If you are looking for a reliable, effective teeth whitening agent, we have a whitening pen so good from Mirawhite, it can remedy discoloration resulting from any number of reasons. It dispenses a professional bleaching gel called Mirawhite Oxygen, which you brush on where needed. Simply allow it to work for up to 10 minutes and rinse. About a week later, you can behold the improvement at its peak. The pen contains about two treatments, so you can apply again in six months.
Because the Mirawhite Oxygen is considered a medical product, we recommend first consulting your dentist, especially if you have gingival problems or hypersensitivity to any ingredients. If either of these conditions exists, you should refrain from using the product. The combination of propylenglycols, polyglycols, 16% carbamide peroxide, and aqua is otherwise safe, and dentists use it for bleaching.
