For how long should i have a swollen cheek, pain after teeth removal?

For 10 days: It take about 1 week to ten days.

1-4 weeks: Normally, any cheek swelling will take 7-10 days to return to normal. Unfortunately, the mouth has some very nasty bacteria present that occasionally invade the extraction site and cause a more severe infection that may delay the normal course of healing.

7-10 days: 7-10 days at most. If persisting longer than this, ask to see an oral surgeon.
