White teeth can make a smile shine, and with today’s ever-evolving technology, there are many techniques that can help people make their teeth whiter. But did you know? Teeth whitening is also a misunderstanding. Myth 1, any “teeth” can be whitened Teeth whitening agent is only effective on natural teeth, will not change the restorations (such as composite resin fillings, porcelain teeth) their own color. For different reasons of tooth staining or discoloration, there will be individual differences in the level of whitening that can be achieved. If the teeth are whitened before porcelain veneers or all-porcelain crowns are restored, the color of the affected and neighboring teeth can be improved, making the final restoration more lifelike and brighter. Myth 2, the whitening effect of all people is the same The color of each person’s teeth is different, and its whitening effect is intimately related to the cause of tooth staining or discoloration, the mineralization of the teeth, the individual’s diet and oral hygiene habits. Therefore, the effect of teeth whitening is different from person to person and from tooth to tooth. Myth 3, teeth whitening is not durable will return to the original It is reported that after whitening the color of the teeth can be maintained for 1 to 3 years, even if the recoloration is only a few shades, will not return to the original state. However, the effect of teeth whitening still requires careful maintenance. Such as dietary control, to prevent the consumption of easily stained food, with the use of professional whitening toothpaste, regular home maintenance and other initiatives, will make the teeth whitening effect more durable.
