2. Laser whitening: Using laser to remove tooth discoloration caused by tetracycline and smoke stains left after smoking has a good effect and can whiten teeth with relatively few adverse reactions;
3. Cold light whitening: drugs are infiltrated into the tissues of teeth by cold light to remove pigmentation in the deep and surface layers of teeth, so as to achieve the effect of whitening teeth;
4, drug bleaching: teeth can be bleached with drugs such as hydrogen peroxide;
5. Veneering: Biting discolored teeth with resin or porcelain materials can also make the teeth look white, but some tooth tissues need to be removed, which will cause certain damage to the original teeth.
In addition, eat more crude fiber foods and foods rich in vitamins and calcium, such as fresh fruits and vegetables, milk, shrimp, eggs and so on. Drinking more water, drinking less carbonated drinks and coffee, quitting smoking and developing good brushing habits will all contribute to tooth whitening.
