Which ingredient in toothpaste is effective for controlling tartar buildup?

Pyrophosphate is an ingredient commonly included in toothpaste formulations specifically aimed at controlling tartar buildup. Tartar, also known as calculus, forms when plaque hardens on the teeth. Pyrophosphate works by inhibiting the precipitation of calcium phosphate, which is a key component of tartar formation. By interfering with this process, pyrophosphate helps to keep the teeth cleaner and can reduce the amount of tartar that develops.

Fluoride, while crucial for preventing tooth decay and strengthening enamel, does not directly address tartar control. Additionally, calcium carbonate is primarily used as an abrasive to aid in the mechanical removal of plaque but does not have properties that actively prevent tartar formation. Triclosan has antibacterial properties and was used in some dental products to reduce plaque and gingivitis, but it has not been recognized specifically for tartar control compared to pyrophosphate. Thus, pyrophosphate’s targeted action makes it the effective choice for controlling tartar buildup in toothpaste.
