I have a white bump on my gums should i be worried it doesn't hurt at all?

No reason to worry: I'd recommend using BreathRx or some other mouth wash in the morning and before bed until it goes away completely. Importantly - don't eat/drink anything except water after using the mouthwash at night as you don't want more food decaying in your mouth while you sleep.

Needs to be seen!: We can't properly diagnose these types of situations, sight unseen, over the internet. It may or may not be normal and you should see a dentist to have it evaluated. Can YOU tell if the dark spot on my skin is an age spot, freckle, blood clot, mole or melanoma?
