A healthy mouth, which is non-acidic and neutral, has a pH of 7.0 or above. The teeth’s roots start to dissolve once the level goes below the average pH of 6.5. When the acidity drops to pH 5.5 or lower, a tooth will begin to erode, increase its risk for cavities and become discolored.
Acidity and Your Teeth
Gentle Dentiststates that acidity damages teeth, but it is the amount of time acids remain in your mouth that determines the extent of erosion they inflict. The decay and erosion of tooth enamel worsen when you consume highly acidic drinks like sodas and juices. To keep your teeth healthy and protected from all sorts of bacteria and disease, it is ideal to keep acidity at a minimum level. When your mouth has a pH level of 7.5 or above, your teeth actually become stronger because of the re-mineralization that occurs.
It is common knowledge that drinking too much soda damage teeth, but other beverages are also acidic and damaging. These include energy drinks, citrus juices, and tea. You don’t have to avoid these altogether; however, you must watch your consumption because it affects the pH level of your mouth.
Your mouth has a natural defense against damaging acids – saliva. People with acidic mouths have the highest risk of developing dental problems, like enamel erosion and tooth decay, because their own acidic saliva damages their teeth.
The food and drinks you consume play an integral role in the pH level of your mouth. What you put in may cause fluctuations in pH levels from high acidity, like citrus fruits, wines, and juices at pH 2.2 or lower to alkaline levels of pH 8.5 or higher from salty nuts and chicken soup.
