Why do teeth turn yellow?

The teeth become yellow or even brown due to stains that are created and spread on the surface of the tooth (enamel) as well as in the lower part of the tooth structure. The white top, or tooth enamel, is hard. Beneath the tooth enamel, there is a pale brown material called dentin. If the enamel thins, dentin is exposed, which is common among adults. Tooth decay results from the chronic deterioration of hard tooth tissue, which has been removed from the surface of the tooth due to acid or chelation, without bacterial intervention. But what is the cause of tooth enamel thinning? Factors such as aging, genetics, and consumption of foods that cause tooth decay or staining are among the causes of tooth enamel thinning. Many unhealthy habits can also increase the risk of gum disease.

Although it is not reasonable to expect our teeth to remain white and bright as we age, we can avoid factors that accelerate tooth discoloration.

Some of the reasons for yellowing or darkening of teeth are:

drinking tea or coffee;

smoking;

Thinning of tooth enamel due to age;

Improper nutrition that includes excessive consumption of processed foods with high acid content such as some types of drinks, chocolate or sometimes some fruits. Even some supplements aggravate the thinning of tooth enamel due to their acid content.

dry mouth (lack of saliva means poor protection of tooth enamel);

Breathing through the mouth and the nasal airways are closed, which reduces saliva and does not allow the mouth and teeth to remain moist;

taking antibiotics;

excessive consumption of fluoride, especially if this habit started in childhood;

Genetic factors.

Some solution for teeth whitening

 Brushing teeth after every meal and drink

One of the ways to whiten teeth is brushing after eating and drinking

The best way to whiten your teeth is to brush your teeth after every time you eat and drink, although it is not always easy! And depending on where you are when eating or drinking (eg at school or at work) it can be difficult.

Avoiding smoking and drinking a lot of coffee and soft drinks, improving oral hygiene and eating right will help prevent yellowing of teeth. If you have a habit of constantly drinking soda, it is better to use a straw. After drinking sweet or acidic drinks, be sure to drink some water. Try to minimize the consumption of soft drinks to avoid its side effects.

Most foods don’t stain teeth, but if you’re a coffee drinker or smoker, you shouldn’t expect your teeth to discolor over time. It is better to do dental scaling at home or at the dentist once every three months and use these home remedies as well.

Foods and fruits

Some foods, such as celery, apples, pears, and carrots, cause the amount of saliva that causes the food to disappear, so after meals when a toothbrush is not available, by eating one of the fruits and vegetables, the teeth are somewhat cleaned.

 Whitening strips with doctor’s prescription:

Teeth whitening strips help to get rid of tooth stains. These strips are very thin and almost invisible and are coated with a peroxide-based whitening gel.
