We provide a formula for the number of $mathbb{F}_{p}$-points on the Dwork hypersurface $$x_1^n + x_2^n dots + x_n^n - n lambda , x_1 x_2 dots x_n=0$$ in terms of a $p$-adic hypergeometric function previously defined by the author. This formula holds in the general case, i.e for any $n, lambda in mathbb{F}_p^{*}$ and for all odd primes $p$, thus extending results of Goodson and Barman et al which hold in certain special cases.
