Can teeth whitening be achieved by teeth cleaning? Get to know these teeth whitening misunderstandings and say goodbye to "yellow teeth"

It is very important for everyone to have healthy teeth. With the improvement of hygiene awareness, people have higher and higher requirements for the beauty of teeth. Many people have begun to try various "whitening" methods, hoping to show their smile more confidently when socializing.

Why do teeth turn yellow? What is teeth whitening? What are the methods? This article provides detailed information.

Causes of abnormal tooth discoloration

The visible crown part of the tooth in the mouth is composed of enamel, dentin and pulp. The normal tooth color comes from the dentin, which is slightly yellow. The outermost enamel is translucent, so normal teeth are slightly yellow.

The higher the mineralization of tooth enamel, the more transparent it is, and the more the "yellow" of dentin is prominent. The mineralization of deciduous teeth is often lower than that of adult permanent teeth, so children's deciduous teeth look whiter.

Doctors say that there are two main reasons for abnormal tooth discoloration:

Intrinsic coloration

Endogenous staining is caused by internal factors of the teeth themselves, such as abnormalities in the tooth development process, which can lead to tetracycline teeth, fluorosis, etc.; tooth discoloration caused by pulp degeneration and invitamin; tooth discoloration caused by systemic diseases, etc.

Exogenous pigmentation

Exogenous staining is tooth discoloration caused by external factors, such as drinking tea, coffee, cola or smoking for a long time. These pigments will accumulate on the surface of the teeth, forming "dirt" and discoloring the teeth.

What is teeth whitening?

Teeth whitening is a cosmetic dental treatment that removes pigment deposits from the surface of teeth to make them whiter and more beautiful, using devices such as bleaching agents or light therapy.

Office whitening is one of the most common and effective methods of teeth whitening. Dentists use bleaching agents or light therapy equipment for professional whitening. Doctors can also achieve whitening effects by treating pigmentation deposits inside the teeth. The advantages of this method are long-lasting effects and low rebound, but the disadvantage is that it requires a more complicated treatment process.

Patients can also use bleaching agents or teeth whitening strips at home for simple whitening. Compared with office whitening, home whitening is cheaper and more convenient, but the effect is slower.

Doctors remind that no matter which teeth whitening method is used, you need to pay attention to the following points:

▲Before whitening treatment, a comprehensive oral examination should be conducted to determine whether whitening treatment is suitable.

▲During whitening treatment, you should follow the dentist's advice and guidance and use whitening agents or equipment correctly to avoid damaging your teeth.

▲After the whitening treatment, you should pay attention to your oral hygiene habits and avoid eating foods with high pigments to prolong the duration of the whitening effect.

Common teeth whitening misconceptions

Many people have many doubts about teeth whitening. Experts have given the following answers:

Can teeth cleaning whiten teeth?

Teeth cleaning cannot whiten teeth. If you do not brush your teeth thoroughly for a long time, dental plaque will accumulate and mineralize, forming tartar. The main purpose of teeth cleaning is to remove tartar and maintain periodontal health.

Can teeth whitening be achieved using a teeth whitening device?

Teeth whitening devices are not suitable for everyone. When used by people who lack oral knowledge, they are likely to damage soft tissues such as gums. Therefore, it is not recommended for everyone to use them.

Can you whiten your teeth by using tooth powder or whitening toothpaste?

Products such as tooth powder and whitening toothpaste are easy to use, and many people choose to try them, but these products can only play a basic cleaning role and have no whitening effect. Tooth powder can "polish" teeth for a long time, which will also damage the enamel layer of teeth and affect dental health.

Does tooth discoloration affect oral health?

Tooth discoloration itself does not necessarily have a direct impact on oral health, but it may indicate some oral health problems, such as poor oral hygiene, caries lesions or oral infections.

How long do the effects of teeth whitening last?

The effects of tooth whitening can last from several months to several years, depending on the patient's lifestyle and oral hygiene. If you often eat foods with high pigmentation, such as coffee, red wine, tea, etc., or do not pay attention to oral hygiene, the whitening effect may be shorter.

Are there risks with teeth whitening?

Teeth whitening is a relatively safe treatment method, but there are still certain risks when using whitening agents, light sources and other equipment. For example, hydrogen peroxide, too high a light source or excessive treatment may cause irritation and damage to teeth and gum tissue.

Can bleaching agents whiten all teeth?

Different teeth have different colors and structures, so bleaching agents are not suitable for all teeth. For example, the bleaching effect may be poor for teeth with heavy gray or yellow tints. In addition, if the teeth have problems such as caries or root canal treatment, bleaching treatment is not suitable.

Is it better to have stronger bleach?

Excessive use of bleaching agents or using too concentrated bleaching agents may damage and irritate the teeth, causing tooth sensitivity, pain and other problems. Therefore, it is recommended that patients follow the advice and guidance of their dentists when undergoing bleaching treatments and not overuse bleaching agents.

The right way to whiten teeth

In the past, the commonly used whitening technology was cold light whitening. In recent years, a new type of whitening has emerged. It breaks the limitations of traditional cold light whitening by combining hydrogen peroxide, potassium nitrate and fluoride, and overcomes the dilemma of tooth soreness during traditional cold light whitening and gum allergy after whitening.

The new type of whitening system provides simultaneous dental care, whitens teeth comfortably and protects teeth scientifically. It significantly improves the pain caused by traditional teeth cleaning, reduces the time required for teeth beautification by half, and has a unique teeth whitening formula to maintain the whitening effect.

How to take care of your teeth properly

To keep your teeth healthy, you first need to maintain good oral hygiene habits. It is recommended to brush your teeth twice a day, brushing for more than two minutes each time, and use fluoride toothpaste to effectively remove plaque and pigment deposition on the surface of the teeth and prevent the occurrence of caries and oral diseases.

Secondly, diet also has a great impact on dental health. Doctors recommend that you eat less sugary or acidic foods, such as candy, carbonated drinks, lemon juice, etc. At the same time, eating more foods rich in calcium and vitamins, such as milk, cheese, green vegetables, etc., can effectively protect dental health.

In addition, you also need to pay attention to some bad oral habits, such as smoking, excessive coffee drinking, etc., which will cause damage to the teeth and form pigment deposits, thus affecting the beauty and health of the teeth.

Doctors remind that healthy teeth are not necessarily whiter. Before teeth whitening, you should seek guidance and advice from professional doctors and not blindly follow the trend. If you find any abnormalities in your teeth, such as toothache, bleeding gums, tooth sensitivity, etc., you need to go to the hospital for diagnosis and treatment.
