Kerry...for what it is worth, medicine or not....cost of drugs not even considered, I would not take the chance. Bad teeth that have to wait until you can get funds for extractions will not kill him, but a platelet issue could. Worse case, if one of those teeth gets infected in the meantime, a round of clyndamiacin does wonders and it is not hugely expensive. EZs teeth need to all come out....half were removed five years ago...but he is too old and has a major heart murmur. We treat as needed. I realize he is older than Sagan so you may not want to ride those teeth out for a lifetime, but the risks seem too high.
Of course, you know my history....so my fears may be a bit extreme....but it just my perspective.
