Angry West Ham boss David Moyes accused his players of lacking fight after they escaped from Shrewsbury with an FA Cup replay. After Cheikh Kouyate failed to get a telling touch to a unsafe cross by Cullen in the ninth minute, any whiff of a first-half breakthrough by the away team vanished.
The 21-year-old received treatment on the pitch as blood poured from his mouth while a member of West Ham's medical team picked the stray tooth out of the turf.
League One promotion chasers Shrewsbury grew more and more into the contest, however, and had a couple of big chances to open the scoring. The keeper's first save, admittedly, was more straightforward than it might have been, the goalkeeper needing only to fall on the ball to snaffle a scuffed effort by Ben Godfrey after West Ham's failed to deal with a free-kick by Shaun Whalley. And, as the first half progressed, they forced Hart, at least, into earnest action.
A repeat of that result this afternoon would be a blow to fan morale at West Ham, even if Moyes might tacitly appreciate the chance to focus on the Premier League relegation battle.
"I was a substitute against BATE Borisov in a Europa League game and I was called to get stripped to come on - but I didn't have any shinnies". Hart was busy in the first-half in particular, where he made saves to keep out Mat Sadler and Alex Rodman.
"We are going to be on the back foot now and again, but hopefully we can ride the storm, catch them on the break and see what happens".
He said: "I've seen us do better but we haven't come up against individuals as good as today".
"The atmosphere was sensational - I wish we had that every week", Canaries academy product Morris said.
