Could a dental problem be a possible cause of filler infection?

Yes, it’s quite possible that your dental issue could be related to your filler infection.  I recommend no fillers for one week after dental cleanings or procedures for that reason.

When I treat patients with filler, I tell them to try and avoid dental work for 1-2 weeks prior to and after the treatment to minimize risk of infection. Certainly, a dental infection could result in filler becoming infected. It's hard to comment on your case further without evaluating you in person.

Inflammatory reactions and nodules after injection with the products Voluma, Volbella and Vollure have been reported. These reactions have been reported weeks to months after injection and sometimes have been associated with recent dental work. Some people have felt that they are related to the development of a biofilm in the area of injection. It is hard to know if this is what you are experiencing without an in-person examination, so I would suggest following up with a trusted provider who is experienced in filler complications to discuss your case and treat your infection. When my patients get treated with filler, I do advise to avoid dental work in the weeks after injection to avoid potential complications such as these. Wishing you the best.
