What to do if the inside of teeth is yellow

Neat teeth make a great impression and indicate that our oral cavity is in good condition. However, some people's teeth appear yellow inside. Even if they usually pay attention to cleaning their teeth, this problem may still occur. They must be concerned about the solution. The reasons for yellow teeth are different, and the solutions are different. So, what should you do if your teeth are yellow inside? Let’s look at the solution below.

1. Developmental factors

During the development of teeth, due to malnutrition, infectious diseases, high fever, and serious illness, the enamel of the teeth will be underdeveloped and calcification will be affected, and the teeth will become yellow and brittle. In this case, the enamel of the teeth will lose its luster and become opaque, and may be yellowish-brown. In severe cases, the surface of the teeth may be rough and spotted, with incomplete appearance and often symmetrical on the left and right. Dental nutritional disorders caused by developmental factors lead to poor calcification, which reflects the impact of past health conditions on the teeth. It is meaningless to supplement calcium and vitamin D after birth.

2. Drug factors

This is the "tetracycline teeth" that most of us know. Tetracycline drugs can cause yellow teeth. Tetracycline drugs were widely used in the 1960s and 1970s. Excessive use of this type of drug can accumulate in the tooth tissue, staining the inner layer of the teeth yellow. Taking too much tetracycline during the tooth calcification period (deciduous teeth during the mother's pregnancy, permanent teeth before the child is seven years old) can easily lead to tetracycline teeth. Children usually have to wait until the age of 7 to change their teeth before yellow teeth appear.

3. Hygiene factors

If you do not pay attention to oral hygiene and do not develop good brushing habits, a layer of food residues, soft plaque, tartar, smoke stains, red wine, rice wine, tea stains, coffee, and Chinese medicine will accumulate on the surface of your teeth. The yellowing of teeth in these cases is not due to the teeth themselves turning yellow, but is caused by not paying attention to oral hygiene. It only affects the surface color of the teeth and is relatively easy to remove.

4. Water quality factors

In some areas, especially mountainous areas, the fluoride content in the water is high. Drinking this kind of fluoride-containing water will cause the teeth to turn yellow, involving all the teeth in the mouth. Fluoride has the effect of preventing tooth decay. This kind of teeth are not prone to tooth decay. We call it "dental fluorosis" or "dental fluorosis". It is caused by excessive intake of fluoride by the human body during the calcification period of tooth development. Excessive fluoride content in natural water can easily lead to dental fluorosis, which is a manifestation of endemic fluoride poisoning.

2. Treatment of yellow teeth

Depending on the depth and cause of yellowing of teeth, different methods such as teeth cleaning, whitening toothpaste, teeth bleaching, whitening teeth stickers and porcelain restoration should be used for whitening. No matter which method of teeth whitening is used, it must be ensured that caries and periodontal disease have been treated and the teeth are healthy. Otherwise, dental diseases will be aggravated.

1. Whitening teeth stickers

The latest and most popular teeth whitening method is convenient, fast, simple and cheap. It has been popularized in foreign countries for a long time. The clinical effect is still quite obvious and it has a tendency to gradually replace bleaching. However, whitening teeth strips are not suitable for teeth with discolored dentin due to tetracycline, fluorosis, etc.

2. Cold light whitening technology

The bleaching agent covering the tooth surface is irradiated with a special cold light source, allowing it to penetrate into the hard tissue of the tooth in a short period of time to achieve the purpose of changing the color of the teeth. Its advantage is that it does not damage the hard tissue of the tooth and the operation treatment time is about 30 to 45 minutes. However, the disadvantage is that due to the bleaching effect of the drug, the bleaching effect varies from person to person.

3. Teeth cleaning

Many people think that teeth cleaning is a cosmetic whitening of teeth. In fact, the main function of teeth cleaning is not whitening, but a routine dental care method. It is a routine health care method that mainly prevents caries, gums, and periodontal diseases, targeting tartar and plaque on the surface of teeth. Cleaning your teeth through regular teeth cleaning once every six months is a good habit to maintain dental health. Although the purpose of teeth cleaning is not to whiten teeth, teeth will naturally look whiter after cleaning.

4. Whitening toothpaste

Basically, it does not have much whitening effect. It is mainly through physical friction between the abrasive and the stains on the surface of the teeth. Some whitening toothpastes also contain oxidants, but due to the small content of chemical ingredients, the general short brushing time, and the easy loss of effectiveness after being left for a long time, the whitening effect is very small. If the original color of the teeth is not too dark or yellow, using whitening toothpaste can still have a certain maintaining and promoting effect; however, if there are obvious stains, smoke stains, wine stains, tea stains, coffee, Chinese medicine and other pigments on the surface of the teeth, using whitening toothpaste will have no effect at all.

5. Teeth bleaching

Suitable for moderate to mildly discolored teeth, this bleaching beauty method is applicable to a wide range of people and ranges, and can be used by people over 18 years old. However, it is difficult to achieve good whitening effects using ordinary bleaching methods for teeth with discolored dentin due to tetracycline, fluorosis, etc. Bleaching is done by taking a mold of the tooth shape and making a pair of dental trays. The bleaching agent is placed in the dental trays and worn on the teeth before going to bed every night. The ingredient of bleach is 30% hydrogen peroxide, which will produce a reduction reaction with the melanin on the teeth, restoring the teeth to their original color. The risk is small, the effect is quick, and there is no damage to the gums and pulp. The treatment course is generally about one month, and the longest cannot exceed 3 months. Some people will feel toothache during the bleaching process and be sensitive to cold and heat. This is a normal reaction and will return to normal after the treatment is completed. The effect of teeth bleaching is different for each person. In order to achieve the best whitening effect, you can bleach it repeatedly several times, but no more than three courses of treatment, otherwise it will cause certain damage to the teeth.

6. Restorative treatment

Porcelain veneers or porcelain tooth restoration methods are an ideal way to beautify cracked and defective teeth. It should be noted that if you grind down your normal teeth just for whitening and then put on porcelain braces, this will not be worth the effort and will have a certain impact on the teeth themselves, because the restorative treatment method requires grinding off a portion of the natural teeth and covering the corresponding parts of the teeth with artificial porcelain veneers or porcelain teeth. The advantage is that the color of the teeth changes significantly, but the disadvantage is that a portion of the natural teeth must be ground off, and complications may also occur due to teeth grinding stimulating the pulp.
