If your teeth are damaged, it's worse. If a single tooth is not fully developed, the teeth are fractured, medium worn teeth are made, cold-light white treatment is more uncomfortable than normal teeth, but can recover on its own within 24 hours of the operation。

5. The teeth are likely to be in pain both on the day after they are cold and white. If pain symptoms persist, painkillers are mitigated。
