Did you notice any white coating on your tongue? The white coating found on the tongue are actually formed by countless of unusual microbes known as biofilm. There are usually many accumulated bacteria found on the tongue which will cause bad breath.
Proper oral care and tongue brushing can help to minimize the problem. You can either use a tongue cleaner or toothbrush to eliminate the white coating on the tongue. This can help to lessen the bad breath. We have to do these steps repeatedly daily because the biofilm cannot be eliminated forever and will reestablish itself again after a while.
The white coating on the tongue can also be caused by dry mouth. If you are not drinking enough water, it is quite likely that the food particles left on your mouth will stick onto the tongue. Water will help to flush away the food particles and will minimize the chance of food particles sticking onto the tongue. Avoid drinking milk based products such as coffee, milk tea or even soy milk which can also be the contributing factors to the white coating. Besides brushing your teeth 2 – 3 times a day, you should also floss and clean your tongue. You should also visit the dentist every 6 months.
