Sir, in response to the letter by M. Lynch: World's worst teeth (BDJ 2007; 203: 62), I beg to disagree with his/her statement that the Filipino population have the worst teeth in the world. Dr Lynch stated in the letter that s/he only travelled to the island of Mindoro and got the chance to treat the oral health problems of the Mangyans. The Mangyans are one of the remaining tribal groups in the Philippines and they only represent a very negligible percentage of the general Filipino population. Although the Filipinos were thankful for Dr Lynch's effort to improve the oral health of the village, s/he would have been wrong in generalising that Filipinos have the worst teeth in the world. Has Dr Lynch travelled to all parts of the Philippine archipelago or indeed to all parts of the world to justify this assertion?
