An infection in your tooth can be cured at home only if it is extremely mild and you have managed to catch it before such time as it spreads about nastily. If it is a deep rooted infection that has been around and neglected for a few days, you can forget about taking care of it by yourself at home. You would need to consult with a dentist who would in all probability prescribe a course of antibiotics to take care of this situation. Please do this, as a neglected infection could actually end up in you losing the tooth as well. And do keep in mind that it is not possible to kill a bacterial or a viral infection without the use of antibiotics. Once you have killed the living infected materials in your mouth, you can go ahead and clean up the rest of the infection using remedial measures at home. To start with, take a cup of comfortably hot water and add a few drops of hydrogen peroxide to it. Instead of hydrogen peroxide, you can also add a few drops of any antiseptic liquid to this water. You can use this water to swish about in your mouth and spit it out. Please do not swallow. You need to do this a few times after each meal and also every other hour, if your meals are not as frequent.
Once your mouth has been cleansed in this way, you can take a whole clove and clamp it down on your infected tooth. Cloves are very helpful in clearing up any infection you may be suffering from. The clove being there constantly will ensure that there is a steady supply of clove oil going slowly down the shaft of your tooth. This will not only help with the healing process, it will also provide relief. But you have to be a little patient to clear it. It is possible that this may take about a day or two to actually start showing effects. You can also use a drop of garlic juice on the infected tooth every four hours. This will also help by not allowing the infection to spread. Garlic juice can also kill certain infections quite effectively. Another effective cure for getting most of the fluids out of the tooth is to press a wet and cold tea bag against it and leave it for a while.
