When it comes to protecting your teeth, most of us are familiar with fluoride toothpaste. For decades, it has been the go-to option for preventing tooth decay and strengthening enamel. Fluoride works by remineralising weakened enamel and making it more resistant to acid attacks from bacteria.
Hydroxyapatite toothpaste, however, is quickly becoming a favoured alternative. Hydroxyapatite is a mineral that naturally makes up around 97% of our tooth enamel. When used in toothpaste, it doesn’t just coat the tooth surface – it integrates directly into the enamel, filling microscopic cracks and smoothing rough areas. This makes it the biocompatible option as it works with your body’s natural structure.
Both fluoride and hydroxyapatite play a role in fighting tooth decay, but hydroxyapatite offers additional benefits. Unlike fluoride, it is non-toxic if swallowed, making it a safer choice for children. It also helps reduce tooth sensitivity by sealing exposed dentinal tubules and contributes to whiter teeth by creating a smoother, glossier enamel surface.
For patients who want an effective, science-backed option without potential concerns about fluoride, hydroxyapatite is an excellent choice.
