The purpose of our study was to assess whether the chemical composition of drinking water in the city of Szczecin, Poland, creates the correct environment in the oral cavity for promoting regeneration processes in the mineralized tissue of teeth. The drinking water samples were collected from a water treatment station, as raw and treatment water, and from consumer’s water pipes. The concentration of calcium and magnesium was determined by F-AAS method, fluoride by ion-specific electrode, and pH by pH-Meter. The average concentrations of calcium (46.9 mg/dm³), fluoride (0.73 mg/dm³), and pH level (7.46) determined in tap drinking water create a sufficient environment in the oral cavity for promoting regeneration processes in tooth mineralized tissues. Because of the low concentrations of magnesium in drinking water (14.1 mg/dm³), this element should be supplemented in a person’s diet.
