Meaning Behind
pH Levels
Potential hydrogen, or pH, levels refer to the chemical level of a substance and range from most acidic (0) to most alkaline (14) with a midpoint of 7 (pure drinking water). Normal saliva should remain between 6.2 and 7.6 pH, with a slightly higher alkaline level. The human body consists of about 60% water, and pH levels need to be close to that to sustain it.
Acidic pH describes substances that fall below a pH of 7, such as coffee, vinegar, and soda. Acidic substances cause acids in the mouth to demineralize, or break down, tooth enamel and expose the dentin. Dentin is the inner layer beneath the enamel; when exposed, teeth become sensitive to hot, cold, and sugary drinks.
Alkaline pH describes substances that rise above a pH of 7, including alcoholic beverages, seawater, and antacids. People with higher alkaline pH levels tend to have frequent dental problems.
