Instant white tooth paints work by whitening teeth using a temporary paint that is applied to the teeth in the same way as nail polish is applied to the nails. NuDent Whiten-10, a brand of available tooth paint, claims it does not affect the integrity of the teeth and is safe to use on dental work such as crowns, veneers and dentures, reports Dr. Bicuspid's website.
There are many tooth paints, polishes, gels and whitening strips available on the market. Depending on the extent of tooth stains and the condition of the tooth enamel, each provide varying degrees of long-term benefits, according to Web M.D. Tooth paint is a temporary white cover-up for teeth and will whiten teeth by applying a coat directly onto the tooth.
