If you want to keep your mouth cleaner than through brushing and flossing alone, an interdental cleaning device might be the answer. These devices work by scrubbing between each tooth and sending a vibrating current down its length when brushing.
Interdental devices include items such as a water flosser, an electric toothbrush, or any device that uses vibrating currents to better clean your teeth. It is important to consider whether these devices are for you by consulting your dentist, as certain dental conditions such as periodontitis may cause your teeth or gums to be too sensitive for interdental devices.
