Alendronate and dental implant healing
Can you get a dental implant on alendronate (Fosamax)? What the evidence shows about bisphosphonates, osseointegration, and MRONJ risk in implant patients.
Never start, stop, or change a medication based on what you read here. Bring questions to your dentist, physician, pharmacist, or prescribing clinician.
Quick answer
Dental implants in patients on oral alendronate generally have success rates close to non-users. The MRONJ concern is real but rare with oral bisphosphonates, especially for short and medium durations of use. The risk rises with treatment beyond four to five years and is much higher with IV bisphosphonates used in cancer treatment. Most patients on Fosamax can get implants safely with appropriate planning and post-surgical follow-up.
The mechanism
Why bisphosphonates affect implant placement
Implant success depends on osseointegration: bone growing into the surface of the titanium implant. This requires active bone remodeling, the same process bisphosphonates slow down. The intuition is that bisphosphonates would impair osseointegration, but the clinical reality is more nuanced. Multiple studies show that oral bisphosphonate users have implant survival rates similar to non-users in the short and medium term.
The bigger concern is MRONJ (medication-related osteonecrosis of the jaw). The risk is concentrated at surgical trauma sites, which includes implant placement. For most patients on oral alendronate for less than four years, the absolute risk is low (well under 1 percent in studies), but it is not zero. For patients on IV bisphosphonates used in cancer treatment, the risk is meaningfully higher and changes how dental surgery is planned.
The risk profile also depends on the implant site (posterior mandible is highest risk), the surgical technique (more invasive placement raises risk), and other factors like steroid use, smoking, and diabetes. A patient on five years of oral alendronate with no other risk factors is a different conversation than the same patient with multiple risk factors stacked.

Signs to watch for
When to call your dentist after implant surgery
- An area of exposed bone in the mouth, even if not painful.
- Pain that gets worse after day three instead of better.
- Swelling or pus from the surgical site.
- The implant feels loose or wobbly at any point.
- A non-healing socket or surgical site weeks after the procedure.
