In the case of fluorosis and mild yellow teeth, the patient may not be treated, but cleaned as much as possible. If the aesthetic requirements are very high, the patient can have the teeth bleached, and the bleaching agent can free the pigment from the teeth, and the teeth will become white. If the yellowing of the teeth is serious and the bleaching effect is poor, dental veneers can be done. Nowadays, the technology of veneers is more advanced, using computerized scanning and computerized comparison of the color and luster of the neighboring teeth to design the realistic degree of teeth, so that you can get the perfect design and production. If the yellowing of the teeth is caused by food attachment, the treatment is relatively simple, routine cleaning and periodontal scaling can restore the patient’s white teeth.
