Study of Oral Moisturizers Concludes that OraCoat ® XyliMelts® Contain One of the Safest pH Levels of any US OTC Dry Mouth Product

The objective of the study was to measure pH levels, titratable acidity, and erosive effect of commercially distributed dry mouth lozenges and adhering discs on teeth, mainly the dentin which is exposed at the gumline. Each product was crushed into five grams of powder and dissolved in 10 mL of water. Acidity was measured with a calibrated pH meter. Titratable acidity was measured by adding sodium hydroxide until the solution reached neutrality. Erosion of tooth structure was measured by placing human teeth in the solution and measuring loss of mass.In order of danger, the most dangerously acidic dry mouth lozenges and adhering discs were reported to be:DenTek® OraMoist®, pH 2.9Cotton Mouth Lozenges®, pH 3.1MedActive® Oral Relief Lozenges, pH 3.2Hager Pharma Dry Mouth Drops, pH 4.44Rite Aid Dry Mouth Discs, pH 5.1CVS Dry Mouth Discs, pH 5.3ACT® Dry Mouth Lozenges, pH 5.7TheraBreath Dry Mouth Lozenges, pH 5.82Moreover, the oral moisturizers that caused the most tooth erosion were, in order:Cotton Mouth Lozenges, 3.1% lossDenTek OraMoist, 2.3% lossMedActive Oral Relief Lozenges, 1.1% lossRite Aid Dry Mouth Discs, 1.1% lossCVS Dry Mouth Discs, 1.0% lossTheraBreath Dry Mouth Lozenges, 1.0% lossThe study found a robust statistical correlation between high acidity and tooth loss. Both remedies that passed the acidity test, XyliMelts and Salese, contain a pH level of 8.0, which is considered non-harmful to teeth. Previous studies reported that pH below 6.7...
