What are the dangers of teeth bleaching

We must laugh often in our daily life. Only by laughing can we avoid aging. However, when we laugh, we usually show our teeth. If our teeth are very yellow at this time, it will be very embarrassing. So now there is a technology in medical cosmetics called teeth bleaching, which is mainly used for the situation where teeth are yellow. But what kind of harm does teeth bleaching cause to the human body?

1. The harm of teeth bleaching

1. Generally speaking, tooth bleaching is harmless, but too frequent tooth bleaching will definitely affect the health of the teeth and even the oral cavity.

2. Teeth bleaching can be divided into external bleaching and internal bleaching. External bleaching refers to whitening the surface of the teeth and does not have the effect of bleaching the inner layer. Internal bleaching is only performed on dead teeth. This method causes great damage to the teeth, so patients should choose it with caution.

3. If traditional teeth bleaching cannot achieve the requirements of whitening teeth, you can also choose other teeth whitening methods, such as cold light whitening. Cold light whitening may cause side effects of tooth sensitivity to cold and heat, such as tooth acid, tooth decay, and slight decalcification of tooth enamel.

4. Generally speaking, tooth bleaching and subsequent consolidation take several weeks or even months.

2. Teeth bleaching method

1. Tooth polishing: Use some polishing instruments to remove pigments and plaque on the tooth surface, making the tooth surface look smoother and brighter, and can also delay the re-attachment of plaque and pigments. The pigments on the surface of teeth not only affect the aesthetic appearance of the teeth, but also easily accumulate plaque and cause periodontal disease.

2. Teeth cleaning: also known as supragingival scaling, uses a type of scaling instrument to remove tartar, plaque and pigments deposited on the surface of teeth. It should be noted that after periodontal treatment, in addition to daily brushing, regular cleaning is required within six months to a year to completely remove the remaining or new plaque and tartar.

3. Sandblasting: It refers to the use of air and water to spray polishing particles such as sodium bicarbonate onto the surface of teeth through a controllable spray gun to remove tartar and plaque, thereby achieving the effect of whitening teeth.

4. Cold light whitening: It refers to the use of cold light to penetrate the drug into the tooth tissue. This method belongs to chemical bleaching, which is quick to take effect and has a short operation time. The tooth whitening effect can last for more than 2 years.
