What Are Bisphosphonates and Why Do They Matter in Dentistry?

If you take medications for bone health—like Fosamax or Reclast—your dentist needs to know. Here’s how bisphosphonates impact extractions, implants, and healing.

At Pecan Tree Family Dentistry, we always review your full medical history before recommending treatment. One group of medications we ask about specifically is bisphosphonates—commonly prescribed for bone loss but highly relevant to dental care .

💊 What Are Bisphosphonates?

Bisphosphonates are medications used to prevent or treat bone density loss. They are most often prescribed for:

  • Osteoporosis
  • Paget’s disease
  • Bone cancers or metastases
  • Multiple myeloma

These drugs slow the breakdown of bone by inhibiting osteoclasts (bone-resorbing cells), helping maintain or increase bone strength .

Common Bisphosphonates Include:

  • Alendronate (Fosamax)
  • Risedronate (Actonel)
  • Ibandronate (Boniva)
  • Zoledronic acid (Reclast, Zometa – IV form)

🦷 Why Do Dentists Need to Know About These Medications?

While bisphosphonates strengthen bones, they also affect the jaw’s ability to heal after dental procedures. This is especially important before:

  • Tooth extractions
  • Dental implant placement
  • Jaw surgery

A major concern is a condition called Medication-Related Osteonecrosis of the Jaw (MRONJ)—a rare but serious complication where the jawbone doesn’t heal properly, leading to exposed bone, infection, and long-term damage .

Key Risk Factors:

  • Long-term or high-dose bisphosphonate use
  • IV bisphosphonates (higher risk in cancer patients)
  • Trauma to the jawbone from surgery or ill-fitting dentures

🛡️ What You Should Do if You Take Bisphosphonates

To stay safe:

✅ Always tell your dentist if you’re on any bisphosphonate (pill or IV)
✅ Avoid unnecessary oral surgery or trauma
✅ Keep up with cleanings to reduce infection risk
✅ Ask about alternative treatments when possible
✅ Don’t stop medication without talking to your doctor

In some cases, your dentist and physician may coordinate a temporary “drug holiday” from bisphosphonates prior to surgery—but this should always be done under medical supervision .
