Honestly, I do not think swimming water will affect your mouth if you have had teeth pulled out, so straight away!
yes you can drink milk after having a tooth pulled
I do not recommend swimming in a pool water for at least 5 days and not swimming in lake water for at least 7 days following extractions. It is the same if you have a deep wound elsewhere on your body.
Getting a tooth pulled is like getting a shot.
I never waited
usually after 30 minutes
yes you can
No, having migraines for 5 days in a row is not normal at all after having your wisdom teeth pulled. You should contact the dentist right away.
The chlorine floater should be pulled from the pool and set to one side where it will not be tampered with. Then remember to return it to the pool when you are finished swimming.
