So often we hear about the negative effects salt has on our bodies -- its role in raising blood pressure, for instance. However, the mineral compound has many healing properties as well. One helpful benefit of salt is that it can help ease a toothache.
Preparing this treatment is easy: Just pull out your salt container, measuring spoons and measuring cup from your kitchen cabinets; add 2 to 3 teaspoons of salt to a drinking glass; and then pour in one cup of warm water [source: Consumer Guide]. You can then mix the combination with a spoon and take a gulp of it. Don't swallow the salt water; you should swish it around your mouth like mouthwash. Once you spit it out into the sink, take another sip and swish some more.
Our last home remedy may not be quite as simple and inexpensive as a salt-water solution, but it is one of the most effective and recommended means of treating dental pain.
