Just like brushing the teeth daily (naturally twice; during the day and last thing at night) the tongue should get the same treatment, you should make it a habit to finish off dental routine cleaning the tongue.
The tongue is a breeding ground for bacteria and when not cleaned, it causes everything from bad breath to infections. While with tongue brushing, using force is not encouraged, a way to know if you are doing it wrong is when you start to gag or bleed then you're using too much force, with gentle brushing the tongue will be cleaned of the mucus trapping the bacteria that are usually in abundance on the surface.
After brushing the teeth, use the bristles to gently brush the tongue in these easy steps:
1. After brushing the teeth, reach for the back of the tongue with the same brush of a tongue scrapper and then work this forward towards the mouth opening,
2. Brush the surface of the tongue using gentle strokes. Don't apply too much pressure so as not to tear into the skin which can open up the area to infection.
3. Rinse with water and spit just like you would brushing the teeth and you're done!
Brushing the tongue is one way to get rid of bad breath permanently and it's endorsed by dental experts so don't be afraid to brush away!
