QUESTION:
What is the difference between the boil-n-bite moldable mouthpieces and the custom professional bleaching trays?

ANSWER:
Although both mouthpieces are safe, the precision lab-created bleaching trays are more precise and more comfortable to wear. These are the exact mouthpieces that a dentist provides. They help you save bleaching gel and are better for people who may have sensitivities to bleaching gels on their gums. Also, professional mouthpieces are much easier for you to create since there is no boiling water involved in the formation process.
