Any health food enthusiast will be able to tell you the benefits of tea tree oil as a natural antiseptic. The smell of it alone implies clean. However, how well does tea tree oil work to alleviate the pain of a toothache?
Prevention
Consider the antiseptic properties of tea tree oil. Tea tree oil on your toothbrush once or twice a week will help kill the harmful bacteria that roam in your mouth that could lead to a toothache in the future.
Treatment
Some home remedies actually suggest using a cotton swab to apply the tea tree oil to the affected tooth. It will taste horrible, but the effect should be felt relatively quickly.
Toothbrush
To give your toothbrush a good cleaning between brushes, put a few drops of tea tree oil on 1 to 2 times a week. This will kill any lingering bacteria you've cleaned out of your mouth previously. This is also good if you are sick and you don't want to change your toothbrush.
Other Properties
As well as an antiseptic and an analgesic, tea tree oil is noted as a cicatrizant. This means it also heals wounds, so if there are cuts in your mouth from a broken tooth, the tea tree oil will help to heal the damaged area.
Alternatives
Some remedies suggest adding a few drops of tea tree oil to 1/2 tsp. of aloe vera and applying it to the affected tooth. For more cleaning power, try adding the tea tree oil to baking soda when you brush. The abrasiveness of the baking soda will combine with the antiseptic tea tree oil. It will taste horrible, but you will have a clean mouth.
