Will the dental work affect the Juvederm injections or should I wait till all my dental work is done to proceed?

I suggest you wait. Often there is a lot of tissue manipulation by the dentist to gain access to your dental issues.

There are some rare instances of infections following dental infections or procedures in the area that fillers were placed.  I is known that there is some bacteria that flows through the blood stream during these procedures and sometimes they can get stuck in the area of filler and lead to infection.  Freshly placed filler will be more inflamed and have more blood supply than something that has been there for awhile.  I would wait and tell all my patients the same.
