Only two of the seven methods for whitening teeth are right.

There is a saying called “one white covers all ugliness”. Although it mainly refers to white skin, it seems that this sentence is also valid for teeth.

A good-looking person shows his white and neat teeth when he smiles. Is it especially beautiful?

How should tooth whitening be done?

Are the mysterious [folk remedies] circulated among friends that can whiten teeth reliable?

Ding Dang invited a professional stomatologist to tell everyone that these methods are really effective and are just erroneous.

Vinegar or lemon juice?

It doesn’t work, it’s harmful!

Don’t you feel sour?

Perhaps someone was inspired by [white vinegar can remove scale] and felt that white vinegar is acidic and can dissolve scale, so it should be able to remove [tartar]. Anyway, the composition is similar.

Indeed, very sour vinegar or lemon juice can remove tartar.

However, this is a method of [killing 100 enemies and damaging 1,000 oneself]!

The outermost enamel layer of teeth is the hardest structure of the human body. It is characterized by pressure resistance and wear resistance, but it is the least acid resistant.

Vinegar or lemon juice will not only not whiten teeth, but also cause serious injuries to teeth, and these injuries are irreversible.

Rub your teeth with peanut crumbs, salt, orange peel powder, etc.?

It’s useless, it will hurt innocent people!

Won’t it hurt?

The purpose of these methods is to increase friction and hope to remove pigment from the tooth surface.

But in fact, the combination of pigment and tooth surface is very close, and these materials are difficult to remove pigment.

On the contrary, incorrect pressure application will hurt gums and may lead to oral ulcers.

Tooth washing, tooth cleaning and polishing?

This is good for tooth health, but the whitening effect is average.

The main purpose of tooth washing is to remove stains deposited on the teeth, just like bathing the teeth, which will indeed whiten the teeth.

Moreover, routine polishing is required after tooth washing, and very fine polishing particles are used to polish the tooth surface to further remove finer stains.

As a result, the tooth surface will become smoother, thus becoming shiny and brighter.

Although tooth washing is very important to maintain the health of teeth and gums, its effect on tooth whitening is relatively small. We recommend washing teeth once every six months to once a year, but we cannot expect to whiten teeth by washing teeth.

Whitening toothpaste?

A fleeting whitening effect.

Many toothpastes claim to [brighten the color of teeth in two months]. A closer look at the composition list of toothpastes shows that there are indeed ingredients that can play a bleaching role and polishing particles. It seems that they can whiten and polish.

But in fact, bleaching agent needs to reach a certain concentration and time to play its role.

When brushing teeth, the concentration of bleach is diluted very low and has basically no bleaching effect.

However, the short contact between polishing particles and the tooth surface cannot exert the polishing effect.

The coloring particles in whitening toothpaste can indeed stay on the teeth for a short time and slightly improve the original color of the teeth to achieve a short whitening effect.

However, the effect is not lasting, and after the use is stopped, the so-called “bright white” will gradually disappear.

Whitening Tooth Paste?

It is a little reliable, but the maintenance time is short.

The whitening tooth patch contains low concentration of peroxide. As long as the tooth patch can be contacted with teeth for enough time during use, the extremely superficial pigment on the tooth surface can be removed through bleaching.

For example, it is produced by drinking coffee and red wine.

However, whitening tooth patches have no effect on deeper pigments that have entered the teeth.

In order to further improve the color of teeth, a higher concentration of bleach is needed, which requires the participation of dentists, which is as follows:

Cold light whitening

It’s reliable.

In cold light whitening, it is not [cold light] that really plays a whitening role, but bleach.

Chemical reaction can remove the deeper pigment of teeth, and because there is no damage to the structure of teeth, it can be regarded as the non-invasive method with the best whitening effect.

Natural teeth are yellow, acquired pigmentation, mild dental fluorosis, etc. can be used.

Bleaching agent is very safe to act on teeth, but bleaching agent has great stimulation to soft tissues such as gums and lips.

Before bleaching, doctors will apply protective agents to these places to isolate soft tissues.

Cold light whitening requires a qualified dentist to operate. If you want to DIY yourself at home, you should be cautious. If you are not careful, it is likely to lead to oral ulcer, gingival recession and other problems.

Porcelain veneer, all-porcelain crown, porcelain crown?

It’s reliable.

If the color of the teeth is darker, such as tetracycline teeth and moderate to severe dental fluorosis, which cannot be improved by non-invasive methods such as tooth bleaching, then minimally invasive porcelain veneer can be selected.

Porcelain veneer is a bit like [beautiful pupil] lens, which is pasted on teeth through a thin layer to improve the color of teeth and achieve a very natural effect.

When making porcelain veneer, it may be necessary to grind off a small amount of teeth, about 0.3 ~ 0.8 mm. The porcelain veneer technology is very mature, which can ensure that the porcelain has sufficient strength and the adhesion to the tooth surface is very firm.

Porcelain veneer can choose color, as white as you want. The whitest color is called [Hollywood White]. Just like a star, when smiling, your lips are red and your teeth are white. However, it is unnatural and fake to consider that yellow people’s teeth are too white. Therefore, you need to communicate well with doctors.

If the tooth color is too dark or there is a large defect, full crown repair should be considered.

According to the different materials, it can be divided into all-ceramic crown and porcelain crown.

All-ceramic crowns do not contain metal, which can completely simulate the permeability of teeth, while porcelain crowns have metal structures inside, and the color is relatively less transparent. In addition, the amount of teeth to be ground out is larger when making full crowns, and the choice of full crown restoration should also be more cautious.

Of course, there are still many reliable and unreliable methods of whitening teeth, and new technologies are constantly emerging. It is really a bit difficult to distinguish whether various methods are reliable or not entirely by oneself. If you are not careful, you may be brutally attacked by black hands, causing damage to teeth, and it is even more difficult to recover.

Therefore, it is the most reassuring choice to find a reliable dentist and listen to the doctor’s advice.
