Mouthwash: How to Choose It and Use It for a Healthier Smile

With so many mouthwash products available on the market, it can be overwhelming to know which one is right for you or how to use it effectively. From formulas targeting bad breath or dry mouth to those designed for gum health or cavity prevention, the variety of options can make it difficult to decide where to start. Additionally, knowing how often to use mouthwash, whether to rinse before or after brushing, or what ingredients to look for can add to the confusion. Choosing the wrong product or using it incorrectly can limit its effectiveness, which is why getting expert advice tailored to your unique oral health needs is so important.

What Mouthwash Is…And Isn’t

Simply put, mouthwash is a liquid solution that’s designed to rinse your mouth, freshen your breath, and help improve your oral health. Unlike water, mouthwash contains active ingredients that target bacteria, plaque, and other factors that contribute to bad breath and gum disease. 

Some of the key ingredients you’ll find in mouthwash include fluoride, which helps strengthen enamel and prevent cavities, and antiseptics like chlorhexidine or cetylpyridinium chloride, which fight bacteria that cause gum disease and bad breath. The combination of these ingredients works together to reduce bacteria, fight germs, and leave your mouth feeling fresh.

However, mouthwash is NOT a substitute for brushing. Brushing your teeth is the only way to limit the accumulation of food particles, plaque, and tartar on the surfaces of your teeth. Mouthwash can help flush out some harmful bacteria from your mouth and freshen your breath, but it cannot remove sticky plaque or food debris from deep between your teeth and along the gum line.

Mouthwash is also NOT a substitute for routine dental care from a professional. While it can temporarily mask problems like bad breath and gum sensitivity and support cavity prevention, mouthwash cannot make them go away. You still need to visit a dentist at least twice a year for a thorough cleaning and oral exam.

A Brief History of How Mouthwash Was Invented

The earliest versions of mouthwash can be traced back to ancient civilizations, like the Egyptians and Romans, who used mixtures of herbs, spices, and even vinegar to freshen their breath and promote oral health. 

Fast forward to the 1800s, and mouthwash becomes a commercial product, adding alcohol as a way to fight germs and bacteria. One of the earliest was a formula created by Dr. Joseph Lawrence in the 1870s, which was originally marketed as a surgical antiseptic and floor cleaner before being sold as a mouthwash. Named after an English surgeon who pioneered antiseptic medicine, Listerine is still one of the most popular brands of mouthwash.

In the 1960s, chlorhexidine was identified as an effective treatment against plaque buildup, and alcohol-free versions were introduced in the early 1990s.

Over the years, mouthwash has continued to evolve with new ingredients and better formulations, becoming more effective at fighting bacteria, preventing cavities, whitening teeth, and freshening breath while being easier and safer to use.

5 Common Types of Mouthwash

Today, there are as many different types of mouthwash as there are unique dental needs. Some of the most common are:

  1. Antiseptic. These mouthwashes are designed to kill bacteria, reduce bad breath, and fight gum disease. They often contain ingredients like alcohol, chlorhexidine, or cetylpyridinium chloride.
  2. Plaque-inhibiting. These help reduce plaque buildup, which can cause cavities and gum disease. They usually contain ingredients like fluoride or zinc, which work to prevent plaque from sticking to your teeth.
  3. Preventative. This is the standard fluoride mouthwash that focuses on keeping your oral health in check and protecting against cavities before they start.
  4. Therapeutic. These mouthwashes are meant to treat specific oral health issues, like gum disease or infections. They may include antimicrobial agents or other ingredients to help manage these conditions.

Other. There are even more specific mouthwashes for more particular needs, such as xerostomia, gingivitis, halitosis, whitening, pain relief, or hypersensitivity.

3 Reasons You Should Use Mouthwash

Although it’s not meant to replace brushing and flossing, there are still plenty of reasons why adding mouthwash to your daily oral hygiene routine is a good idea.

  1. It offers a deeper clean. While your toothbrush does a pretty great job of cleaning your teeth, it can’t reach every nook and cranny in your mouth. Mouthwash can get into those hard-to-reach areas to rinse out bacteria and food particles that hide between teeth and along the gumline.
  2. It can help prevent other problems. Many mouthwashes have ingredients that fight bacteria and reduce plaque, helping to prevent gum disease, tooth decay, cavities, and bad breath.
  3. It can brighten your smile. Some mouthwashes contain hydrogen peroxide or non-abrasive whitening ingredients that help brighten your smile over time, for a grin that positively glows.

How to Choose the Right Mouthwash

Finding the right mouthwash is key to addressing your unique oral health needs, whether that’s combating bad breath, preventing gum disease, or protecting against cavities. Unlike generic options that only mask odors temporarily, a mouthwash with targeted active ingredients can provide lasting benefits and actively improve your oral health. By incorporating the right product into your routine, you can take a proactive step toward maintaining a healthier smile and long-term dental wellness.

Some things to consider include:

Your unique needs. Are you battling bad breath, experiencing tooth sensitivity, or trying to treat gum disease? Choose a mouthwash that’s formulated to address your specific problem.

Active ingredients. Similarly, certain active ingredients will be more effective at meeting your needs. For example, antibacterial ingredients are ideal for plaque control, while cetylpyridinium chloride is effective for managing gingivitis and gum disease. Fluoride is a proven tool for preventing cavities and strengthening enamel, but consider whether or not you need alcohol in your mouthwash, because it can worsen dry mouth or exacerbate sensitive gums.

Special populations will also benefit from a closer look when selecting a mouthwash, such as:

  • Kids. Kids are at a higher risk for cavities and may not always brush or floss as thoroughly as they should. A fluoride mouthwash designed for children can help strengthen enamel and prevent cavities. Just make sure to choose one that’s alcohol-free, as younger children might swallow it by accident.

  • High risk for cavities. If you have a history of cavities, a fluoride mouthwash is your best bet. Some mouthwashes even contain xylitol, which helps fight the bacteria that cause cavities.

  • Braces. If you’re wearing braces, mouthwash can help rinse out food particles and reduce plaque buildup. We recommend looking for an alcohol-free mouthwash that will be gentle on your gums.

How to Use Mouthwash Effectively

Proper usage is just as important as choosing the right product. As with most hygiene products, mouthwash is most effective when used as directed. For the best results, always follow the instructions on the bottle, as different mouthwashes may have slightly different guidelines.

The most important thing about using mouthwash is that consistency is key. If you use mouthwash regularly and as directed, you’ll get the full benefits, which can include fresher breath and healthier gums.

For most types of mouthwash:

  • Pour 20 mL (about 4 teaspoons) of mouthwash into the cap.
  • Swish it around your mouth for 30-60 seconds. Make sure it gets into all areas of your mouth, including between your teeth and along the gumline.
  • Spit it out—don’t swallow!
  • For the best results, use mouthwash after brushing and flossing, ideally once or twice a day.

Also, make sure not to rinse with water after using mouthwash, as it can wash away some of the beneficial ingredients left behind. 

Whether you use mouthwash before or after brushing and flossing is a matter of personal preference. The key is to consistently incorporate it into your daily oral hygiene routine, and not as a standalone solution.
