If you are having sedation you will not be able to drive, possibly for 24hrs after extraction. Check with your dentist.
After the extraction try not to eat until the anaesthetic has worn off. The local anaesthetic used for lower molars will numb up almost half your mouth including half your tongue so you can do a lot of damage chewing if it’s all numb.
Nothing too hot or too cold for first 24hrs and don’t start using salt water mouth wash until the following day. Also DON’T SWISH AROUND. It can loosen the clot leading to early loss and a dry socket. Just take a mouth full and hold it around the socket. Spit out and repeat a few times. The water should be as hot as you can stand it.
Make sure you have painkillers, paracetamol is usually sufficient.
If it starts to bleed use clean rolled up wad of gauze/tissue, dampen it slightly the psh hard down onto the bleeding socket continuously for 15mins. Don’t dab it or keep checking it because you will pull out the fresh clot. Use salt water after meals and before you go to bed after brushing teeth.
The pain will gradually improve but if it starts to get worse ( severe pain that doesn’t respond to painkillers) get in touch with your dentist. It may need a dressing placed.
It will look pretty grim after two days but as long as it is not painful this is normal. The clot, as it starts to organise goes a whity/yellowy colour and a bit moth eaten in appearance.
Brush normally but carefully around the socket. Don’t rinse after brushing just spit out the excess.
Finally find an old towel to protect your pillow. And prop yourself up to sleep b cause your blood pressure increases in your head when you lie down and can cause the socket to start bleeding again.
