I got a temporary crown because my molar was found to be cracked when my old silver filling was removed. NO root canal was indicated so a new filling and temporary crown put in immediately. I developed mouth sores on the inside of my cheek, gums near the tooth and by the lips which was treated with acyclovir. Its been over a week and now resolving. Now I feel like the treated tooth is tight and pressurized. It also throbs which I have been treating with Ibruprofen. Is this a normal sensation from the temporary crown? Or is there pressure due to swelling and inflammation from the sores and dental procedure from over a week agao?
