Whiten Your Teeth Without Hurting Them

There are many varieties of teeth whitening products on the market, which are eye-catching gimmicks. However, there are different opinions on the actual effect and how to choose. Many people don't know that orthodontists are also experts in teeth whitening. Because after removing the wire braces, although the teeth are arranged neatly, they may appear uneven in color. In this case, you need to receive a whitening treatment under professional guidance by teeth whitening. If you have noticed children changing teeth, you will find that the permanent teeth that have just grown are often yellow, but they will gradually become white when they grow up.

The color of a tooth is related to its structure. The outermost layer of the tooth is enamel, and underneath is the yellowish dentin. Healthy tooth enamel itself is translucent, so the color of dentin will show through from inside, making the teeth slightly yellowish. Therefore, in most cases, slight yellowing of the newly replaced teeth is normal, indicating a high degree of mineralization, firmness, and corrosion resistance. Over time, the minerals in the enamel will be lost and the transparency will decrease, and it will appear whiter.

Causes of tooth discoloration

In addition to the natural yellowishness, teeth can also become discolored for other reasons. Generally speaking, it can be divided into two types: endogenous and exogenous:

Exogenous: Due to factors such as smoking, drinking tea, or improper oral cleaning, the pigment adheres to the surface of the tooth or infiltrates into the deep layer.

Endogenous: The color of dentin changes due to problems such as drugs and trauma, such as tetracycline teeth.

Professional teeth whitening method

Teeth cleaning are one of the conventional dental care methods, and it has a certain whitening effect at the same time. The high-frequency vibration of the ultrasonic wave can crush the calculus and stains on the tooth surface to achieve the purpose of preventing periodontal diseases. The final step of washing the teeth is polishing, which will further remove dirt and make the surface of the teeth smoother and less susceptible to staining.

The cold light whitening performed in the clinic also uses peroxides, but the concentration is higher, and the blue light is used to catalyze the whitening speed. Under the supervision of a doctor, the gums can be properly and meticulously protected, and safety can be improved significantly. The same principle of tooth whitening can also be done at home.

The doctor will make a personal tray for the patient (similar to an orthodontic holder), and adjust the peroxide concentration according to the specific situation so that the patient can wear it by himself. For teeth with endogenous discoloration or abnormal calcification, and fluorosis, porcelain veneers or all-ceramic crowns may be needed to improve. In orthodontics, this technique is also used for the treatment of small teeth.

Finally, a neat tooth can reduce the difficulty of cleaning, leaving food residues and dental plaque nowhere to hide, helping to maintain health and whitening.
