The list of products that discolor teeth is almost endless, but finding a single teeth whitening product that works as expected can be difficult. Most whitening products consist of physical applications, such as strips that adhere to enamel. In many cases, these products only moderately improve tooth color. They could also damage enamel and irritate sensitive gums. That is why people who need teeth whitening are turning to White by Light-an advanced light therapy that uses LED lamps to remove accumulations that cause teeth to appear dull.

Using light to improve tooth color is a recent development in cosmetic technology. If you have questions regarding the treatment, the answers below can help.

How does the treatment work?

The treatment uses state-of-the-art technology to produce high-intensity light that improves tooth color without overheating the mouth. Before being exposed to the light, teeth are covered with a special whitening gel. Combined together, the light and gel remove stains and accumulations that cause teeth to appear dull and yellow. When it is performed properly, the treatment can leave teeth several shades whiter.

How long does the treatment take?

The treatment takes roughly twenty minutes, making it ideal for salon owners to offer as a beauty treatment. For the customer, receiving brighter teeth in twenty minutes is more convenient than using applications that are worn for hours at a time and take weeks to produce a noticeable result.

How long does the treatment last?

The length of time teeth remain white depends on the dental and dietary habits of the customer. If proper dentition is practiced, and products that tarnish enamel are not used or consumed, teeth can look remarkably unchanged for months at a time, or even longer.

Can the treatment be administered at home?

Yes. The White by Light treatment can be administered in the comfort of your home. Performing the treatment on your own is more cost effective than receiving it from a salon or dental office that performs advanced light therapy.

Is the treatment safer than other whitening treatments?

LED technology is perhaps the safest tooth whitening technology available. Unlike bleaching agents that can erode enamel and inflame the gums, the therapy does not expose teeth to corrosive substances. Instead, it targets the discoloration that makes teeth appear yellow without damaging the structure of teeth.


The pursuit of a brighter smile is not new, but only recently have treatments become available that improve tooth color without damaging the tooth structure. One such treatment is the White by Light procedure, which uses advanced light therapy in combination with a gel to remove the dull, yellowish pigments that make it embarrassing to smile.

If you need to brighten your teeth, do not waste time on ineffective products that could potentially harm your enamel and gums. Instead, visit a salon that uses light therapy to improve tooth color, or purchase a therapy system and use it in the comfort of your own home.
