Crooked smile from fillers?

Question

I had fillers in my nasolabial lines months ago and since then, my smile appears crooked on the one side. Can fillers have this effect?

Steven F. Weiner, MD · Answer

It most likely is something which was pre-existing but you just didn't notice. If that's not the case, then it could be from Botox/Dysport in this area. I haven't seen weakness of the marginal mandibular nerve from injections before either.

Eric T. Carniol, MD · Answer

There may be several reasons for the crooked smile. First, it is possible that it existed before the injections and that it was just not noticed. Second, more filler could have been injected on one side versus the other. Third, filler could have been injected into a muscle. The good news is that if this is the case, it will dissolve. Botox and/or filler could be used likely. It is important to see a fellowship-trained expert! I wish you success!

Facial asymmetry is common and injecting fillers can make asymmetry appear more prominent in some cases after treatment.

Drew Varano, MD · Answer

Your left lower lip labialis muscle is slightly weaker than your right side causing a very slight asymmetry.( it doesn’t pull your lower lip down as much as the opposite side)  This was likely pre existing issue and now you are hyper focusing on it since you had a facial treatment . Filler does not affect the marginal mandibular nerve that innervates this muscle. If a local anesthetic was used then it can temporarily affect that nerve but it wears off in a few hours .

Hi,
Thank you for your question. Without seeing before the treatment photos, it is difficult to judge if fillers have caused or just emphasised slight asymmetry when you are smiling. You could check in with the medical practitioner who treated you. I think face to face consultation is the best option for a proper assessment of your situation.
