Poor Oral Health Raises Jaw Necrosis Risk in Breast Cancer
Researchers conducting a Finnish registry study found that poor oral health increased the risk of jawbone necrosis among breast cancer patients receiving antiresorptive treatment.

The Finnish study focused on patients with advanced breast cancer that had spread to bone. The researchers identified oral health as an important factor in medication-related osteonecrosis of the jaw, in which jawbone tissue dies.
Risk during bone-directed treatment
The study team described antiresorptive drugs, which reduce bone breakdown, as an important part of treatment when breast cancer has spread to bone. The researchers also linked these medicines to a risk of medication-related jawbone necrosis.
In the Finnish registry study, the researchers diagnosed jawbone necrosis in 12.6% of patients treated with denosumab. This figure comes from a registry population with advanced breast cancer and should not be treated as an individual prediction or extended to other patient groups without further evidence.
Why oral health matters
The researchers found that poor oral health increased the risk of jawbone necrosis in breast cancer patients. Their finding supports giving oral health particular attention when antiresorptive therapy is being considered or used.
Frequently asked questions
Why are antiresorptive drugs used when breast cancer spreads to bone?
The Finnish study team described these drugs as an important part of treatment because they reduce bone breakdown. Their use can also be associated with medication-related jawbone necrosis.
Does poor oral health affect jawbone necrosis risk?
Yes. Researchers conducting the Finnish registry study found that poor oral health increased the risk among breast cancer patients. Because the evidence came from a registry population with advanced disease, it does not predict any one patient's outcome.
Questions for the treating team
- How will my oral health be assessed before or during antiresorptive treatment?
- How does the risk of jawbone necrosis apply to my treatment plan?
- Does my treatment include denosumab or another antiresorptive drug?
