There is no scientifically proven connection between onions and any tooth related problem. While the odd old wives' tale may dictate this as an effective cure, there may not be any truth to this. Instead, there are several other and more effective methods that you could be employed in order to successfully get rid of toothache. One of the most significant ones is the use of cloves. Cloves themselves are excellent for toothaches. All you would have to do is press down a clove between the aching tooth and its partner. This will, after a while, dampen the clove sufficiently for it to release its juices and seep into your aching tooth, which will help to ease the pain. Another excellent alternative is to use a drop of clove oil and apply it to your aching tooth. This can be done by putting the single drop on a tightly wadded cotton ball and clamping it between two teeth. The idea is the same - for the clove oil to reach down to the root of the tooth. Cloves are the most powerful remedial measure to help with tooth problems of all kinds.
It is also a good idea to show a recurring toothache to a dentist before it worsens into something that may require removal of the tooth. This is not as impossible as you would think, and regular and good care of teeth is an important step in preventing this. Apart from using cloves, it is also a good idea to regularly rinse out your mouth with warm water to which a few drops of any antiseptic liquid have been added. Generic hydrogen peroxide would work best for this purpose. This would not only help by killing surface bacteria, it will also help by sanitizing your mouth. When it comes to teeth and connected problems, keep in mind that cleanliness is extremely important. If possible, keep sipping cold green tea as well. This is also known to provide relief in the case of badly aching teeth. If the pain is closer to being unbearable, you may be able to find relief by keeping ice in the mouth. This will help with numbing the surface area that is exposed to the cold. But this may not help if you have a problem that goes down to the root of the tooth. A warm compress on the face can help if there is any facial swelling.
