Mouth microbiome samples were self-collected, mechanically lysed, DNA purified, amplified with barcoded 16S V4 primers, pooled, size-selected, and sequenced on Illumina NextSeq 500 (2150 bp). Reads were demultiplexed, quality filtered, clustered, and taxonomically assigned using the SILVA database.
