Should I Use Mouthwash? The Complete Guide to Teeth Cleaning

Part of keeping your teeth clean on a regular basis requires knowing what products can help. This guide answers the question, "Should I use mouthwash?"

70% of Americans brush their teeth twice per day. Brushing more than this can actually damage the enamel. So what other tactics can you use to keep on top of your oral hygiene routine?



One trick is to use mouthwash, though many people still do not use it to the best of their ability. Read on as we answer the question "Should I use mouthwash?" 

History of Mouthwash

Mouthwash is no modern invention. As far back as 3000 BC, the ancient Chinese were using saline solutions to cure infections and illnesses in the gums. In ancient Greece, Hippocrates himself used a mix of vinegar and salt to clean his oral cavity. 



Luckily, mouthwash has evolved since then. One of the most famous brands today, Listerine, was one of the first proprietors in the late 1800's. It was used to reduce infection after surgery but was not popular until around five years later. 

Benefits of Mouthwash

There are several benefits to using mouthwash. Primarily, it can reach places that brushing can not. Below are the main benefits of using mouthwash. 

Prevents Cavities

Even with a robust oral hygiene routine, cavities can still develop. This can be down to the food you eat and even genetics. No one wants to find out that they need a filling and mouthwash can safeguard against it. 

The reason for this is that it contains fluoride. This element strengthens the tooth enamel, preventing acid from getting inside. Combined with the ability of mouthwash to clear bacteria and you have a double-edged attack when you introduce a daily mouthwash routine. 

Reduces Plaque

Plaque can develop quickly on teeth, weakening enamel and causing gum disease. The best way to get rid of this is by brushing and flossing. Mouthwash should not replace this, but it can strip away extra bacteria making the effectiveness of these much more potent. 

Freshens Breath

Everyone needs a quick breath freshen once in a while. You may have a recurring problem, or it may just be that you ate a pungent meal. Mouthwash will strip away the odors in the mouth, leaving a pleasant smell behind. 

Clears up Canker Sores

Canker sores develop as small liaisons at the base of the gums. While they are not contagious, they can be very sore. The alcohol in some mouthwashes can help sterilize the area and clear up canker sores much quicker. 

When Should I Use Mouthwash?

Mouthwash should not replace daily brushing and flossing. Its purpose is to destroy any bacteria that form. However, it does not remove the food and lodged in items that brushing can do. 

Mouthwash should work alongside your current oral health regime. It is also not recommended that it be used every day unless it is a weaker mouthwash. In fact, stronger ones should be limited to times when infections, bad breath, and gum disease are inherent. 

Before or After Brushing?

This is down to personal preference unless instructions from elsewhere state otherwise. Some manufacturers may tell you to use it after brushing to increase the effectiveness. 

Should you use it after brushing, wait at least 30 minutes. This allows the fluoride from our toothpaste to stay in the mouth for some time and not get washed away immediately. 

Can I Use It During Pregnancy?

It is perfectly safe to use mouthwash during pregnancy. The fluid can help protect the teeth from decay that may occur when minerals in the body are low. You may wish to opt for alcohol-free washes and natural sodium fluoride just in case. 

Using Mouthwash and Braces

Fixed braces are notoriously hard to keep clean. This is because of the intricate metalwork and small spots around them. It is not uncommon to see signs of plaque and decay even with a sound dental regime. 

Mouthwash can assist in this greatly, eliminating harmful bacteria in tough to reach spots. 0.05% sodium fluoride mouthwash is a good place to start.

Which Mouthwash Should I Use?

There is a wide range of mouthwashes from different brands and manufacturers. What is more important than the company you buy from is what the mouthwash contains. Different rinses work better for different situations. 

Mouthwashes that are alcohol-free are best for people who suffer from dry mouth. Alcohol can dry the area out, making the problem worse. The only downside is that they do not tend to work as well at eliminating bacteria.



People who have a history of tooth decay and developing cavities should go for mouthwashes containing fluoride. Gum disease sufferers should opt for anti-plaque and anti-gingivitis-specific blends. 

Can My Children Use Mouthwash?

If swallowed, mouthwash can cause problems. Not only does some of it contain alcohol, but high fluoride levels may also upset some children medically. Therefore, you should not give mouthwash to children under six years old or anyone who may not understand that it should not be ingested. 

Older children and teens can benefit from mouthwash, but it should not be used every day. Get a weak, alcohol-free one and introduce it to their cleaning regime. The extra fluoride can also help strengthen the teeth in their teen years. 



One time it is advised is if the child is wearing braces. Mouthwash can eliminate bacteria in places brushing and flossing can not get to.
