YOU MIGHT REMEMBER<\/b> a little bit about pH from a science class you took years ago in middle school or high school. Even if you don\u2019t, that\u2019s okay; it\u2019s time for a refresher course because pH plays a major role in our oral health.<\/p>\nThe Basics (And Acidics) Of pH<\/h3>\n
We could go into some really complicated things about hydrogen ions, but the important thing to know is that a pH of 7 is neutral \u2014 neither acidic nor basic. For example, water has a pH of 7. As the numbers get smaller than 7, the substance becomes more acidic,<\/strong> and as they get larger than 7 (up to 14), it becomes more alkaline or basic. Make sense? Good. Now let\u2019s look at what this has to do with our mouths.<\/p>\n Tooth enamel is the hardest substance in the human body, so it\u2019s pretty tough. It is, however, highly susceptible to acid erosion. All it takes is an environment of pH 5.5 or lower for the enamel to begin dissolving.<\/strong><\/p>\n There are many ways our teeth can be exposed to acid. The most obvious is when we eat or drink something sour or tart because we can actually taste the acid. When we consume something sugary or starchy, oral bacteria eats the leftovers stuck between our teeth and produces acid as a waste product.<\/strong> Acid reflux and vomiting also expose our teeth to stomach acid, which is very strong.<\/p>\n The best natural defense our teeth have against acids is saliva, which has a pH slightly above 7. Saliva washes food particles away and helps keep oral bacteria populations in check. This is why dry mouth is such a dangerous problem for oral health. The less saliva we have, the more vulnerable our teeth are.<\/strong><\/p>\n Sipping soda or snacking throughout the day is also a problem for our teeth,<\/strong> because saliva needs time to neutralize our mouths afterward, and constantly introducing more acid makes that much harder.<\/p>\n A great way we can help out our saliva in the fight to protect our teeth, aside from the usual methods of daily brushing and flossing and regular dental appointments, is to eat fewer acidic foods and trade them for alkaline<\/a> ones.<\/strong> That means adding in more fruits and veggies and leaving off some of the breads, dairy, and meats \u2014 and we should definitely cut back on soda and other sugary treats.<\/p>\nAcid Versus Tooth Enamel<\/h3>\n
