Burning lower lip and sensitive lower teeth normal after v-line surgeryand SMAS facelift?

While the symptoms you describe can
be disconcerting, I can assure you that they're normal and may actually
indicate that your nerves are "waking up" from anesthesia, healing
themselves, and regaining their normal functions. I don't have any reason to
believe you're suffering from a serious secondary condition such as trigeminal
neuralgia. That said, it's always good to express your concerns to your surgeon
during your follow-up.

Thank you for your question.  It sounds as if you may have some numbness and/or stretching of the nerve which supplies feeling to the jawline.  This is the mental nerve, and can be stretched during this procedure.  That you are getting a 'burning' sensation is actually a good sign, in my opinion.  This means that the nerve is recovering.  I would discuss your concerns with your surgeon, as well, as he/she knows exactly what was done in your procedure.  I hope that this helps!-David Gilpin

Any procedure that is performed to contour the chin has the potential to produce sensory disturbances in the distribution of the inferior alveolar / inferior mental nerve.  These nerves may be stretched or simply swell because of the surgery performed in the area causing  the symptoms you are describing.  Since your surgery was recent the liklihood these problems will resolve is highly probable.  Regards.
