Are there any side effects of laser teeth whitening?

Teeth whitening refers to the process of placing chemical oxidative bleaching drugs on the surface or inside of the teeth to react chemically with the teeth to whiten the color of the teeth themselves, or using objects to adhere to the surface of the teeth to cover the original color of the teeth and whiten the color of the teeth. So let’s take a look at the side effects of laser teeth whitening!

1. Laser Teeth Whitening

Laser teeth whitening works by using a laser whitening device to output a unique wavelength from a semiconductor to excite the whitening gel that has been applied to the tooth surface. The laser can then selectively act on the pigment particles in the teeth, catalyzing the gel to react with the pigment, thereby removing tartar. Laser teeth whitening has made a breakthrough in this regard. It does no damage to the teeth and greatly reduces the possibility of overheating or sensitivity of the teeth. Its effect is incomparable to that of ordinary teeth whitening methods.

II. Introduction

Laser teeth whitening is achieved by using a laser whitening device to output a unique wavelength of a semiconductor to excite the teeth whitening gel that has been applied to the tooth surface in advance. The laser can then selectively act on the pigment particles in the teeth, catalyzing the gel to react with the pigment, thereby removing tartar, plaque, pigments, smoke stains and soft stains, and restoring the teeth to whiteness. Teeth whitening experts say that, generally speaking, ordinary teeth whitening methods can only remove surface attachments on the teeth or cover up tooth discoloration, and cannot fundamentally change the original appearance of the teeth. Laser teeth whitening has made a breakthrough in this regard. It does no damage to the teeth and greatly reduces the possibility of overheating or sensitivity of the teeth. The effect is incomparable to that of ordinary teeth whitening methods.

3. Scope of application

1. Tetracycline Teeth

We all know that human teeth should be white and shiny. Some people have a mouth full of yellow teeth. This is because they took too many tetracycline drugs during infancy or during pregnancy and lactation, including tetracycline, oxytetracycline, chlortetracycline, demeclocycline and doxycycline. This class of drugs is a broad-spectrum antibiotic that is often used to control inflammation. After taking tetracycline drugs, they are absorbed through the gastrointestinal tract and maintain a certain concentration in the blood. They have a strong affinity with human calcium ions and, after combining with calcium, form a yellow complex of tetracycline calcium. If the crown is in the calcification stage of development, this complex is deposited on the crown, causing the erupted tooth to be underdeveloped and appear yellow. It is generally believed that the color of teeth caused by chlortetracycline is gray-brown, tetracycline and oxytetracycline are yellowish, and demeclocycline is the darkest yellow. In severe cases, there will be incomplete development of tooth enamel.

2. Yellow Teeth

Yellow teeth means that the teeth are yellow. There are three reasons for its formation: the first is mottled enamel, also known as fluorosis, which is caused by excessively high fluoride concentration in drinking water. When the fluoride concentration exceeds one part per million, it will affect the calcification process of the tooth germ, causing the tooth surface to turn yellow and uneven, with point-shaped or strip-shaped recessed defects. Mottled enamel often occurs during the calcification period of tooth development before the age of 5. The second type is tetracycline teeth, which are caused by frequent use of tetracycline during childhood. The third is smoking, which causes the yellow substance in tobacco to stick to the teeth.

Dental experts say that the laser whitening system has a magical whitening effect on adult melanin caused by tetracycline, as well as deep smoke stains and yellow teeth left by years of smoking. The laser teeth whitening system causes no pain to the patient during the teeth whitening process. Literature and clinical trials around the world have shown that this method does not harm the teeth, has no side effects, and does not harm the delicate gums. It only takes 1 hour. It saves time, effort, money and worry.

4. Advantages

1. Safety: Laser teeth whitening takes no more than 30 minutes to complete a full-mouth teeth whitening session, and the irradiation time for each tooth does not exceed 1 minute, thus greatly reducing the possibility of overheating or sensitivity of the teeth.

2. Painless: Laser teeth whitening treatment is painless, so no anesthesia is required. After treatment, due to the continuous effect of the drug, the teeth will feel a slight prickly sensation on the same day. In most cases, the pain will improve after a few hours on the same day and you will not feel any discomfort.

3. High efficiency: The efficiency of laser teeth whitening is 29.5 times that of simply using bleaching gel. The treatment handle designed according to ergonomic principles can treat four teeth at the same time. After each treatment, the teeth will increase by 3-4 degrees of whiteness. Generally, the whitening effect can last for 3-5 years.

4. Convenient: Laser teeth whitening is fully computer-controlled and easy to operate. The whole machine is small and exquisite, easy to move, convenient and fast.

There are so many advantages of laser teeth whitening. If you want to get rid of dark yellow teeth, you might as well try laser teeth whitening. With white teeth, we can have a beautiful smile.

5. Principle

The principle of laser teeth whitening is to apply the bleaching agent to the cleaned and pre-treated teeth, and then use laser to catalyze and decompose the bleaching agent to produce free oxygen atoms. The free oxygen atoms are highly active and can penetrate deep into the teeth, widely combine with pigment molecules and then release them.

Because laser whitening can fully open the dentinal tubules and enhance the permeability of the teeth, the effect of whitening drugs can be increased by 27 times. It is particularly suitable for the treatment of exogenous pigmented teeth. It can generally improve 2-4 shades, quickly restore the white luster, and present the natural original color of the teeth. It also has good effects on less serious tetracycline teeth and fluorosis. It is particularly worth mentioning that compared with other whitening technologies, laser whitening lasts longer, generally up to 3-5 years.

6. Notes

1. Precautions before surgery

(1) Introduce the steps, treatment time, prognosis, and complications of laser whitening treatment to the patient, and pay attention to correcting the patient's excessive demands in a timely manner.

(2) Instruct patients not to breathe through their mouths during treatment to avoid swallowing debris and whitening agents, and keep the surgical field dry and clear. If you feel any discomfort during the treatment, please raise your hand to signal. Do not talk or turn your head or torso at will to prevent chemical injuries to the oral soft tissue.

2. Postoperative precautions

(1) Treatment of tooth sensitivity: Explain to the patient that tooth development and health care conditions vary from person to person. If the patient has worn or cracked teeth, tooth sensitivity may occur after treatment. If the patient experiences significant discomfort, the patient can take painkillers under the guidance of a doctor. Tooth sensitivity will disappear within 6-24 hours after treatment.

(2) Dietary guidance: It is recommended to eat white or colorless food within 24 hours after laser whitening treatment; try to avoid consuming red wine, cola, coffee and tea, soy sauce, mustard, ketchup, chili sauce, and spicy food that is too cold or too hot; avoid using colored toothpaste and colored mouthwash; avoid smoking. Do not eat hard things, such as olives.

7. Side Effects

1. It is normal for some teeth to feel sore and sensitive during the laser whitening treatment or within a few days after the treatment.

2. Laser whitening uses a safe light source. The light emitted by this light source does not exceed 5oC. There is basically no feeling when the light is irradiated on the skin. After being isolated from ultraviolet rays and far-infrared rays, it will not cause harm to the human body or skin.

3. For teeth with hypoplastic enamel, cracked teeth, and moderate wear, there will be greater discomfort during cold light whitening treatment than normal teeth, but they will recover on their own within 24 hours after the operation.

4. Laser whitening will not cause irreversible damage to teeth and gum soft tissues.
