Consult a dentist a this could be caused by too thin enamel coating or intake of excessive fluoride.

White "marks" can be caused by decalcification. Since you just noticed them, I assume they have recently formed and not an enamel defect. Your dentist can confirm what they are and prescribe products that can recalcify those areas.
