There is a lot of talk in the news, etc., about Metzitzah B'peh that employs direct oral contact being dangerous.
First: If it is dangerous, shouldn't pikuach nefesh push it off?
Second: How important is it to a Bris in the first place?

The gemara strongly implies that metzitzah is done for health reasons. Nowadays, we can follow that tradition safely by doing it with a tube. It seems ironic to to follow the gemara's health-suggestions in a way (b'peh) that we know to cause health-risks. However, some groups feel that there are other reasons for doing Metzitzah and that it should still be done since the health risks are small. If so, they should make strong safeguards to lessen the risk of transmitting disease.
Hakirah has an article from 2006 available online about metzitzah b’peh (pdf), which I summarize below (from my previous summary).
In the article he explains the historical medical background to metzitzah. In ancient times, people didn't know that blood circulated or that pathoegns cause disease. The hellenic system of medicine thought blood was attracted to cuts and could decay and form pus, so it was necessary to get the blood to flow from a cut to prevent disease. (The author cites R’ Nachum Rabinovitch who compares the Rambam’s requirement for metzitzah to the Rambam’s suggestion to suck the blood out after a snake bite). He discusses some modern-day rationals for doing MBP, but then refutes them.
The next part shows that metzitzah b’peh is a danger and many cases are cited where it has unfortunately caused harm to infants. He also tells the the history of MBP, and quotes some of the discussions about it from the 19th century. He then discusses the p’sak of the chasam sofer who didn’t even consider metzitzah b’peh to be a minhag. He concludes that if most of the litvishe gedolim accepted that MBP was a danger, surely now, when we know much more about transmission of diseases, we should not risk it.
Back in September (2012) there was well written article by Rabbi Moshe Zuriel (from Bnei Brak) posted on the Parsha Blog about this topic. Much of the mareh makomos that are brought in the article have already been mentioned here. However I'd like to contribute the article as it answers the question and I find it to be well-written and posing very good points
