White smile is a source of pride for every person who cares about beauty. That’s why teeth whitening is a popular procedure on which you can find a lot of information on the Internet. Let’s take a closer look at this issue. Familiarize yourself with the causes of yellowing and learn how to whiten your teeth safely so that the effect is visible and lasting.
Why do teeth turn yellow?
The natural color of the teeth is an individual feature and depends on many factors. Over time, the teeth change color. There are two reasons for yellowing teeth. First, over time, the enamel becomes thinner and this is the reason for the darkening of the teeth. Secondly, the color of the teeth is affected by the type of food consumed, because the teeth absorb the dyes. That is why in older people the teeth change color to more yellow.
There is one more reason for the darkening of the teeth resulting from incorrect treatment. If after the treatment the dead pulp tissue remains in the tooth, then the tooth gradually darkens. The cause may also be blood entering the tooth cavity, or the use of poor quality canal filling materials by the dentist. This type of discoloration can also be removed, but in this case it is not enough to use a whitening gel and it is necessary to re-open and properly fill the teeth.
Is teeth whitening safe?
Teeth are bleached by oxidation of dyes that accumulate in the tissues. For this purpose, chemicals are used in the form of a gel that is applied to the teeth. The most commonly used chemical compounds are hydrogen peroxide and carbamide peroxide. In the past, baking soda was commonly used to whiten teeth, which is currently a component of many tooth whitening pastes. According to dentists, bleaching substances used in the offices are completely safe and do not damage the teeth. A minor ailment after the procedure may be hypersensitivity of the teeth, which is the result of drying the tissue, and which disappears after a few hours.
Professional teeth whitening
If you have money that you can spend on this purpose, then this is the best option. You can have a nice smile easily and quickly. Even if you do not like visits to the dental office, there is nothing to fear in the case of teeth whitening. The treatment lasts about an hour and is painless and the effects can be seen immediately. Whitening gels are becoming more and more effective. There are also special high concentration gels that are activated by the light of the lamp.
Teeth whitening at home
Teeth whitening can also be done by yourself at home. There are the same gels on the market that are used by professionals. You can also buy sets with a specialist lamp that accelerates and preserves the effects of whitening. Teeth whitening at home is definitely cheaper. Remember, however, that your teeth grow only once and you may want to meet your dentist before applying unproven preparations and make sure that the agent you want to use is certainly safe.
