A false tooth assembly for a generator stator core is presented. The false tooth assembly has a tapered shape including multiple tapered false tooth pieces. The multiple tapered false tooth pieces are installed into a damaged area in a tooth of a lamination of the stator core such that a wide end of the false tooth assembly is disposed into a wide opening of the damaged area and a narrow end of the false tooth assembly is flushed with a narrow opening of the damaged area at a tip of the tooth. The tapered shape of the false tooth assembly enables the false tooth assembly to fill the entire damaged area and to lock the false tooth assembly into the damaged area. The false tooth assembly can be used to repair stator core in any region of the stator core including step iron region without being dislodged during generator operation.
