At some point in time, most people have looked in the mirror at their teeth and wished they could be a little bit whiter. Teeth whitening is a concept that comes surrounded by lots of myths. It is important when considering whitening your teeth to know what processes are proven to work and what teeth whitening techniques are a waste of your time.
Why teeth turn yellow
Many people believe that staining of teeth is primarily caused by consuming stain-causing foods such as coffee, soda, tea, and red wine. However, these stains can be dealt with by brushing every day and paying regular visits to your dentist.
The real reason teeth often turn or look yellow is because, beneath the outer layer of tooth enamel on each tooth, there is a yellowy core of dentin. When the enamel on your teeth is worn down by eating acidic foods, grinding your teeth, or natural aging processes, teeth can appear more yellow.
The yellowing of your teeth and the thinness or thickness of your enamel is also partially determined by genetics.
Two main whitening methods
The American Dental Association states that there are two main ways to whiten teeth effectively. The first of these ways is to use chemical agents that bleach the teeth by penetrating the enamel and eliminating some of the yellow in the dentin.
The second method of whitening is to use abrasive techniques to remove surface stains from teeth. This method can be achieved through regular use of whitening toothpaste, whitening strips, and other drugstore solutions.
However, many dentists believe that the bleaching method, which is usually done in a professional setting, can be more effective and potentially less damaging to teeth. Abrasive whitening products do not penetrate to the dentin, and if they are used incorrectly, can cause damage to the enamel or your gums due to the abrasion. This excessive abrasion could backfire and increase the yellowing of your teeth.
Few dentists will enthusiastically recommend the use of whitening toothpaste. Some whitening toothpastes do contain the bleaching agents necessary to whiten teeth, and they are not exposed to the teeth long enough to be effective.
Other, cheaper toothpastes rely on abrasive whitening techniques, which some dentists compare to using sandpaper on teeth. These toothpastes can be damaging by scrubbing away dentin and enamel and will not have a strong whitening effect.
Most dentists recommend ordering custom whitening trays instead of most drugstore whitening strips to avoid any accidental bleaching agent getting on your gums and to reach the curves of the teeth. These can be more effective than toothpastes from the drugstore, just make sure to check with your dentist about the safest methods.
