I'm having a colonoscopy on october 24th. i need two teeth to be extracted. can i have them extracted at least two weeks before colonoscopy? is it enough time to heal?

It's advisable to wait until the extraction sites are fully healed before a colonoscopy. Traces of occult blood could be in stool for some days after the extractions. Avoid complications and confusion by asking your oral surgeon and the gastroenterologist what their preferences are.

This shouldn't be a problem at all. You could safely do the two procedures within a day or two of each other.

Have them extracted as soon as possible, so no concerns will arise. If the extractions are done two weeks before your procedure and are not difficult, and you have no medical issues, you should be fine. Either way consult both doctors.
