The spelling of the word "auditory teeth" seems unusual at first glance. However, if we break it down using the International Phonetic Alphabet (IPA), it becomes clearer. "Auditory" is spelled with the sounds /ˈɔːdɪtəri/, while "teeth" is spelled with the sounds /tiːθ/. It is likely that the two words were combined due to their use in dental medicine, where auditory feedback is often used to ensure correct tooth placement. Despite its odd appearance, the spelling of "auditory teeth" accurately reflects its pronunciation.
