Is mouthwash really necessary?
There are mint, lemon and salt, ginger, and many more types of mouthwash flavors, but are they really necessary in your daily oral hygiene schedule? Many people enjoy using mouthwash because of the fresh taste it leaves in their mouths, but what exactly does it aid? 
Most mouthwash brands only aid people with fresh breath, which is what its primary use is. Some are made to help target the bacteria that cause gingivitis or periodontal disease. This does not cure the conditions, though.
Mouthwash does not penetrate very deep below the gum tissue to clean or remove any bacteria that may cause oral discomfort. Using a mouthwash does not take the place of optimal brushing and flossing. While it may offer additional benefit in terms of reducing the risk of bad breath, cavities, or gum disease; or for relief of dry mouth or pain from oral sore In the dental world, brushing and flossing is critical to the best oral health for everyone! Brushing and flossing are more beneficial for the overall oral health, but mouthwash will always be there to provide fresh breath and to help rid bacteria on the most outer surfaces.
