White sugar and honey toothpaste does not play a role in whitening teeth, because neither sugar nor honey has the effect of whitening, and brushing teeth with toothpaste containing white sugar for a long time, it is easy to suffer from dental caries, so it is recommended that the patient is still using ordinary toothpaste for brushing teeth is better. If patients do have the need for whitening, they can consider going to the hospital for cold light whitening. Cold light whitening requires the application of 30% hydrogen peroxide gel on the surface of the teeth, and then irradiate the surface of the teeth with cold light generated by the instrument, which can achieve a certain degree of whitening effect in about 45 minutes, and the whitening effect is not permanent, but can be maintained for about 3-5 years.
