Space is cold - colder than you can possibly imagine. Their spaceship is in no danger of melting in space. The danger arises when they re-enter the earth's atmosphere. Then they need either a heat-shield or, on the space shuttle, special tiles which are heat-resistant.
Astronauts on space missions use special heating systems in their spacesuits to regulate their temperature. These systems can generate heat to keep astronauts warm in the cold vacuum of space. Additionally, the spacesuits themselves are insulated to retain body heat and prevent it from escaping into space.
Space suits: to protect astronauts from extreme temperatures, micrometeoroids, and provide oxygen. Extravehicular Mobility Units (EMUs): for spacewalks to enable astronauts to move and work outside the spacecraft. Tether systems: to keep astronauts connected to the spacecraft while working in space.
Astronauts on the space station have a controlled climate with heating systems to regulate temperature. They also wear special clothing that helps to maintain their body heat. Additionally, the station has insulation to minimize heat loss.
The term "artificial gravity" refers to using science technology to create gravity. This is usually desired by astronauts and space organizations such as NASA to keep their astronauts healthy and to minimize the effects of weightlessness on astronauts during long term space travel.
Astronauts in space rockets typically sleep in designated sleeping quarters that are usually small, private sleep pods or sleeping bags attached to a wall. These sleeping areas are specially designed with restraints to keep astronauts in place during sleep in the microgravity environment of space.
No the astronauts wear their space suits when they are launched, but they remove them later.
what astronauts do to keep their mouth healthy is to brush their teeth obviously (and what do suits have to do with your mouth) NOTHING!
The answer is an umbilical cord. It keeps astronauts from floating out into the universe.

gravity and oxygen
No. One of the main reasons that space ships are not equipped with gravitational shields is the fact that such a device doesn't exist. What would a gravitational shield do?? Keep gravity in? Keep it out? Set up a barrier between astronauts so that they don't accidentally get attracted to each other and bang together while they're asleep?
There's no gravity in space - this affects their muscles. Exercising keep the muscles toned.

Tether systems: to keep astronauts connected to the spacecraft while working in space.
The spacecraft that astronauts go up in, have their own life support systems which regulate conditions to keep the spacecraft hospitable.
The astronauts wear tethers whenever they exit the space station so that they remain attached to the station. Otherwise, without sufficient gravity to keep them close by, they could easily drift away into space.
To provide a pressurized environment and oxygen to keep the astronauts alive, as well as regulating temperature.
