Why Do I Have Jaw (Toothache-like) Pain After Radiesse Injection?

Many patients describe a toothache-like sensation during injection with Radiesse.  However, pain after injection of only 1.8 mL several days later is atypical and requires evaluation by the Doctor who performed the procedure.

You didn't mention how many days ago your Radiesse was injected.  To have a deep pain many days later is unusual. If there were deep filling near the bone and the periosteum layer were touched then it might be tender for a while. It is worthwhile to see your doctor to ensure that there is no infection especially if you are having this much discomfort a week after the procedure. If it is only one day or two after, then you might notice improvement in a short period. If there is throbbing without touching the area bring this to your doctor's attention immediately.

This is highly unusual. You may want to disccuss it with your surgeon. My guess is that there may be another cause.

Given your symptoms there may be nerve damage with the injection, or an unrelated cause that should be addressed. Talking to your injecting physician is recommended.

Radiesse can have some lingering deep "aching" pain afterwards. The Herpes simplex out break you have had is another indication of "nerve irritation" that can result in pain. I always counsel my clients that this may go on for a couple of weeks, (gradually decreasing in severity), and responds well to ibuprophen, which in addition to relieving pain, reduces the inflammation that presumably leads to the pain in the first place. if you have another injection session, make sure you get some anti-Herpes oral medicine like Valtrex to start taking the day before. this should avoid the canker sore issue and my decrease the pain as well.

Radiesse in correctly injected deep, often just above the bone. This can result in deep pain, especially if you needed more material and bruised more on that side, or if a nerve was traumatized. Talk to your doctor and have it checked, but odds are it will resolve in a week or so. Warm compresses and gentle massage several days AFTER the injection (not immediately after, as this can worsen the bruise and pain) can sometimes help the discomfort. 

One likely explanation is the filler material has come into contact with the ends of the mental nerve which supplies the feeling to the lower lip and chin area. By irritating these nerve ends, the pain may be radiating back into the jaw where the nerve exits before it comes out into the lip area. This is very uncommon (the first I have heard of it) and it will likely eventually subside. You can try some massage of the area particularly if you can feel any lumpy areas where the material deposition is most dense.
