The teeth are so yellow. Tell me how you all whiten your teeth scientifically.

One-off, non-irritating, non-side effects of cold light tooth whitening technology is the most popular tooth whitening technology in Europe and America. This technology can whiten teeth in 30 minutes by using special cold light irradiation, and the effect can last for more than 2 years. It is suitable for drug-induced discolored teeth caused by exogenous pigment teeth, moderate and mild tetracycline teeth, dental fluorosis, tobacco stains and tea stains.

Second, laser bleaching.

Ion laser activates the catalyst at a specific wavelength, so that bleaching drugs penetrate into the deep layer of teeth and teeth are bleached from the inside out. Its characteristics are rapid, repeatable and basically painless. If the indications are properly selected, the effect can last for more than 10 years. Suitable for moderate and mild tetracycline teeth, dental fluorosis, black and yellow teeth, etc.

Third, photocuring covering.

Using photosensitive curing technology to cover the surface of teeth with porcelain resin is safe and painless, with color selection, repair and redo, which can be completed at one time and maintained stably for more than ten years. It is suitable for patients with severe tetracycline teeth, dental fluorosis, black and yellow teeth and tooth discoloration caused by various enamel dysplasia.

Fourth, porcelain whitening.

This is a method of applying porcelain-fused-to-metal technology to whitening front teeth. Its characteristic is that the shape, color, arrangement and hardness of teeth are natural and perfect, which provides a reliable guarantee for some people who have special requirements for teeth.

Five, drug washing method

It is mainly suitable for teeth yellowing caused by mild pigment teeth, hypoplasia of enamel and changes of enamel with age. The effect on tetracycline teeth and yellow teeth with heavy colors is poor, because only the surface layer turns white and is not durable. At present, there are hydrogen peroxide decoloration and comprehensive decoloration. Generally, the price of such products abroad is about half as expensive as that at home.
