Liquid nitrogen is very cheap because it is a by-product of the production of liquid oxygen. Nitrogen is obtained from liquid air by distillation at -196Â°C. The gas obtained by this process is actually a mixture of nitrogen and about 1.25% noble (or inert) gases, argon, neon, krypton, and xenon.

1 Traditional metal braces can cost $1,500 -$10,000 or more depending on the severity of the bite and positioning problems that need to be fixed, the length of time the braces will be in place and whether the braces are on one set of teeth or both (upper and lower). Expect to pay $3,000 -$8,000 or an average of $5,000 for Damon braces, an alternative teeth straightening system that uses a series of computer-fabricated clear plastic aligner trays that cover the teeth; the patient switches to a new tray about every two weeks.
