Hi there! Thanks so much for reaching out. This is an excellent question. I would highly recommend holding off for a good two weeks before getting your filler, post your dental work. There is a lot of bacteria in the mouth and as things are disrupted, during your procedure, this can spread to other parts of the face. The area under the eyes is especially delicate and prone to inflammatory reactions, etc. post filler, and I am sure you do not want to increase your chance of any complications by having these two procedures done back-to-back. In the case that you decide to move forward with your filler appointment, make sure to let your practitioner know that you just had dental work done, so that they can take any precautions they deem necessary. Good luck! Ivette M. Ballara, RNRobinson Facial Plastic Surgery
