Church chipped a tooth on a piece of the hard candy about a week before reporting to camp. He felt pain off and on, but says it was unbearable when he woke up Monday morning.
The fourth-year pro missed a walkthrough and a full practice to get a root canal, but returned Tuesday.
Church says he "caught a couple of zingers" from coaches and teammates and isn't happy that he has to stay away from candy for a while.
Once he can eat candy again, Church says he'll "stick to the soft stuff."
Church missed the Cowboys' final 13 games last year with a torn Achilles' tendon.
