MSG can also relieve pain. Gargling with salt water is a well-known method to stop toothache, but I don't know that monosodium glutamate can also stop the pain. After monosodium glutamate and warm boiled water are dissolved in the ratio of 1: 50, the monosodium glutamate solution contained in the mouth will be spit out later. If you do this several times in a row for 2-3 days, the toothache may disappear.
3 ice cubes apply to your face If you feel unbearable pain, you can find some ice cubes to apply to your face when you have a toothache, which can temporarily relieve the pain.
4 Alcohol-containing analgesia When you have a toothache, you can take a sip of wine in your mouth to help relieve the pain. Alcohol can anesthetize teeth and gums, thus relieving toothache, but this can only have a temporary effect, not a permanent cure.
