It depend on what type of Snail it is because most snail produce their own shells, so the type of snail matters because some snails grow shells quicker than others and have a chance of surviving than the ones that can't grow their shell as quick.
The umbo, also known as the beak, is the oldest part of a clam shell. It is the point where growth starts and forms the center of the shell. Over time, new layers of shell material are added, extending outwards from the umbo.
Yes! The shell of a snail is just like our spine. Its true- do not try and remove at anything- the snail would die a slow and painful death!

yes a baby snail will die if it's shell is chipped because a snail shell is very delicate and so is the snail.
No; the shell grows as part of the snail.
when a snail is born it has a shell, and its actual body is still growing in the shell.
The oldest part of the clam shell is called the umbo. It is the portion closest to the hinge and is found by following the growth rings to their center.
The snail's shell will get writing on it. What do you think.
It is secreted by a portion of the snail body called the mantle.
The umbo which is located at the anterior end of the clam
Note: I copied this answer directly from: http://rochester.kidsoutandabout.com/main-columns/nature/snailshells.html Snails are hatched from eggs. When they hatch, they eat most of the shell, but a small part of it stays with them and that is the beginning of their shell. As the snail grows, so does its shell -- in a spiral shape. New shell is added at the opening of the shell. In the center of the spiral is the part of the shell that the snail began life with. The shell is made from several layers. The thin outer layer is made from an organic substance known as conchiolin. The thicker layer underneath is formed from three layers of crystalline calcium carbonate, similar to the chicken egg of which you may be more familiar. The color of the shell depends on the types of food the snail is eating and also the type of snail.
