In the general population, low pH foods, such as acidic drinks, fruits and other products can be buffered to a certain extent by saliva, i.e. saliva will increase pH in the mouth to counter the drop in pH from these food and drinks. In dry mouth sufferers where the salivary flow is already low this can affect a person’s ability to buffer low pH from food and drinks. Use of oral care products with a pH of less than 5.5 could result in the loss of enamel from the tooth surface, depending on the level of saliva in the mouth. Therefore; for dry mouth sufferers, it is advisable that all oral products have a pH above 5.5 which is closer to normal saliva. This aligns to Dental professionals preferences for neutral pH products for people with low salivary flow.
