Using mouthwash correctly can freshen your breath, help prevent cavities and treat gingivitis. There are two main types of mouthwash that you can choose. Cosmetic mouthwash masks bad breath but does not treat the cause of bad breath. Therapeutic mouthwash, on the other hand, does kill the bacteria that causes bad breath while reducing plaque, gingivitis, and cavities. Once you have chosen your mouthwash, use it once a day before or after brushing, or more often if your dentist instructs you to do so. Keep in mind, it’s important to always brush twice a day and floss at least once a day, regardless of whether you’re using mouthwash or not. [1]

Steps
-
Use cosmetic mouthwash to mask bad breath. If your aim is simply to freshen up your breath, there are a variety of products you can choose from to cover the bad odor. These leave your mouth tasting pleasant and temporarily make your breath smell better. Cosmetic mouthwash is a good choice for rinsing after you've eaten a particularly pungent meal, like garlic spaghetti sauce. It serves the same function as an after-dinner mint, with fewer calories. [2] X Research source
- If you have chronic bad breath, cosmetic mouthwash isn't going to address the source of the issue nor will it help reduce plaque, gingivitis, or cavities. It masks bad smells, but it doesn't kill the bacteria that produces them. The point of cosmetic mouthwash is just to make your mouth taste and smell good.
-
Use therapeutic mouthwash to fight bacteria. Therapeutic mouthwashes fight bacteria that cause bad breath while reducing plaque and treating gingivitis. Some may even whiten teeth. If you're looking for a mouthwash that actually cleans your mouth, choose one with therapeutic agents that will reduce harmful bacteria in your mouth. Look for an over-the-counter mouthwash in the toothpaste aisle that is labeled as being antibacterial or antiseptic.

- Using an antibacterial mouthwash may help you tackle the root of bad breath, which is often caused by bacteria. This is because it will kill bacteria and inhibit its reproduction in your mouth. That said, some antibacterial agents, such as such as chlorhexidine and cetylpyridinium, may discolor your teeth. [4] X Trustworthy Source American Dental Association World's largest dental professional organization and advocate for proper oral health Go to source
- You might also want to try an antiseptic mouthwash. This will stop the growth of bacteria as well as fungi, protozoa, and viruses. However, antiseptic mouthwash contains a lot of alcohol, which can dry out your mouth and cause irritation.

Use fluoride mouthwash to prevent cavities. If your goal is specifically to keep your teeth from getting cavities, you might want to choose a therapeutic mouthwash that contains fluoride. It helps to reduce the lesions that lead to cavity formation. Fluoride is in most commercially available toothpaste, and it is also added to the water in many cities, but you might want to consider using extra fluoride if your teeth are particularly prone to cavities. [6] X Research source
- Too much fluoride can be bad for you, but it’s not dangerous in the low levels found in toothpaste. It is also found naturally in water. Fluoride is really the best option if you want to re-mineralize the enamel on your teeth and prevent future cavities. [7]

Use prescription mouthwash for medical purposes. If you have an infection, mouth pain, lack of saliva (xerostomia), or another medical condition, your doctor or dentist might prescribe a special mouthwash to treat the problem. [8] X Trustworthy Source Cleveland Clinic Educational website from one of the world's leading hospitals Go to source Use the mouthwash as directed by your physician. Check the instructions that come with your prescription to learn about dosage and side effects.
-
Use herbal mouthwash to avoid dyes and chemicals. If you want to start using mouthwash, but would prefer to know exactly what you're using to rinse your teeth every day, choose one (or make your own) that is made with herbs that promote good oral health. Clove, peppermint and rosemary are all herbs that are traditionally used in preparations for the mouth and teeth due to their antibacterial, antiseptic and cooling properties.

-
Pour the proper dosage into a small cup. Read the instructions on the label of your mouthwash to learn the proper dosage. Your bottle of mouthwash may have come with a small cup (often the bottle's cap) you can use to measure the correct amount. If your bottle didn't come with a cup, pour the mouthwash into a small cup you've set aside for this specific purpose.
- Most mouthwashes will recommend a dose of about 20 ml. [10] X Research source This amount is enough to clean your teeth in one dose. Some fluoride mouthwashes, however, only require 10 ml.
- Unless you're using a prescription mouthwash, don't worry too much about using the exact amount. Use enough mouthwash to fill your mouth without making you feel uncomfortable. Always follow your dentist's instructions when using a prescription mouthwash.
-
Pour it into your mouth. Tip the cup into your mouth and pour in all of the mouthwash at once. Close your mouth to create a seal so that the mouthwash won't squirt out when you start swishing it. Do not swallow the mouthwash. It may contain strong chemicals that are not meant to be ingested.
-
Swish it through your teeth for 30 seconds to a minute. Follow the directions on the bottle to learn exactly how long you should swish the mouthwash. Make sure it swishes in front of and behind your teeth. Swish it through your molars as well as your front teeth. Swish it under your tongue and across the roof of your mouth, too.
-
Spit it out. When you're done swishing, spit it out into the sink. Rinse out the sink to get rid of the used mouthwash.
- Depending on what type of mouthwash you used, you might need to wait 1/2 hour or more before drinking water or eating in order to increase the effectiveness of the mouthwash. Read the directions on the bottle to find out if you should wait.

-
Use it before or after brushing. According to the American Dental Association, it doesn't matter whether you use mouthwash before or after brushing - both are equally effective. The more important thing is to use good quality mouthwash.
-
Use it to freshen your breath anytime. You can carry a little bottle of mouthwash with you during the day to refresh your breath after meals. If you have a problem with bad breath, this can be a good alternative to popping breath mints all day long. [11] X Trustworthy Source American Dental Association World's largest dental professional organization and advocate for proper oral health Go to source
-
Don't substitute it for brushing and flossing. Mouthwash is meant to be a supplement to other oral hygiene practices - not a replacement. [12] X Research source Make sure you continue to brush and floss your teeth as recommended by your dentist. In most cases you should brush twice a day and floss once a day. [13] X Expert Source Tu Anh Vu, DMD
Board Certified Dentist Expert Interview. 20 May 2020. Use mouthwash every time you brush, or just in the morning or at night - it's your choice. -
Ask your dentist for more information. If you're using mouthwash in an attempt to treat gingivitis, chronic bad breath, or cavities, you should make an appointment with your dentist to make sure you're using the right mouthwash. Mouthwash alone may not be effective enough to treat the problem you're dealing with, so it's important to get dental care before things get worse.
