It depends on your tolerance to pain. Even if your cavity is small, if the drill or polisher gets near the nerve, its going to send shocking pain. I had a very deep cavity that I had filled and had mistakenly taken quite a bit of Vitamin C before the procedure. Vitamin C will prevent Novocaine from working. It was very painful, but at my threshold.
On the other hand, Novocaine is pretty shocking to the body and to the immune system itself. If you're thinking of forgoing it for health reasons, and the cavity is small, it might be worth it to give it a try. You can always ask for Novocaine halfway through if you need it.
A thread chaser is used to clean the thread marks in a drilled hole or bolt cavity. It should be used with a lubricant to make sure the threads are smooth and clean, before restoring the rest of the pieces.
Toothache

The bodies decomposing left a small cavity surrounding the remains. The ash hardened leaving a mold of the person containing just the bones. They located the cavity, drilled a small hole, filled the hole with plaster, then removed the plaster cast containing the bones from the ash.
A dentist will inspect your teeth, and advise on whether any dental work is needed. A cavity will probably be drilled and then filled with a special dental paste. This will, hopefully, prevent the root/ nerve of the tooth from becoming infected, leading to a painful toothache.

The nasal cavity is part of the Olfactory System, which is one of the 5 senses and is the sense of smell. It works closely with our sense of taste. Another function of the nasal cavity is to warm and moisted the air as we breath in. That is why we are told that we should breath in through our noses and out through our mouths. On a very cold day, we may do this automatically without realising. Hope this helps.
The Thoracic Cavity
Only if it is painful to the child.
The dentist would inform me that I lost a tooth.
Yes you should worry somewhat. It is because cavities can cause problems in the teeth.
