6 weeks ago I had to have a filling replaced with a composite filling and I also had a
crown on one of the last lower molars. I had issues with the temporary
crown, and those were quickly resolved by my dentist. Last week, my new crown was put in place and I also seemed to.be having some sensitivity issues. The dental assistant used something along the gum line that would be temporary, eventually wearing off. Currently, the tooth with the composite filling is hurting.
