We demonstrate the early diagnosis of cracked tooth syndrome (CTS) by imaging the microcracks on a tooth in the closed mouth condition using a mechanoluminescence (ML) phosphor and a stretchable and self-healable photodetector array that can conformably cover a single tooth. This method does not require sophisticated equipment and hence will be useful in the early diagnosis of CTS. To the best of our knowledge, this is the first report on the use of ML for the detection of the position of tooth cracks.
