If your teeth already look balanced and symmetrical, but are too yellow, brown, gray, or stained, then the best solution is teeth whitening. In two to four sittings teeth whitening can completely change your look. On the other hand, if your front teeth are a little too short, spaced unevenly, chipped, cracked, stained, filled with all kinds of fillings, or your teeth genetic make-up was just not as good as the rest of your genetic make-up, then using dental veneers /laminates (preceded by orthodontic treatment if required) will definitely give you the best end result. If there are just isolated problems, but the rest of your teeth look great, then direct resin composite can easily correct this. Sometimes, we will bleach all teeth, and then use dental veneers or composite resin to improve localized areas, and match the new, whiter shade.
