You're well on your way to a bacteria-free mouth, and this last teeth-cleaning practice is easy. It's just swish and spit, but it's also very important. After brushing and flossing, rinse your mouth with an antibacterial mouthwash, which helps destroy bacteria that cause plaque and gingivitis. In a six-month clinical trial, rinsing with mouthwash that contains essential oils (such as Listerine Antiseptic or Dr. Tichenor's) reduced the buildup between dentist visits [source: Charles, et al]. These essential oils slip between teeth to kill bacteria that evade your toothbrush and flossing routine. The same study also showed that mouthwash with chlorhexidine had antiplaque and antigingivitis activity, but it can stain teeth.
If you have trouble getting floss between your teeth, mouthwash is an effective runner-up method of removing bacteria -- but flossing and mouthwash work best when they work together.
With your sink routine down, you can start practicing these next remedies that help combat gingivitis.
