Having Botox a few days after getting local anesthesia for dental work should not cause increased bruising or side effects. On the other hand, filler performed close to major dental work can have increased complications so more caution should be used. Best wishes.
Thank you for your question.It is very unlikely that the anesthetic from your dental procedure has anything to do with your bruising. Did you take any medications for discomfort afterward such as Ibuprofen or Motrin? Those type of medications can thin your blood and lead to bruising.
