There are two issues, both when white Phosphorus is ignited. One is that it burns so incredibly brightly, that it can damage eyesight if you're not careful. Secondly, the reaction cannot be quenched by water, meaning extreme danger if it makes contact with your skin.
White phosphorus is very dangerous and not just because it is poisonous. Red phosphorus is considered less poisonous.
Phosphorus is a non metal element. Atomic mass of it is 31.
The oxidation number of phosphorus in white phosphorus is 0.
Phosphorus is an element that has a red and white form. The red form is known as red phosphorus, while the white form is known as white phosphorus.
White phosphorus is very flammable.
No, it is extremely dangerous to store white phosphorus in the mouth. White phosphorus can ignite spontaneously in contact with air and can cause severe burns or even be fatal if ingested or inhaled. It should never be used in magic shows as a fire-producing effect.
As compared to white phosphorus, it is not so dangerous, as it is not poisonous and it does ignite spontaneously in air, if temperature is below 260 ºC. So, it is relatively stable and less reactive than white phosphorus.

Phosphorus has four allotropes which have remarkably different properties. White, Red, Yellow, and Violet. It is the origin word for phosphorescence. All in all a fascinating, and dangerous element, and quite essential for life.
Phosphorus is toxic. It can be acutely toxic in larger quantities, and can cause a gruesome condition called "phossy jaw" in lower doses. Phosphorus is also pyrophoric, meaning it will spontaneously ignite in air. The oxide formed from burning phosphorus is also toxic.
Unless you are a scientist working on weapons, nowhere. White phosphorus is very dangerous and deadly, so any possession of it without a license is a crime. You can't get the license anyway unless you are a weaponist.
I believe the most common type of phosphorus is white phosphorus's, which is known for glowing in the dark.
