If your teeth are not as white as you want, then you need to take a good look at this article!

 It is estimated that many people are looking for their teeth to be as white as the models in toothpaste advertisements. There are endless whitening toothpastes, whitening strips, tooth cleaning and tooth whitening that can only be operated by hospitals. Which one is effective?

1. Exogenous factors

That is, the color of the infection on the outside of the tooth.

◎ Foods with pigments in the daily diet. Such as: tooth coloration caused by cola, soy sauce, etc.

◎ Smoke stains caused by smoking;

◎ Drugs, such as chlorhexidine bactericides, polyvalent metal salts, these substances are attached to the tooth surface and appear black and brown.

2. Endogenous factors

◎ Genetic factors

For example, enamel and dentin are affected by developmental factors, and teeth will also appear brown;

◎ Dental fluorosis

The pigment is in the enamel on the surface of the teeth, in the form of yellow-brown plaques, and in severe cases, there are uneven defects on the surface of the teeth;

◎ Tetracycline Teeth

Tetracycline molecules combine with calcium in the tooth tissue to form a very stable complex, which is deposited in the tooth tissue, making the inner layer of the tooth stained yellow, and the tooth is brown-gray or brown-yellow.

◎ Oral treatment

For example, in patients with root canal treatment, the teeth will turn gray and black after a long time because the treated teeth have no pulp.

◎ Age factor

As you age, your teeth wear out slowly, so you can also experience yellowing and blackening of your teeth.

The Secret of Teeth Whitening

1. Whitening toothpaste or whitening strips?

◎ Whitening toothpaste

The principle of use of whitening toothpaste is similar to that of scaling and polishing. It removes unstable pigments on the surface of teeth through chemical adsorption and physical friction.

However, the friction particles in some whitening toothpastes are relatively large, and long-term use will damage the enamel on the surface of the teeth, thereby causing sensitivity, and it is not recommended to use;

◎ Whitening strips

Tooth strips need to be adhered to to be effective. If you stick them only once, the effect is not very obvious. It is recommended to consult a professional dentist before use.

2. Is DIY teeth whitening feasible?

Very not recommended!

Whether you use lemon, white vinegar or other so-called "secret recipes", there are unsafe factors, which are easy to cause damage to the teeth, especially the substances containing acids are easy to demineralize the teeth, damage the enamel, and cause irreversible damage.

3. Can scaling and polishing whiten teeth?

No, simply say "scaling ≠ whitening", the main purpose of scaling is to remove plaque, calculus, prevent periodontal disease, maintain oral health, and cannot achieve the effect of whitening.

Choose a professional dental institution

Teeth whitening can be divided into office whitening and home whitening

1. In-office whitening

◎ Before treatment

Professional dentists will analyze the cause of tooth discoloration through a comprehensive oral examination, customize a personal plan, and estimate the effect of whitening treatment.

◎ under treatment

Correct and standardized operation will not only improve the aesthetic effect of teeth, but also ensure the safety of teeth and gums.

1. Consolidation therapy

Whitening treatments can be repeated at 1-2 year intervals, depending on the individual's oral hygiene and dietary habits.

2. Conventional treatment

◎ Maintain healthy oral hygiene and eating habits;

◎ Avoid taking food, drugs or other pigmented substances that stain teeth;

◎ Regularly perform auxiliary maintenance such as scaling and polishing.
