Incisors filled, can you see?

If the tooth decay occurs on the labial side, that is, on the side we can see, then we still need to remove the caries from the labial side for filling, so it is easy to show that the edge can be seen, especially if the color is not beautiful. If the tooth decay of the incisors occurs on the lingual side, that is, the inner side that we can not see relatively, then the filling is invisible. If the teeth are filled with a better, more beautiful resin material, and the teeth are polished after filling, then whether it is the labial side or the lingual side, the teeth are not visible after filling.
