Daniel Flynn was passed fit to play in New Zealand's tour match against Northamptonshire.
The left-handed batsman was hit in the teeth by a bouncer from England fast bowler James Anderson that went through his helmet grille during the second Test at Old Trafford.
Flynn played no further part in the match after the incident on the first afternoon as the Black Caps slipped to a six-wicket defeat.
He lost two teeth, has had one replaced, and made his most recent trip to the dentist's, to remove a nerve, on Thursday.
But the 23-year-old returned for the tourists' three-day match at Wantage Road and - provided he comes through unscathed - is likely to retain his place for the third and final Test, which starts at Trent Bridge on June 5.
