Scientific studies show that the tongue is a prime contributor to bad breath and other oral health problems. Especially during sleep, the tongue is coated with a plaque film of bacteria and other odor causing compounds. This is why even after brushing your teeth, fresh breath is difficult to maintain. The bacteria on the tongue is also a potential contributor to periodontal problem and other oral health problems. This coating on the tongue also causes a loss of taste. Brushing the tongue with a toothbrush is not effective. This only stirs up the undesirable material on the front area of the tongue but does not remove it. The Tongue Cleaner is scientifically designed to effectively clean the tongue, including the important, hard to reach rear portion of the tongue. The Tongue Cleaner removes the cause of the problem, unlike mouthwash and breath aids, which only cover up the problem temporarily.
