Should I reschedule dental cleaning booked for 4 days after cheek filler?

It may be possible to seed freshly placed filler with oral bacteria after a dental cleaning. It would be advisable to take a prophylactic dose of antibiotics before your cleaning.

Hello! Yes. I would recommend rescheduling one or the other. Filler is technically an implant (although a non-permanent one). When dental cleanings are performed, some of the bacteria from the gums and teeth can get into the bloodstream and get deposited on implants. This is why patients with some implants (such as mechanical heart valves) always get antibiotics when they get their teeth cleaned or have other dental work done. So as a general preventive measure (although I recommend good dental care as well), I would recommend spacing your filler and dental appointments out by about 2 weeks or more. Wish you all the best!
