Hard palate) top of mouth towards the teeth it's milky white? is that serious or normal? very very worried.

Likely normal: The color in this area varies based on such things as thickness of tissue, blood supply, presence of a maxillary torus ( benign bony bump) , and natural tissue tone and color. Check your lighting when looking at this and look at someone else's with the same lighting to compare -- they may be different, or nearly the same. If unsure, see your Dentist for a check-up. Good Luck.

Not normal.: Pale is normal. Not milky white See dentist to make sure.
