Five teeth out of 32 seems enough for everyone in this murder conviction in the UK. The dentist looks satisfied on the video. (the 3rd video in the article). Problems about expert error rates, etc., always go out the window when police run the news show.

It is striking that a country which introduced DNA profiling to the world, would go back to 1970’s bitemark techniques that have been instrumental in dozens of wrongful convictions.
