Filling instead of scheduled extraction

So the first extraction in my orthodontic agenda took place about a week ago. I was scheduled to go through the second extraction this week. But my dentist denied the condition of my post-extraction effects.


As I was asked to quicken up the healing process after my first extraction, I was suggested to:

• eat soft food for the first few days to go easy on the wound
• eat cold ice cream to heal the wound quickly
• rinse my mouth with lukewarm salt water regularly from the following day to prevent any infection from developing around the wound

I was not doing the last one and my dentist said "No" to extracting anything this week after seeing the infection building up around the wound. 

We rather went ahead with a pending filling that i needed on one of my tooth instead of the scheduled extraction.
