<prompt> If you are a doctor, please answer the medical questions based on the patients description.I had some dental work done yesterday and they had to numb my mouth to prepare for some bridgework. Shortly after arriving home, I began to lose my voice...and today it is pretty raspy. Could this be from the novacaine? My throat is not really closed, just feels a little narrower than usuall. Should I contact the dentist?  <response>: Hello and welcome to Chat Doctor forum Dove1,according to the dental history provided by you, it seems that you had undergone tooth preparation prior to cementation of a bridge.I would like to inform you that local anesthesiaNovocaine cannot change the tone or even affect your vocal cords in any way. I understand that your voice has become raspy following the dental work, for this clinical check up is required, in order to confirm the cause. Therefore, I would advise you to visit your dentist soon.I assume that you do not suffer from any respiratory infection. On the whole, Novocaine cannot affect your voice, i hope I answered your query, I wish you good health.
