In general, people should use mouthwash two times per day: once in the morning and once in the evening after cleaning the teeth. However, if someone does not carry a toothbrush, toothpaste and floss around to clean teeth after each meal, rinsing with mouthwash is certainly better than doing nothing.
Although you can use mouthwash whenever you need to freshen your breath, the best time to use mouthwash is right after you eat.
Children under the age of 6 shouldn't use mouthwash, and kids over 6 should be supervised whenever they use mouthwash, according to the American Dental Association. If you have sores in your mouth, have a compromised immune system, or you're currently undergoing chemotherapy, you might want to avoid using mouthwash.
Mouthwash Is a Short-Term Fix
And if breath isn't fresh after a good brushing, it typically means it's packed full of bacteria. Mouthwash doesn't remove the sticky plaque and bacteria that only a good brushing and flossing can.
Mouthwash can be used every day if instructed by your dentist. However, make sure to also follow the instructions on your specific product, including how often to use it and how much to use.
A general rule of thumb for safe use is to limit the use of mouthwash to one time per day, in conjunction with brushing the teeth and flossing two to three times per day and visiting the dentist one to two times per year for routine oral health exams and screenings for oral cancers.
Mouthwash may actually cause more cavities
First of all, your oral microbiome exists to help support the natural remineralization of your teeth. If you kill all the bacteria in your mouth (both good and bad), you eliminate a critical part of the equation in reversing tooth decay.
Mouthwash is generally meant to be swished around in the mouth for 30 to 60 seconds. Make sure you follow the directions on your specific bottle. Swishing for less than 30 seconds isn't usually enough time for the mouthwash to be effective while swishing for longer than a minute won't give you any additional benefits.
If you brush your teeth well, twice a day, and floss daily, mouthwash is not strictly necessary. However, most dentists highly recommend adding mouthwash to your morning and evening routine.
“Unfortunately, mouthwash doesn't differentiate and kills all bacteria. As a result, mouthwash can cause harm in the long run because it can disrupt the microbiome and impede the normal functioning of your body.”
Short answer: It doesn't matter. However, if you are using a fluoride toothpaste, wait at least 30 minutes before you rinse (yes, even a fluoride one) as it'll wash away the fluoride from the toothpaste before it can do its job. If you do use a fluoride mouthwash, wait 30 minutes before you eat or drink.
It is not recommended to rinse your mouth with water after you have just used mouthwash. This is because many mouthwashes contain ingredients such as fluoride that need time to start working. If you rinse your mouth out straight after, the fluoride will also be washed away during the rinsing.
You can use mouthwash prior to brushing to remove any food debris and plaque build-up in your mouth to set yourself up for a good cleaning. One important thing to note is that if you're using fluoride toothpaste, don't use mouthwash for at least 30 minutes after brushing!
Can You Use Too Much Mouthwash? Using mouthwash several times a day for a long period of time may cause more harm than good, especially if you're using an alcohol-based brand. Alcohol can irritate the soft tissues of the mouth and may also cause dry mouth.

Overuse of mouthwash might disrupt your oral bacteria balance, causing more harm than benefit to your dental health. Do not keep using it if you see problems. If you see new mouth ulcers or stains on your teeth after using mouthwash, stop immediately and consult your dentist.
Can You Overuse Mouthwash? One of the main ingredients in mouthwash is alcohol. Alcohol destroys bacteria, but it can also cause harm to your gums, inner cheeks and tongue if over used. The alcohol itself has a drying property that will absorb the moisture from your mouth and cause the affected areas to dry out.
Mouthwash and Gum Disease
The fact that you keep the mouthwash in your mouth for as long as 60 seconds can cause problems. This process can introduce things to your mouth that can lead to gum disease or cancer. Alcohol-based mouthwash also limits the amount of saliva that the mouth produces.
Which mouthwash is safer for your teeth? Alcohol-free mouthwash is considered to be safer for your teeth because you do not have to worry about your enamel being weakened by the alcohol in your mouthwash or your gums burning while you rinse.
While it may be surprising, a study has found that flossing first followed by brushing with a fluoride toothpaste is more effective in removing interdental plaque than brushing first, flossing second. In addition, flossing before brushing results in greater fluoride retention between teeth.
Most Listerine products, a popular antiseptic mouthwash brand, cause a burning sensation. Listerine contains menthol, eucalyptol, thymol, methyl salicylate and alcohol. The first four ingredients are essential oils. It is the alcohol and the essential oils in the products that cause the burn.
Sadly, some mouthwashes may actually contribute to tooth staining and detract from the overall appearance of your smile. Mouthwashes that contain chlorhexidine gluconate (CG) are often marketed for the treatment of gum disease.
LISTERINE® Antiseptic is clinically proven to kill 99.9 % of germs that cause bad breath, plaque and gingivitis.
