The Five Whys of Teeth

Why do teeth turn yellow?

Why are some people's teeth as white as jade, while others' teeth are yellow? In fact, don't worry too much, this is normal, because healthy teeth should be ivory color with translucent luster, compared with snow white, it is slightly yellowish, which is the performance of strong teeth.

And those embarrassing yellow teeth have two main causes. Some teeth are not yellow in themselves, but because they do not pay attention to oral hygiene, they have to wear an ugly yellow coat under the action of external factors.

For example, drinking tea, coffee or smoking for a long time will leave tea stains and smoke stains on the surface of the teeth, and the plaque that stays on the tooth surface and between the teeth for a long time will also be mineralized into dental calculus under the action of saliva.

The yellowing of teeth caused by these external factors is not terrible. As long as you pay attention to oral hygiene, adhere to the correct brushing method every day, and go to the dentist for a professional cleaning every three months to six months, these situations can be avoided.

Another type of tooth yellowing is when the teeth are affected during their "development". Vitamin A, C, D, calcium, phosphorus deficiency, severe indigestion, pregnant mothers or children under 8 years old who take tetracyclines will cause tooth coloration, and then gradually change from yellow to tan or dark grey. However, these teeth that have been affected by development and become yellow can also be made beautiful by bleaching or making veneers, crowns, etc.

Why is it bad to pick your teeth with a toothpick after a meal?

Many people like to pick their teeth with a toothpick after eating. Is it good to do this? First of all, we need to know that food impaction is very harmful to teeth. Residual food residues can irritate the gums, and if the impaction lasts for a long time, it can also cause inflammation of the periodontal tissue.

Picking teeth with a toothpick can prevent them from damaging the teeth, but toothpicks often cause damage to tooth tissue.

Because the toothpicks we use are made of wood, although some surfaces have been polished, if we observe through a magnifying glass, we can see that there are rough protrusions on the surface of the toothpick. Using this toothpick to remove food residues is easy to damage the gums and cause bleeding gums. , Inflammation, for this we can use dental floss.

Why can I still get tooth decay without eating sugar?

Generally speaking, sugar refers to sucrose, which is the favorite food of caries-causing bacteria. With it, bacteria will grow more, grow faster, and are prone to tooth decay. Some other foods such as starch are also used by bacteria.

This starch is starch in a broad sense. The pasta, rice, corn, potatoes, sweet potatoes and soybeans we eat every day are all foods with starch as the main component. Due to the lack of cleaning after eating, they are left in the mouth, especially in the gaps between the teeth, and are used by bacteria, resulting in an increase in bacteria and disease. Therefore, you can get tooth decay without eating sucrose.

So how to eat sugar reasonably? There is no need to worry about adding sugar to grains, vegetables, fish, meat, and eggs in three meals a day, but you should control the frequency of sweets and snacks between normal meals. Rinse your mouth after eating sugar. Get rid of the bad habit of eating candy before going to bed or sleeping with candy in your mouth.

Why don't you pull out your teeth easily?

   Don't take out your first tooth lightly. Because people's teeth are sorted and have their own sockets, if one is pulled out, if the tooth is not immediately installed, the side teeth will be crooked.

Experts believe that to hold this level, it should also be reflected in the education of future dentists. Some doctors have misunderstandings in understanding and operation. If the dental disease has reached the level that cannot be treated by the current medical level, the tooth can be extracted, but it must be installed in time.

Baby teeth need to be replaced, why do they need to be filled?

Baby teeth are to be replaced by permanent teeth, should they still be filled? I would like to answer affirmatively: must make up! This is mainly considered from several aspects. First, baby teeth are an important part of the chewing organ in a child's digestive system. Intact deciduous teeth allow better chewing of food, aid in digestion, and benefit your child's growth and development.

At the same time, it can also promote the normal development of the maxillofacial region. Of course, baby teeth also help children with correct pronunciation. Premature loss or loss of deciduous teeth, especially front teeth, will bring psychological harm to children.

In addition, the presence of deciduous teeth can also play a guiding role in the normal eruption of permanent teeth. Defective or premature loss of deciduous teeth can often cause the eruption position of the permanent teeth to be insufficient and misplaced, resulting in irregular arrangement of the permanent teeth. Apical inflammation caused by dental caries in deciduous teeth will also affect the development of subsequent permanent teeth.
