Nobody knows for sure. We dont even know exactly how many species there are, let alone how to count them or how fast they grow. Estimates of the number of bacterial species in the oral cavity vary between 500 to 650 different species. They live on the teeth and tongue, of course, but biofilms also cover the cheeks and oral mucosa.
If these possible clades, candidate phyla, are included, the number of phyla is 52 or higher. Therefore, the number of major phyla has increased from 12 identifiable lineages in 1987, to 30 in 2014, or over 50 including candidate phyla. The total number has been estimated to exceed 1,000 bacterial phyla.
