Thanks for the query.
is a extremely painful complication seen 3-4 days after wisdom tooth extraction
There are following causes of dry socket after tooth extraction-
2. Rinsing and spitting a lot or drinking through a straw.
A dark blood clot at the site of extraction indicates healing.It should not be removed from its place.
If the extraction site will look dry and have just whitish bone,it indicates dry socket.
Pain will start after 2-3 days of extraction.
In case of dry socket you can feel bad breath
So would suggest you follow your prescribed antibiotics and analgesics course for 5 days,because it will prevent infection at the site of extraction and will be helpful in healing process.
If you feel,you having above symptoms of dry socket after 2 days of extraction,you need to visit your dentist
Nothing to get worried.
Hope this answered your query.
