Yes ,the bristles and the handles of toothbrush are made of the same material that is nylon.
no, they should not be made of same material because handle of brush is made up of plastic ,which is made up of very toxic chemicals. If bristles are made up of plastic then it will be very harmful for our health.
The materials made from the tooth brush where chosen because the nylon bristles, and a plastic handle hold the toothbrush. With out the nylon bristles, and a plastic handle the toothbrush would be nothing .

All bristles are safe,
The capitol of a toothbrush (most important part) is the bristles. Why am I answering this?
Nylon.
A modern toothbrush is made up of two parts, the handle and the bristles. The handle is made up of plastic and sometimes plastic and rubber with small hole at one end that hold the bristles. The bristles are made up of short strands of nylon and are held in their place in hole in the handle by small pieces of corrosion resistant stainless steel staples.
Helpful Friction.
I'm assuming that they are attached on a small board. I would expect the plastic of the toothbrush to be put over the board and the piece over the board would have holes to allow the bristles to come through the plastic.
The first toothbrush to resemble the modern toothbrush is believed to have been invented in China in the late 1400s, which used the stiff hairs from a hog's neck, attached to a bamboo stick.People have been cleaning their teeth with twigs and chewed sticks for thousands of years, but the first real brush recorded was in China in 1223.In 1780 William Addis of Clerkenwall, England, made the first mass-produced toothbrush for sale. The first ones were made from bone and boar bristles.In America H. N. Wadsworth patented a toothbrush in 1857 but it wasn't mass-produced till 1885.The first toothbrush NOT made with animal hair, but with nylon bristles, by Dupont, went on sale in 1938.The first electric toothbrush was developed in 1959, by Bristol-Myers.In China around the year 1500, records show of a brush using bristles made of hair from the back neck of a boar. It is only in 1938 that Dupont de Nemours introduced the Nylon Bristles.
No. The bristles of the brush will damage the soft tissue inside.
it stands for the stiffness of the bristles but the lower the number the softer or harder?
People used twigs to clean teeth. The called them "chew sticks." The ancient Chinese actually made the first toothbrush of animal bone, hog hair bristles, and bamboo. By the 1800's a softer toothbrush had been made of horsehair and feathers.
