Water picks, also known as oral irrigators, are devices that use a pulsating stream of water to remove plaque and bacteria from between teeth and below the gum line. They are often recommended by dentists as a way to improve oral hygiene and prevent gum disease.
Water picks are particularly effective at removing plaque and bacteria from areas that are difficult to reach with a toothbrush, such as the back of the teeth and between the teeth. They can also help to massage the gums and improve circulation. Some water picks also have a flossing feature that can help to remove plaque and bacteria from between the teeth.
