The key to cavity prevention: pH in the mouth

Acid produced by bacteria in the mouth is the cause of cavities. Bacteria in your mouth is the plaque that you brush off your teeth and the tartar that your dental hygienist removes from your teeth at your regular cleanings.

The pH scale goes from 1 to 14, with 1 being the most acidic, 14 being the most alkaline and 7 being neutral (like most water). A pH of 5.5 is an important pH level for teeth, as the teeth begin to dissolve or demineralize/break down at a pH in the mouth below 5.5.

Food and drink change the pH of saliva. Age may be a factor also, as children have an average saliva pH of 7.5, while adults tend to be more acidic, with a saliva pH of 6.5 or lower. There are some products too that have low pH levels, such as Listerine (from 3.4 to 3.5 pH) and Crest (3.6 pH), but Biotene has a pH of 6.2.

An “acidic mouth” contains chronic excess acid in the oral cavity resulting from frequent consumption of sugary foods or drinks high in acid content. Dry mouth, also known as xerostomia, can also cause an increase in acid in the mouth and elevate cavity rate. Also, some fungi found on the roots of teeth can increase crib caries (cavities) in children.

To test the pH in your mouth you can use any pH strips that are used to test acidic items. Wait at least two hours after eating or drinking to ensure that the food consumed does not alter the test results. Cleanse your mouth by filling your mouth with saliva and then swallowing or spitting. Fill the mouth again with saliva and place a small amount on the pH strip. The strip will change colors based on the results.
