Having teeth whitening treatment could help people to achieve their goals, it has been suggested.

According to WorlDental.org, having a whiter smile projects a concern about a person's own physical appearance, which encourages others to take them more seriously.

In turn, this increases their levels of confidence and decreases self-doubt.

"And as we all know, confidence, when not used in excess, can be a very powerful tool in the execution required to achieve one's goals," the article commented.

This follows a study published by Nutrition and Diet News which suggested that teeth whitening could indirectly lead to people feeling happier.

It explained that smiling more as a result of having better teeth may lead to the release of more endorphins.

It could also make other people feel happier when they receive a smile, the publication said.

Laser teeth whitening could be an option for those who want to achieve quick results.
