A coin has two sides, and it is more common for everything in the world to have two sides and multiple sides. In life, the oral products that everyone will come into contact with more or less, do they have multiple "faces" that you have never known? Let's reveal the "cold knowledge" of these common oral products!

Toothpicks: Toothpicks can both clean and damage your teeth

Toothpicks are a must-have helper for household oral cleaning after meals, but improper use of toothpicks is not uncommon, and there are certain hidden dangers and misunderstandings in the use of toothpicks.

On the one hand, many people continue to use toothpicks after meals as a habit, but picking their teeth indiscriminately without plugging their teeth may cause gingivitis, gingival recession, and enlargement of interdental spaces, which in turn leads to periodontal disease. On the other hand, remember not to force the toothpick into the interdental papilla area, because this will increase the gap between the teeth without a gap and cause periodontal disease.

Toothbrush: The toothbrush is easy to be contaminated with bacteria if it is left in the toilet for a long time!

A toothbrush is an oral cleaning product that everyone can’t live without, but when your toothbrush itself is not clean, isn’t sending it into the mouth just sending the disease into the body? One thing that cannot be ignored in life is that we need to clean our toothbrushes after brushing our teeth. After cleaning, it is not finished. The cleaned toothbrush is easily contaminated by bacteria splashed by the toilet flush, and the wet toilet is not conducive to the drying of the toothbrush.

Toothpaste: The whitening effect of toothpaste is questionable

Toothpaste can indeed help to clean the mouth, and people's pursuit of teeth whitening has led to the emergence of many toothpastes on the market that highlight the effect of "whitening teeth". In fact, the color of the teeth themselves is not pure white.

The "whitening toothpaste" on the market is often added with abrasives or peroxides, and only has a certain effect on mild tooth discoloration. However, it has no effect on those with deep coloration such as tetracycline teeth and fluorosis teeth. If you want to whiten your teeth, you can't rely on a "whitening" toothpaste, improving your eating habits and cleaning your teeth is the right choice.

Flossing: Reusing floss? Absolutely not!

For people with conditions, using dental floss for oral cleaning after meals can effectively promote periodontal health. Looking at the dental floss as if it can be washed and reused? Get the water out of your head now! Trying to reuse dental floss is one of the worst "environmental" hacks.

Dental floss is mostly disposable and not reusable! The dirt and bacteria on the used dental floss cannot be cleaned by ordinary methods (water flushing, etc.), and repeated use of dental floss is harmful but not beneficial.

Mouthwash: Choose your mouthwash carefully

The main function of non-drug mouthwash on the market is to eliminate bad breath, and it is generally suitable for the general population. Medicated mouthwash is mainly used to treat oral inflammations such as gingivitis, periodontitis, oral ulcers, etc. It should be used according to the doctor's advice. In particular, people who are prone to tooth decay or have severe tooth decay, those who wear orthodontic appliances or who have received radiation therapy, need to use fluoride mouthwash under the guidance of a dentist to strengthen the protection of teeth and prevent tooth decay.

Chewing Gum: Chewing gum often can make you sick

There are also many hidden dangers of chewing gum often. First, chewing gum with sufficient sweeteners is easy to induce dental caries. Second, chewing gum may be life-threatening if it accidentally enters the trachea. Third, chewing gum for a long time, the masticatory muscles are always in a tense state, which may cause the masseter muscles to develop and affect the face. Fourth, chewing gum for a long time will reflexively secrete a large amount of gastric acid, which will not only cause nausea, loss of appetite, acid reflux and other symptoms in the fasting state, but may also lead to diseases such as gastric ulcer and gastritis in the long run.
