Causes of Yellow Teeth
Yellow teeth can generally be divided into two categories: intrinsic and extrinsic.
Endogenous: Refers to internal causes, such as tetracycline-stained teeth and fluorosis.
Tetracycline-stained teeth—are primarily caused by excessive intake of tetracycline-class drugs during tooth development, resulting in abnormal discoloration of the teeth. Fluorosis, on the other hand, is caused by long-term consumption of drinking water with excessively high fluoride levels.
Exogenous: This is primarily caused by long-term habits such as drinking tea and coffee and smoking, where sticky substances on the tooth surface gradually absorb various minerals—such as tea stains and coffee stains—causing the teeth to yellow.
Here are a few skin-whitening methods
Teeth-Whitening Toothpaste
One of the most routine ways to whiten your teeth—after all, you brush every day.
The main mechanism of action is as follows: by adding abrasive agents such as hydrated silica, friction against the teeth is increased, thereby cleaning the tooth surface.
The entire process doesn't affect dental health and doesn't cause any unnecessary sensitivity. Although the results aren't immediate, if you only have a tiny bit of extrinsic tooth discoloration, this is more than enough.
However, brushing your teeth does not fundamentally solve the problem of yellow teeth.
Teeth Whitening Strips
Teeth-whitening strips work primarily because they contain hydrogen peroxide, which uses a redox reaction to break down large organic staining molecules (dark-colored) on the tooth surface into smaller molecules (light-colored).
However, they can be quite irritating to the oral environment, and users may experience tooth sensitivity or pain during use. Since the strips need to be worn consistently to be effective, a single episode of sensitivity is far from enough. Although most products are safe, the user experience is really quite poor.
Redox = Hydrogen Peroxide * High Irritation * Poor User Experience
Teeth Cleaning
Known by its technical term as “supragingival scaling,” commonly referred to as “teeth cleaning,” this is a simple yet vigorous physical cleaning method that typically costs between 100 and 500 yuan.
In fact, its primary function is cleaning. The so-called “whiter” appearance is simply the result of ultrasonic technology removing tartar, plaque, and surface stains, making the teeth look whiter—but the deep-seated stains are still there.
For example, if you already keep your teeth clean on a regular basis, this method won’t do much to whiten them. However, people who regularly drink tea or coffee, or who smoke, might want to give it a try.
Teeth Cleaning = Ultrasonic * Cleaning * Simple and Rough
Cold Light Teeth Whitening
This is arguably the safest and most effective teeth whitening method available today. It works by using cold light to penetrate the whitening agent deep into the teeth to achieve the whitening effect; it is a form of chemical whitening. The results are proportional to the cost—it is relatively expensive, ranging from approximately 1,500 to 5,000 yuan. However, those interested in this method should take note: it is essential to have the procedure performed at a licensed dental clinic. When performed properly, it causes minimal damage to the teeth, and the hardness of the enamel and the dental nerves are generally unaffected.
This method can be somewhat irritating and is not suitable for people under 16 or those with existing dental damage.
Cold Light Teeth Whitening = Chemical Teeth Whitening * Irritating * Expensive
Dental Veneers
A quick and long-lasting way to whiten teeth—but getting a full set of teeth done costs at least tens of thousands of yuan. The procedure involves grinding away the outer layer of the teeth and then applying artificial veneers. These days, most actors opt for this method to achieve a flawless appearance on camera, but it actually causes significant damage to their teeth.
Take Liu Tao, for example: when her porcelain crown fell off, it was clear that her natural teeth had been almost completely ground down. After the procedure, it was as if she had put a mask over her entire set of teeth.
So, unless it's absolutely necessary, there's no need to do it.
Dental Veneers = Grinding the Outer Layer of the Tooth * Artificial Veneer * Damage
