Can swimming pool water affect your teeth? The answer involves far more than chlorine.
In Episode 34 of the Pool Envy® Podcast, we explore the strange case of swimmer’s calculus — and use it to examine the chemistry connecting our teeth, saliva, swimming pool water, and mineral saturation.
We begin with the acquired enamel pellicle, the microscopic protein-rich layer that forms on teeth, including proteins such as statherin, histatins, cystatins, lysozyme, and alpha-amylase. From there, we examine dental calculus, calcium-phosphate mineralization, hydroxyapatite, and documented dental erosion among frequent and competitive swimmers.
Then we bring the chemistry back to the swimming pool.
What happens to carbonate chemistry as pH changes? How are pH, alkalinity, calcium hardness, and mineral saturation connected? Why can calcium carbonate either remain dissolved, precipitate as scale, or become vulnerable to dissolution from calcium-containing pool materials?
We use those questions to explore the Langelier Saturation Index (LSI) and an important concept often missed in swimming pool water chemistry: individual test results cannot always be interpreted independently.
We also explain an important distinction between dental and swimming pool chemistry. Tooth enamel consists primarily of hydroxyapatite, a calcium-phosphate mineral, while LSI describes saturation with respect to calcium carbonate. They are different mineral systems, but both demonstrate why pH, dissolved minerals, saturation, and the surrounding chemical environment matter.
This episode may be especially interesting for dentists, dental hygienists, orthodontists, endodontists, prosthodontists, restorative and biomimetic dentistry professionals, competitive swimmers, aquatic professionals, swimming pool operators, and water chemistry professionals.
