post crown; dowel crown; false tooth
Dental term for an artificial tooth fixed onto a post inserted into the root. In everyday conversation, 差し歯 is the common word for this type of dental prosthesis.
tooth of a geta clog
Refers to the raised wooden supports on the sole of traditional Japanese geta sandals. This sense is less common in daily life but appears in contexts discussing footwear.
The teeth of my geta clogs have worn down.
My front tooth broke, so I had it replaced with a post crown.
My false tooth came off; I have to go to the dentist.
Standard spelling for both senses.
Variant without okurigana; less common but still seen.
Compound of 差し (sashi, 'inserting') + 歯 (ha, 'tooth'), with rendaku voicing to ば. The dental sense is a straightforward extension of 'inserted tooth', while the geta sense likens the wooden supports to teeth.
