I had a crown put in about 2 weeks ago. During the initial stages of the procedure, when the numbing agent was used, I experienced a burning sensation down my throat. The remainder of the 2 hour procedure went well, although so much anesthesia was used that I had some difficulty swallowing. The next day my throat was very sore and I was having shortness of breath. My voice was raspy and I would lose it after any conversation of any length. When this persisted for 3 days I called my dentist and he said that it may be due to swallowing some of the numbing agent which caused scouring of the throat. He prescrived an anti-microibial gargle/rinse to be used twice a day to ward off any infection. It now is 12 days post-procedure and I stilll have a sore throat, the glands on the same side of my neck as the dental work are sore and seem swollen, and my hoarse voice is reduced to a whisper after a normal conversation of 5 minutes. I d like your opinion about what s going on. Thank you.
