After going to the bathroom to clean my teeth; for a split moment; I forgot to put my mask back on.  I realized it quickly and put it back.  I don't think anybody realized it as most passengers were resting. It was a human mistake and I corrected it right away. It was a moment of forgetfulness.
Flight Attendant reported briefly forgetting to put the face mask back on after departing the lavatory.
