burgundy or forest green.
