you can file, cut or clip them off. Just make sure there is a bit of your tip showing so your undernails won't bleed. So, just like if you had a bruise on your leg, it'll go away eventually if you leave it alone.Eat/drink Calcium fortified food and drinks.They appear when you haven't eaten enough fruit hope it helps!
Put a warm cloth on your fingernails, for about five minutes. Soak them in nail polish remover. Then take a nail file and file until your down to the second knuckle. I guarantee the white spots won't be there anymore
