British researchers looked at data from patients who received dental work, including simple procedures such as removing a tooth. They found those patients had nearly two times a greater risk of heart attack or stroke in the first four weeks after dental work than those who did not have dental work.
However, the researchers did not have access to information about the medications the patients were taking around the time of their surgery.
Researchers say there is not enough evidence to suggest people delay dental procedures, but they should speak with their doctors and dentists about any potential heart conditions.
The study is published in the Annals of Internal Medicine.
