The skin is always shedding and has to be constantly replaced from lower layers. The teeth are not being replaced. They are eroded and not rebuilt as we age.
An adult persons teeth

Mitosis occurs in somatic cells. The main purpose of mitosis is to create two identical cells from one single cell.
Mitosis is the process that produces new 2N cells from 2N cells Meiosis is the process that produces 1N reproductive cells.
Most Neurons, and Epithelial cells surrounding the egg.
After mitosis you have two cells and after meiosis you have 4 cells.
Skın cells
No, not all cells are capable of mitotic division in an adult. Certain types of cells, called permanent cells (eg. heart muscle cells and brain cells) can not undergo mitosis in an adult. Another type of cell that cannot undergo mitosis is the mammalian red blood cell - which has no nucleus so cannot divide.
These are called permeant cells. Examples are adult neurons, striated muscles, cardiac muscle, RBCs and cells of lens in the eye.

Mitosis
Somatic cells or body cells perform mitosis.
Mitosis occurs in somatic cells. The main purpose of mitosis is to create two identical cells from one single cell.

2 cells are formed after mitosis.
