If you are a coffee or red wine lover, your teeth may look yellower than they used to be in the past. Many people in this situation turn to whitening creams or strips in the hope of achieving whiter teeth, but there is little these products can do if the stains are deep. In these cases, LED teeth whitening will help you obtain the best results.

What is LED teeth whitening?

Teeth whitening with led light is a cosmetic procedure used to lighten the color of your teeth and achieve a whiter, brighter smile. This treatment is performed both at home and in dental offices and uses LED light technology to activate a whitening gel that is applied to the teeth.

It is important to note that LED teeth whitening is not permanent, as teeth can become stained over time due to factors such as diet, tobacco use, and poor oral hygiene. However, with good dental care and habits, whitening results can last several months or even years.

How to do teeth whitening with LED light

Generally, to use of teeth whitening with led light devices is done as follows:

*Preparation: Clean your teeth by brushing them gently before starting the treatment. This will help remove food debris and dental plaque.

*Apply the whitening gel: Follow the manufacturer’s instructions to apply the whitening gel to the tray of the LED light device. Make sure to distribute the gel evenly on the front of the tray, where the teeth will be placed.

*Place the tray on your teeth: Insert the tray with the whitening gel into your mouth, making sure it fits properly and covers your teeth from the front. Avoid biting or biting hard on the tray to avoid damaging it.

*Turn on the LED Light Device: Once the tray is in place, turn on the LED Light Device according to the manufacturer’s instructions. The LED light will activate the whitening gel and speed up the whitening process. Keep the device on for the recommended time.

*Treatment duration: Treatment duration may vary depending on the kit and manufacturer’s instructions. It is generally recommended to use the device with LED light for 15-30 minutes a day, for several weeks.

*Aftercare: After each whitening session, remove the tray, rinse your mouth, and clean the tray according to the manufacturer’s instructions. Follow your dentist’s recommendations for post-whitening care, such as avoiding foods and drinks that can stain your teeth and maintaining good oral hygiene.

Advantages of LED teeth whitening

The main advantages of LED whitening are the following:

*Quick and effective procedure: the results are visible from the first session. A single session will be enough to lighten the shade of tooth enamel. The lamps we work with are designed to cover a very wide area so that all the teeth can be covered at the same time. 

*No discomfort: the use of the LED lamp reduces the amount of heat since it is a cold light. This produces less tooth sensitivity and reduces enamel damage.

*Grateful treatment: very visible results are achieved in a relatively easy way, with little effort.

*Promote dental hygiene: on the day of the session, your hygienist will teach you new eating and dental care habits. These guidelines will be key to maintaining the whiteness of your smile, but also to improving oral health.

Disadvantages of LED teeth whitening

LED teeth whitening can have the following drawbacks:

*Sensitivity during and after treatment. This is because the teeth suffer an increase in temperature as a result of light irradiation. If you suffer from hypersensitivity, do not worry, as it is a symptom that will subside in a short time.

*Dietary restrictions: you should try to follow a white diet, thus avoiding any type of coloring, whether natural or artificial. This is because, during this treatment, the pores of your tooth enamel tend to open and are more prone to staining. We must also avoid, during and after whitening, sugary drinks, the use of colored toothpaste or mouthwashes, and other bad habits such as smoking.

What are the phases of teeth whitening with LED light?

The first step to start teeth whitening is to go for a check-up and treat any type of pathology since it is necessary to have good oral health. Once the dentist has assessed the state of health and performed any necessary prior procedures, treatment can begin.

The next step will consist of doing a professional dental cleaning to remove all the tartar and accumulation of bacterial plaque effectively. 

At the next appointment, the session will be carried out with an LED light lamp. This procedure is normally carried out in a single visit. However, in patients who experience a lot of dental sensitivity, the cold light lamp session will be done in several phases.

During this session, separators will be placed in the patient’s mouth and the gums and lips will be isolated with a polymerizing gel. In this way, the mucosa will be completely isolated and protected. As we have previously mentioned, if the mucosa comes into contact with the whitening gel, irritations and burns may appear.

Next, the whitening agent – hydrogen peroxide or carbamide peroxide – is applied to the tooth surface, and the cold light lamp is placed for about 45 minutes, divided into three cycles of fifteen minutes each. 

This means that there is a pause every fifteen minutes, during which the whitening gel is wiped off and reapplied again before the next cycle.

After this time, the remains of the whitening product and the polymerizing gel will be removed from the surface of the teeth. And, of course, you can see the results of the treatment, since the whitening effect is noticeable from the first day.

Guide to choosing the best way to do teeth whitening with LED:

Aside from considering your budget, there are other factors you should take into account when purchasing an LED teeth whitening device.

How long does teeth whitening with LED light last?

The duration of LED teeth whitening can vary depending on the kit and manufacturer’s instructions, as well as the individual needs of each person. In general, it is recommended to use the device with LED light for 15-30 minutes a day, for several weeks, to achieve visible results.

It is important to note that teeth whitening is not a permanent procedure, as teeth can become stained over time due to exposure to foods and beverages that can cause stains, such as coffee, tea, and red wine, among others. Additionally, oral hygiene habits, such as properly brushing and flossing, can also influence how long your results last.

After completing LED teeth whitening, it is advisable to follow your dentist’s instructions regarding aftercare and make regular visits to maintain oral health and touch up the whitening if necessary.

It should be noted that the exact duration of LED whitening can vary from person to person, and it is important to follow the manufacturer’s instructions and consult a dentist for optimal and safe results.

Do teeth whiteners with LED lights work?

Teeth whiteners with LED lights are a popular method for whitening teeth at home. These kits usually contain a whitening gel that is applied to the teeth and an LED light that is placed in front of the mouth during the treatment. The idea behind this approach is that the LED light speeds up the teeth whitening process.

In general, teeth whiteners with LED lights can help reduce stains on your teeth and improve their appearance. However, it is important to note that results may vary depending on the person and the severity of the spots.

Some studies have suggested that LED light may have a positive effect on teeth whitening by increasing the effectiveness of the whitening gel. However, other studies have shown mixed results and there is no definitive scientific consensus on the effectiveness of these LED lights in teeth whitening.

Characteristics of LED teeth whitening

As we have already mentioned, LED teeth whitening is a procedure that is as fast as it is effective. Furthermore, if patients follow good oral hygiene after whitening, the results of the treatment are very long-lasting.

Professional teeth whitening, and especially cold light teeth whitening, is the only method that has scientifically proven its effectiveness in many clinical trials.

None of this applies to “whitening products” sold in pharmacies and para pharmacies. Although they are based on the same molecule as professional whitening gels, their concentration is so low that the whitening effect on teeth is practically imperceptible. Furthermore, they are products whose use is not customizable (made to measure) nor is it supervised by a dentist.
