Zebrafish (Danio rerio) are a popular model organism for scientific research, due to its small size, rapid development, and transparent embryos. One of the areas of study involving zebrafish is their teeth, which are continuously replaced throughout their lives. They have two types of teeth: incisors and pharyngeal teeth, compared to humans, who have only one type. Zebrafish teeth are replaced continuously throughout life, a process known as polyphyodonty, in contrast to humans, who are diphyodont and replace their teeth only once. Zebrafish teeth have been the subject of numerous experiments, including studies of tooth development, regeneration and evolution. In conclusion, zebrafish teeth are a fascinating subject of study in scientific research. In this review, we will describe zebrafish teeth, the experiments performed on them, and provide a comparative analysis with human teeth.
