More than likely you have heard of the pH scale at some point in your life. But did you know how important this scale of measurement is in relation to your oral health? Understanding how to interpret pH measurements inside of your mouth can impact the overall future of your oral and dental health.
pH is a measure of how acidic or basic a substance is. pH stands for potential hydrogen and is displayed on a scale based on the hydrogens present. The scales range is from 0-14. Number below 7 are MORE acidic, 0 being the most acidic. Numbers above 7 are basic or alkaline. For example, water is neutral at about 7, in the middle of the pH scale, where’s something like battery acid is at a 0, and on the opposite closer to 14 is where you would find something along the lines of bleach or ammonia.
The pH level of the foods and drinks we put in our mouths directly affects our tooth and gum health. Drinks that are more acidic or a lower Ph include things such as black coffee, certain juices, sodas, sports drinks, and energy drinks. Similar to GERD, these drinks can cause the pH level in your mouth to drop significantly thus exposing your teeth and oral tissues to a more acidic environment. The opposite is true for more alkaline drinks higher on the Ph scale like water, dairy milk, and certain herbal teas, which are friendlier to our teeth and gum tissues as they do not encourage tooth erosion.
When you drink anything that is highly acidic, you risk the breakdown of your outer tooth layer of enamel. This constant erosion can cause sensitivity, discomfort, and increased risk of tooth decay and periodontal concerns.
Your dentist can see visible signs of enamel erosion during your dental exam. If you have concerns about erosion—especially if you have gum recession caused by periodontal disease—be sure to talk to your oral health provider.
