How To Reduce Swelling After Tooth Extraction?
Use Cold Compress
Applying an ice pack after a tooth extraction is the most common practice to reduce swelling and pain. 
However, ice packs are only effective for the first few hours.
Take Pain Medication
You can take OTC pain medication to reduce pain and swelling after tooth extraction. 
Paracetamol and ibuprofen are commonly used painkillers, especially after wisdom tooth extraction. 
Keep Your Head Elevated
When recovering after dental surgery, do not lie flat on your back. Sit up or recline during the day. And, use pillows during the night to elevate your head.
Swelling of the face can be reduced, and adequate blood flow can be aided by keeping your head above your heart. This can help deal with the swelling. 
Apply Warm Compress
You can apply a warm compress after 2-3 days have passed. Do this for 20 minutes on and 20 minutes off to help soothe the affected areas. 
Rinse With Salt Water
Saltwater rinses can help get rid of harmful bacteria and swelling. You can try this after a day has passed after your treatment. 
Mix a teaspoon of salt in warm water and hold it for around 30 seconds. Moreover, salt water rinses also help with dry sockets.
