Brushing our teeth could help us burn calories and stay slim, it has been claimed.

According to the San Diego News Network, ensuring that our pearly whites are gleaming burns two and a half calories per minute – and experts say we should spend at least two minutes every day doing so.

Writing for the news provider, Jennifer Reed commented: "Don’t forget that swishing mouthwash and flossing will also burn calories. To add some exercise into your routine, try doing squats while brushing."

She added that using a timer while doing this and brushing will help us lose weight and have great-looking legs, as well as spend the appropriate amount of time cleaning our teeth.

Earlier this week, it was revealed that dentists all over the world are recommending teeth whitening bleach as an excellent way to achieve a shiny white smile, with many stating that bright teeth can help people who are looking for a job achieve success.
