Introduction
In general, yellow teeth can be whitened using methods such as whitening toothpaste, baking soda brushing, whitening strips, professional dental cleaning, and cold light whitening. Whitening toothpastes typically contain special ingredients such as abrasives, chemical adsorbents, or optical brighteners. It is important to maintain good oral hygiene by rinsing after meals, brushing teeth morning and night, avoiding foods and drinks that easily stain teeth, and replacing toothbrushes regularly.
In general, yellow teeth can be whitened through methods such as whitening toothpaste, baking soda brushing, whitening strips, dental cleaning, and cold light whitening. Specific details are as follows:
1. Whitening Toothpaste
Whitening toothpaste typically contains special ingredients such as abrasives, chemical adsorbents, or optical brighteners. Abrasives help remove surface stains and plaque, making the tooth surface cleaner; chemical adsorbents can bind to pigment molecules on the tooth surface, reducing pigmentation; optical brighteners reflect light, creating a visual effect that makes teeth appear whiter.
2. Baking Soda Brushing
Baking soda has mild abrasive and cleaning properties, gently removing surface debris and pigmentation from teeth. Its alkaline components also help balance the oral pH, inhibit bacterial growth, reduce pigment deposition caused by bacterial metabolism, and gradually whiten teeth.
3. Whitening Strips
Whitening strips usually contain bleaching agents such as hydrogen peroxide or carbamide peroxide. These ingredients penetrate the tooth enamel and initiate oxidation-reduction reactions with pigment molecules, breaking them down into colorless substances, thereby achieving tooth whitening.
4. Dental Cleaning
Ultrasonic cleaning uses a high-frequency vibrating ultrasonic tip to remove tartar, plaque, and surface stains from teeth, restoring their natural cleanliness. Air-polishing cleaning uses a specialized jet device to spray fine particles (such as pearl salt) onto the tooth surface, effectively removing pigmentation, tobacco stains, tea stains, and other discolorations. It also polishes the teeth, leaving them smoother and brighter.
5. Cold Light Whitening
Cold light whitening is a professional teeth-whitening technique. It involves applying a whitening gel to the tooth surface and then illuminating it with high-intensity blue light. Under the catalytic effect of the cold light, active ingredients in the gel—such as hydrogen peroxide—rapidly trigger oxidation-reduction reactions that break down deep-set pigments within the teeth, resulting in quick and effective whitening.
To maintain results, it's important to practice good oral hygiene: rinse after meals, brush teeth morning and night, avoid highly pigmented foods and beverages, and replace your toothbrush regularly.
