Just beyond the decay. A dentist removes the decay and then fills. so it depends on how deep the decay is. Yes, just beyond the decay. So it depends on how deep the decay/cavity is. If the decay is too deep and goes all the way to the center or Pulp Chamber (nerve) then usually a root canal will be necessary. Once a root canal has been done the tooth is more fragile and probably needs a crown to hold it together (expensive)....especially if it is a back tooth because the back teeth bear the most burden and chewing force, they often need to be reinforced with a crown after a root canal. Moral of the story? Get your teeth checked regularly so that you can fix cavities with small fillings before any of this root canal business will be necessary. And don't forget to floss because most decay happens in between the back teeth.
Well it normally depends on how deep in the ocean you go,

Traditional fillings are a mercury/silver mixture. These are the fillings everyone is used to seeing. On average these fillings will last 10-15 years in an adult, but they can fall out, and need to be replaced. Resin fillings are coloured to match your tooth, and have half the life-span of traditional fillings, however more people are opting to go with this type of filling for both cosmetic and health reasons, over recent concerns about mercury content in traditional silver fillings.
One possible method is to use a magnet to separate the iron fillings from the sulfur sand. The magnet will attract the iron fillings, leaving behind the sulfur sand. Alternatively, the mixture can be treated with a solvent that dissolves the sulfur sand, allowing it to be separated from the iron fillings by filtration.
Because there are much better salt water fish out deeper in the ocean. You would normally go about 40 miles out
Hope it has to be FILINGS and not FILLINGS.
donut fillings

To separate sawdust and iron fillings, you can use a magnet to attract and separate the iron fillings from the sawdust. The iron fillings will be drawn towards the magnet, allowing you to easily separate them from the sawdust.
Iron fillings are easily sedimented in water.
