Tooth Pain

• Place a cold compress against the side of your cheek that contains the aching tooth for 20 minutes to numb the pain. If your toothache is a result of a pulled tooth or dental work, you may also want to use the cold compress on your jaw to help relieve the pain and swelling.
  
  

Bites

• Apply a cold compress to bug or animal bites on your skin to reduce swelling and itching. If blood was drawn, bandage the area first and then apply the cold compress on top of the bandage.
  
  

Headache

• Set a cold compress on the area of your head where you are experiencing a headache. The coldness will cause the nerve endings to become less sensitive, which reduces the amount of pain you feel. Leave the cold compress on for 20 minutes and then take it off for 20 minutes. Reapply as needed.
  
  

Bruises

• Lay a cold compress over your bruise as soon as you notice one appearing, as it will limit or reduce the size of the black and blue mark if you use it right away. It will also numb the pain and reduce swelling. Use the cold compress for 20 minutes and then give yourself a 20-minute break. Repeat as needed.
  
  

Swelling Resulting from a Surgery or an Injury

• After surgery or a major injury your doctor may instruct you to use a cold compress for anywhere between 48 and 72 hours, taking a break every four hours. The cold compress should always go on top of any bandages. This will reduce pain and swelling and reduce the length of your recovery.
