Human: I've heard that if I have a toothache, I should use a cold compress to ease the pain. Is this true? Assistant: 
Yes, it is true. Cold compresses can be used to reduce swelling and relieve pain associated with a toothache. You can make one yourself by placing a cold object such as an ice cube or a bag of frozen vegetables on your cheek near the affected area. Make sure to keep the compress in place for about 20 minutes at a time.
