There are a number of ways to go about teeth whitening. The most common method involves the use of teeth whitening strips. Teeth whitening strips are small polyethylene pieces, which resemble flexible plastic that sticks to the surfaces, edges and crevices of your teeth.
According to CheadleHulmeDental.com, teeth whitening strips must be clinically approved. These strips are safe for use and the competition for this product is quite high in the market, which makes it difficult to point out the best ones available.
The strips should contain hydrogen peroxide or even carbamide peroxide that reacts with the moisture within the mouth and reaches teeth enamel, where stains usually settle. The peroxide is the whitening agent, while the urea acts to remove stain bonds, which allows the whitening to spread to other teeth.
Teeth whitening strips have studies to back it up. This has increased their sales worldwide through drugstores, dental offices and hospitals.
There are certified strips available over-the-counter (OTC). Whitening is as effective and safe, with some strips receiving the Acceptance Seal of different organisations as well. It is advisable to consult a dentist first. Additionally, certain whitening agents may cause irritation in the gum, tooth pain or hypersensitivity, which is treatable by painkillers or numbing gels.
Another factor to take into consideration before using a whitening strip is whether your teeth will respond at all to them. It is advisable to consult a dentist who can identify the type of tooth discolouration and recommend appropriate whitening methods. Brown and grey tinged teeth do not usually respond to whitening strips, while yellowish teeth surfaces respond well.
Be careful about following the instructions for application when using these strips. Incorrect application may cause extreme soreness or hypersensitivity. Prolonged use may lead to damaged tooth enamel and may affect the gum tissue as well.
