According to etiquette experts, teeth are a woman’s calling card. If you have straight, white teeth and fresh breath, you must be a well-educated lady.
But if your teeth are yellowish, people will think less of you!
Experts say that some people’s teeth are not yellow is sick, the teeth are cut open, there are three layers of longitudinal tissue, the most outside is tooth enamel, varies from person to person, slightly different, because the calcification degree of each person’s teeth is different, some people’s teeth are milky white, some people are light yellow, this is healthy.
There are many people’s yellow teeth are sick, generally due to: 1, health factors: teeth in the process of development due to poor nutrition or disease, will make the teeth of the calcification affected, teeth will be yellow and brittle.
2. Water quality factors: in some areas, especially in some mountainous areas, due to the high fluoride content in the water, excessive drinking fluoride teeth will turn yellow, and not 1-2 teeth, but a mouth of rhubarb teeth.
Fluoride has the effect of preventing caries, so these people are not susceptible to caries (tooth decay).
3, drug factors: Now most people know that tetracycline drugs can cause the occurrence of yellow teeth, especially in children (before the age of 5) take the impact is greater.
4, health habits: some people do not pay attention to oral hygiene, morning and evening brushing habits, the surface of the teeth accumulation of a layer of food residue, soft scale, calculus, smoke stains, tea stains, etc.
These “yellow teeth” are not yellow teeth themselves, but are caused by poor oral hygiene.
Specifically, the reason for tooth yellowing mainly has the following eight points: 1, calcium deficiency teeth are also an important part of bone composition!
When calcium is lost from the body, teeth become much less rigid and more absorbent to food, resulting in pigmentation and yellowing.
Therefore, it is recommended that you take regular calcium tablets and vitamin D to help your body synthesize high-quality calcium.
And don’t forget, going out in the sun can also help your teeth absorb more calcium!
2, drinking mineral water fluoride on the one hand can increase tooth enamel, make it stronger, on the other hand will make teeth gradually yellow.
Mineral water contains a lot of fluorine elements, drink too much, will let your white teeth pale!
American oral health experts suggest that everyone drink at least 1000 milliliters of white water every day, including mineral water intake should not exceed 300 milliliters, remaining 700 milliliters, can drink pure water or boiled tap water.
3, toothbrush is too hard in terms of cleaning effect, hard bristled toothbrush is much better than soft bristled toothbrush.
But the abrasion effect of hard bristle toothbrush on teeth is larger, often use can damage tooth surface enamel, make pigmentation.
People who often use a hard toothbrush, even if the teeth are hard, the color will not be too white!
Therefore, it is recommended that you prepare two hard and soft toothbrushes and use a hard bristled toothbrush every 3 days to thoroughly clean the tartar.
But don’t use a hard-bristled toothbrush during your menstrual period!
Because the body’s metabolic level is unstable, the enamel is more vulnerable to damage!
4. Drinking black tea or black tea tea contains a large number of polyphenolic oxides. Long-term tea drinking will make your teeth yellow.
The study found that black tea has the highest amount of polyphenol oxide, followed by black tea, Pu-erh tea and barley tea have the lowest amount of polyphenol oxide, so you can drink it safely!
In addition, the longer the tea time, the lower the effect of the oxide, in order to ensure that you have a white teeth, you can appropriately extend the tea time!
5, drink Cola Coca-Cola composition is syrup and carbon dioxide gas, drink too much, will make sugar calm in the tooth surface, make its color black.
A study found that if you drink one litre of cola a day, half of the enamel on your teeth will be eaten away by acid after two years.
Among carbonated drinks, dark colas are the most damaging to teeth, followed by orange soda. Generally speaking, the lighter the drink, the safer it is. It is recommended that you choose clear Sprite!
6, cleaning too often WHO (the World Health Organization) dental experts believe that as long as usually pay attention to tooth cleaning, the average person once a year is enough, if you often smoke, that needs to wash 2-3 times a year.
Experts point out that too much cleaning can make the gap between the teeth enlarged, the teeth are allergic, food residue and color easily attached to the tooth surface.
7. Eat Curry Turmeric, the main ingredient in curry, has overtaken nicotine as the number-one influence on tooth color, according to the American Dental Association’s latest “tooth staining” list.
Turmeric has an almost irreversible staining effect on teeth, making it a veritable ‘white tooth killer’, according to the study.
If you really like the spiciness, I suggest you choose green curries with the weakest staining force and avoid red and yellow curries with the strongest staining force!
8, drug toothpaste as the saying goes “is medicine three points poison”, drug toothpaste can control the production of pathogenic bacteria, but also destroy the “ecological balance” in the mouth, cause new infections.
What’s more, alkaloids in medicated toothpastes can damage the enamel on the surface of teeth and make them lose their luster!
