To temporarily relieve tooth pain, apply an over-the-counter numbing gel that is recommended for tooth pain, or apply two drops of clove oil to a cotton ball, and place the cotton ball between the cheek and gums in the affected area of the mouth. If clove oil isn't available, chew a whole clove, or place a small pinch of powdered clove between the cheek and gums in the affected area.
Alternatively, dissolve 1 teaspoon of salt in a cup of boiling water. When the water is warm, swish the salt water around in your mouth for 30 seconds. Spit the salt water out, and repeat the swishing process as often as needed.
If the pain is accompanied by a bad taste in the mouth, swish hydrogen peroxide around in the mouth to help remove some bacteria. Pain, swelling, fever and a bad taste may indicate an infection, for which you should see a dentist.
Another option is to apply an ice pack to the cheek over the affected tooth for 15 minutes, or place a small piece of ice directly onto the tooth to numb the nerves causing the pain. Over-the-counter pain medications, such as ibuprofen, also temporarily relieve tooth pain. See a dentist if the pain persists for longer than one or two days.
