Just Had Juvederm 2 Days Ago and Need to See Dentist. Its Not Emergency but the Sooner the Better?

You will want to avoid pressure in the area the filler is placed within the first few weeks of the treatment. Having dental work should not be a problem as long as there is no pressure placed on the area. I would recommend communicating with your dentist, and explain to him or her that you recently had treatment with filler in the nasolabial folds. I hope this helps, and best of luck to you.

In general, it is important to avoid the following things the first couple of weeks after you have filler:

1) Applying pressure to the area the filler was injected
2) Attempting to move the filler by massaging the area

If you have your mouth open wide in a dentist's chair for an extended period of time, it should not have a negative effect on your filler. If you really wanted to be safe, you can wait two weeks before having dental work. But this really is not necessary. Just let them know you had the treatment, and ask them to avoid putting pressure on your nasolabial folds. You are correct about the massage, and it is best to avoid that for a few weeks. But having dental work should not pose more of a concern than massage. 

      If a root canal or another significant procedure needs to be performed go to the dentist.  Otherwise, put off the appointment for a couple of weeks.
