Why was the Japanese Lion King toothbrush 315 reported? You don’t know much about toothbrush secrets

【Pay attention to the truth-seeking laboratory and learn new knowledge every day】

CCTV 315 Gala will be broadcast on time at 8 o’clock on CCTV-2 CCTV Finance over the years, and its excitement is no less than that of the Spring Festival Gala, which has become the focus of consumer attention, like a commercial black list Oscar awards ceremony, but the winning companies are not happy.

The Truth-seeking Lab also prepared 315 columns to evaluate water purifiers, children’s shower gels and other products, and announce the results next Monday to see which manufacturer is on the black list.

Let’s take a look back at last year’s 315 gala. Through investigation and unannounced interviews, CCTV exposed a number of hidden infringements of consumer rights and interests by enterprises and services. Although many consumers complained about watching a “Buddhist” 315, consumer knowledge science popularization show, etc., the 3·15 party also mercilessly unveiled the other side of a number of enterprises for consumption, such as those that have always been known for quality

Japanese product Lion

It was on the “honor roll”.

Lion King was unfortunately hit

According to the CCTV 3.15 evening, the Liaoning Entry-Exit Inspection and Quarantine Bureau received a complaint that it recently used a Korean brand toothbrush to cause his teeth allergies and teeth bleeding. In this regard, Liaoning Inspection and Quarantine Bureau sampled 20 kinds of Japanese and Korean toothbrushes sold in the Dalian market, and found under the microscope that a large number of imported toothbrushes have sharp angles at the top of the toothbrush wire, burrs are easy to damage oral soft tissues, and do not meet the standards of China’s toothbrush products.

The inspection department took the lead in organizing a special inspection of 100 batches of Japanese and Korean toothbrushes, and the results showed

Probably more than 60% of toothbrushes fail

。 Spot checks found that five toothbrushes, including the Lion ultra-soft care toothbrush in Japan, had unqualified bristles and bristles, Chinese mainland affected a total of 236,000 products. The Japanese Lion King unfortunately became the negative teaching material of this 3·15 party.

Have you picked the bristles seriously?

I don’t know how many consumers choose a toothbrush to pay attention to the softness and hardness of the bristles, whether they pay attention to the material of the toothbrush, the material of the toothbrush bristles is natural bristle and dragon silk.

Natural bristles

The effect and ability to absorb toothpaste are better than nylon silk, but it is more absorbent and dries slowly.

whereas

Nylon wire

Slender and soft, can clean the gap between the teeth, and the elasticity is relatively good, has a good massage effect, coupled with its wear-resistant, non-absorbent characteristics, so it has become the preferred material for bristles.

For the choice of soft, medium and hard bristles, it is generally preferred to be soft or medium, which is flexible and easy to bend, and can effectively remove food debris below the gingival margin and between the teeth. The ends of the bristles are fully rounded to ensure cleaning power and be softer on the teeth and gums, which is less likely to cause damage during brushing.

And the hard bristles because the bristles are too hard, very difficult to use, always feel that the gums hurt, easy to lead to gum recession, tooth neck wedge-shaped, but

For those who deposit tartar, it is still quite useful

。 Therefore, the bristles of the toothbrush are not as fine as possible, just like wearing shoes, toothbrushes should also look for their own toothbrush.

Toothbrush selection is a technical job

The shape of the brush head does not affect the effect of brushing teeth, which is directly omitted here, but the size of the brush head is more directly related to the effect of brushing. The smaller the brush head, the easier it is to clean the lingual side of the back teeth and the mandibular incisors, but this does not mean that the smaller the brush head, the better, and the size of the brush head should also consider the size of the consumer’s mouth.

In general, the length of the brush head of an adult toothbrush should be 2.5~3 cm, the width should be 0.8 to 1 cm, and there are 2~4 rows of bristles, each row of 5~12 bundles of bristles. The length of the brush head of the children’s toothbrush should not exceed 2.8 cm, the width should not exceed 1.1 cm, and the bristles should be 2~3 rows.

Tongue moss is a culture medium for bacteria, which can easily cause bacteria to accumulate and cause halitosis. There are quite a few on the market

The back of the brush head is designed with granules or textures to help clean the tongue

When choosing a toothbrush, the thickness of the brush head is generally not more than 5 mm to prevent excessive action and damage to the gums and internal tissues of the mouth.

In recent years, electric toothbrushes have also become popular, how to choose the best for your teeth? In principle, there are two main categories of electric toothbrushes: rotation and vibration. The principle of rotating toothbrushes is simple, that is, the motor drives the circular brush head to rotate to enhance the friction effect while performing ordinary brushing actions.

Toothbrushes with vibration types are more complex, with an electrically driven vibration motor inside, which allows the brush head to produce high-frequency swings perpendicular to the direction of the brush handle, but the amplitude of the swing is small, generally about 5 mm. When brushing teeth, on the one hand, the high-frequency swinging brush head can efficiently complete the action of cleaning teeth, on the other hand, more than 20,000 vibrations per minute also make the mixture of toothpaste and water in the mouth produce a large number of tiny bubbles, and the pressure generated when the foam bursts can penetrate deep between the teeth to achieve the effect of cleaning dirt.

The choice of toothpaste is even more tangled

Toothbrush is selected, the variety of toothpaste makes people more entangled, the toothpaste sold on the market is generally divided into 7 categories, 1: children’s toothpaste, 2: dodecyl sodium sulfate toothpaste, 3: fluoride toothpaste, 4: fluoride toothpaste, 5, anti-tooth sensitivity toothpaste, 6: whitening toothpaste, 7: natural toothpaste.

In general, children’s teeth are relatively soft, so choose toothpaste without additives, especially do not choose a lot of sweet pigments, especially

Do not contain sodium lauryl sulfate

, this must not contain, this contains mild toxicity, once swallowed by a child will cause chronic poisoning.

Fluoride toothpaste is preferred

, fluoride toothpaste has anti-caries effect, if your teeth are sore, if it is to rule out other reasons, just tooth allergies, you can choose this specific anti-allergic toothpaste.

For whitening toothpaste, don’t expect whitening toothpaste to whiten your teeth, this is unlikely, just like applying a layer of makeup to the face, it may have a brightening effect, but it will not play a whitening effect. There are also natural toothpastes, and generally natural ingredients are also good.

Finally, I remind consumers that before brushing their teeth,

Do not dip the toothbrush in water

, because more foam will affect the friction between the cleaning ingredients in the toothpaste and the teeth. And after we brush our teeth with toothpaste,

Gargling is important

, gargle several times, be sure to thoroughly clean the mouth to prevent residue from causing harm to the body.

In addition, whether it is an electric toothbrush and an ordinary toothbrush, toothbrushes have a service life, it is generally believed that it is more appropriate to change the toothbrush once in up to 3 months, even if the bristles are not broken, they have accumulated a lot of bacteria, or replace it according to the intelligent prompts of the electric toothbrush.
