“…Tonsilloliths may develop from a collection of desquamated epithelium, serum, food debris, and fungal and bacterial colonies. 1,3,8-11 Tonsilloliths appear to have characteristics in common with biofilms, 1 and tonsillolith calcification may occur over time from the deposition of inorganic salts, progressing from soft gels to hard “stones.” 10,12,13 The composition of the bacterial flora in tonsilloliths is diverse and has included normal mouth flora, such as Actinomyces , and volatile sulfur-producing anaerobes, such as Eubacterium, Fusobacterium, Megasphaera, Porphyromonas, Prevotella, Selenomonas , and Tannerella . 3,14 Several investigators have identified specific correlations between Actinomyces and tonsilloliths.…”
