So one of the first clues is either a spouse or a loved one will mention to somebody that they have bad breath. Now that can be a couple of different things. It could be food stuck between the teeth or a coated tounge. And then when we brush our teeth we should brush our tounge…but if its food caught between the teeth then the bacteria are in play. And they will end up causing the bone to change and the gums to become swollen, reddened, and puffy. The lower teeth are more infected with the bacteria than the upper teeth. Sometimes this happens, since people will have a very strong lip muscle… and they can’t relax it so they can’t brush properly. Before you start brushing use a disclosing solution that colors the plaque which are invisible… and then you can use your dry brush, then your toothpaste. And then you re…redisclose…but I wouldn’t recommend it doing before you go to work or school… cause your teeth and gums will stay stay red.
