Whitening with Led Light

Whitening with laser and with LED light. Professional whitening can be improved by exposing dental arches to special light sources, such as plasma light, ultraviolet light or laser light. Apparently, this type of lamps have the ability to accelerate the penetration effect of peroxide and the splitting of the joints of the molecules of the pigments inside. Do not worry, the dentist knows how to use the tooth whitening kit with led light.

How Does Teeth Whitening Work with the Light

This effect can be conditioned by several factors, including the heating of the gel by high intensity light sources, the initiation of a reaction by a photoactivator in the bleaching product and a reinforcement of the effect through a chemical catalyst present in the the bleaching agent.

The clinical approach of this method is based on the increase of the bleaching effect of the product that, in turn, must lead to a reduction of the treatment time in the dental clinic.
The purpose of the bleaching treatment with laser and special lamps (such as LED light) is to find a system that is able to accelerate the effect of peroxides in order to reinforce the bleach, without increasing the temperature of the tooth or without causing injuries in the soft tissues. This is achieved concretely with the light absorbed selectively by the gel applied on the teeth.

Laboratory studies have been carried out to investigate the increase in temperature of the teeth during bleaching with different light sources. In these studies it has been demonstrated that the LED light generates the lowest temperature increase, being comparable with a treatment of the teeth with hydrogen peroxide at 35% without photoactivation.

It is known that in some cases, the use of the teeth whitening technique can cause temporary hypersensitivity in some patients. In these cases it is advisable to stop the treatment for a few days and then resume it.

Therefore, it is important to know perfectly whitening systems that can be used, because only then can possible complications be reduced.

There are factors that can influence hypersensitivity, such as the concentration of the product, the time of application of the product and the chosen activation method. A correct handling of all these variables can avoid undesirable side effects.

Side effects of laser whitening

The specialists stress that tooth whitening is a painless and easy to achieve treatment. However, it can result in a series of adverse aspects that we will detail below.

Tooth sensitivity
Dental sensitivity during treatment is the most frequent side effect among patients who address it. This is due to the penetration of the bleaching agent through the pores of the enamel to the dentine.

The use of products in poor condition or with a concentration higher than the recommended can cause burns to the soft tissues of the mouth – lip, gums – or cause abrasion of tooth enamel.

In any case, this side effect is not frequent in the case of whitening performed under the supervision of a dentist.

Allergic reactions
Very rarely, the patient exhibits an allergic reaction to the components of the bleaching agents. In that case, the procedure should be interrupted immediately.

Gum irritation
During the treatment, the gums may be exposed to the action of the bleaching agent and, therefore, suffer some irritation. It will be sent when the product stops being in contact with the soft tissues.
