If you have surface scratches on your enamel that can only be seen when the teeth are dry, is that serious? I realize you'd need to identify the cause and stop further damage. But can the teeth stay healthy without restorations with surface scratches?
okay, so if you have not had any trauma to the said tooth, you are probably noticing craze. This is the wear and tear on the enamel that is nothing to worry about. If there is no pain, it is just craze
