Antibiotics cannot cure a root canal infection because the source of the infection is inside the tooth where there is no blood supply; without blood supply there is no mechanism to deliver antibiotics. The cure is the complete shaping, cleaning and obturation (sealing) of the contaminated root canal space.
Thanks for the A2A, Joseph Boyle. You've already gotten plenty of answers, but since they differ a bit, I may as well cast my vote. According to http://Space.com The minimum distance from the Earth to Mars is about 54.6 million kilometers. The farthest apart they can be is about 401 million km.
Mars is much farther from the sun than Earth â about 142 million miles vs. our 93 million miles. Earth days and Mars days are nearly equal â one Martian sol is about 24Â½ hours. It takes about 687 days for Mars to revolve around the sun.
