A recent study has revealed that peroxide-based whitening mouthwashes have no whitening effect on stained teeth after a 21-day application period. The levels of hydrogen peroxide in these products are too low to cause any damage to gums or oral tissue. However, many rinses and whitening products can increase tooth sensitivity, and alcohol-based mouthwashes can cause dry or irritated mouths, according to Gigi Meinecke, D, M, D. Once you've completed your professional teeth whitening treatment, it's important to take steps to maintain the results.
Fortunately, keeping your teeth looking their best isn't difficult and professional treatments can be repeated as needed. Tetracycline and minocycline staining affects the dentin layer underneath the enamel, so prolonged bleaching may be necessary for the gel to reach this inner layer. The results of this study showed that the amount of time that stained teeth were submerged in mouthwash was an important factor in teeth whitening. Additionally, women's teeth are typically whiter than men's because their teeth are smaller and have less dentin.
Professional teeth whitening usually takes about an hour and then you're ready to show off your pearly whites. The compounds used in these treatments have whitening properties and can penetrate beyond the enamel to the inner layers of the teeth for a complete whitening effect. Professional teeth whitening uses solutions designed to penetrate deep into the tooth surface to break up and remove stains and dirt. Whitening mouthwashes, when used with effective whitening toothpaste, can also achieve great results.
A previous study reported that the staining of bovine and human teeth was similar, as were the effects of whitening. However, the effectiveness of whitening mouthwashes may be diminished by the fact that they are in contact with the teeth for a short period of time compared to whitening gel for household use. Fortunately, teeth whitening has a very limited impact on the color of materials used in crowns, bridges, and implants. Therefore, this study evaluated the whitening effect of three mouthwashes containing HP compared to 10% carbamide peroxide (CP) used in homemade whitening gels at different periods of immersion.
Professional teeth whitening is done in the office or using home kits prescribed by the dentist. Within the limitations of this in vitro study, each of the mouthwashes tested increased tooth whiteness over time. Toothbrushes, when used with effective whitening toothpaste, can effectively remove persistent stains and any other coating on the teeth. When performed correctly, teeth whitening can generate tremendous benefits, especially when using the right products.
An effective toothbrush for whitening teeth should have polishing bristles that help remove stains. If used regularly over a 6-week period, whitening toothpastes can make teeth significantly whiter.
