Can you find the cavity? The dental caries

[yungwunn911]

What is the yellow stuff in the tooth? And later, the red?

The yellow is so called softened dentin.

It is decalcified by bacterial acid and stained red by caries detector liquid, acid red.

The detector allow me to visually inspect the infected dentin.

Thanks.

No.

I could find it by a Xray.

Thanks for your comment.
