Translation:I brush my teeth every day.
Can we like, verify if 歯 is at least JLPT level N3? Because if it is, then there's no reason not to use the kanji for it. Very confusing, especially that I don't use TTS that often. Or even punctuation. A comma would do.
My problem is coming from doing the timed practice but analyzing this question took me 10 seconds.
The entire course should, really, consider the kanji difficulty levels. How about introducing them by grade level in which they are taught?
