As a precautionary measure, it's advisable to avoid dental work or immunizations for four weeks after filler injections and one week prior. This strategy aims to minimize the risk of adverse reactions associated with filler procedures. Invasive dental procedures can lead to bacteremia, where bacteria enter the blood and may attach to dermal fillers as biofilms. Biofilms are clusters of bacteria that form a protective barrier, making them hard to eradicate and potentially causing inflammatory reactions around the filler. Over the years I have seen individuals who underwent dental cleaning immediately after filler injections were more prone to experiencing adverse reactions. Similarly, a filler reaction can occur following a vaccine administered shortly after the procedure. These responses are well documented in the medical literature. I would strongly advise you to space these procedures. Not what you wanted to hear but better safe than sorry.
