Our dental health status can literally govern what we can eat and how long for the rest of our lives we can still eat without external aids (like dentures) or painful surgeries, which will subsequently influence our overall health and even lifespan. The following techniques may improve our oral health, before it is too late.1,Pre-brushing flossing, the most recommended way for interdental cleaning(compared to toothpicks, etc), can effectively reduce tooth decay and gingivitis.2,Brushing for longer than two minutes each time may also help us remove more plaque from our teeth as the cleaning can get those hard-to-reach places. But we are advised not to brush too often (such as more than two times a day).3,Avoid brushing hard or using a toothbrush with hard bristles or abrasive toothpastes,as this can cause damage to our teeth and gums.4,Gargle with tap water after each meal.
