Several external factors can cause the teeth to lose their natural color and shine. Teeth whitening is a process that helps brighten the color of the teeth and removes any discoloration or stains. It is most effective on the top layer of the teeth. This process is one of the most common treatments done in the country and worldwide.

Types
There are two main types of teeth whitening procedures that are done at a dental clinic. Vital whitening is only done on a tooth if it has live nerves. Whereas non-vital whitening is done on a tooth that has had a root canal treatment as it does not have any live nerves.

Vital whitening: This is the most common type of teeth whitening. A gel is applied directly to the surface of the teeth. A specialized laser is then used to activate the gel and, post this, the bleaching occurs. It takes about 30 to 90 minutes for this procedure to be done. It is done in around 1 to 3 sittings based on the extent and the requirement.

Non-vital whitening: The vital whitening procedure will not be effective in the case of a tooth that has undergone root canal treatment as the stain will originate from inside the tooth. In such cases, a whitening agent is placed inside the tooth and a temporary filling is done. You will have to redo this once every few years to retain the coloring.

Cost
The cost of teeth whitening depends on where you get it done. It also depends on the products used by the dentist. Another factor that determines the cost is the type of teeth whitening you need, i.e., vital or non-vital whitening. The condition of your teeth also plays a role in determining the number of sessions you will need. Usually, one session of teeth whitening costs about $500 on average.

The effects of teeth whitening last from a few months to 3 years. This varies from person to person and the maintenance of the teeth. The effects won’t last for long if you drink red wine, smoke, and drink coffee or tea. Any food that can leave a stain on teeth and cause damage to it should be avoided.

Home remedies
There are also some natural ways, such as the following, that can help make your teeth whiter at home.
