Hydroxyapatite (dental, bone use) (Hydroxyapatite) — Uses, Dosage, Side Effects & Safety

Drug class: Musculoskeletal & Connective Tissue

Overview

Hydroxyapatite is a naturally occurring mineral form of calcium apatite, closely resembling the mineral component of human bone and teeth. It is widely used in dentistry to help repair and remineralize tooth enamel, and in orthopedics as a bone graft substitute to support bone regeneration and healing. In dental care, hydroxyapatite can be found in toothpastes, creams, and varnishes designed to reduce tooth sensitivity, strengthen enamel, and prevent cavities. In surgical and orthopedic settings, hydroxyapatite is used as a scaffold or filler to promote bone growth in procedures such as bone defect repair, spinal fusion, and dental implants. Patients should know that hydroxyapatite is generally well-tolerated, biocompatible, and does not cause allergic reactions in most people. It is not absorbed systemically when used topically or as a bone graft, making it a safe choice for many dental and orthopedic applications.
