Mouthwash is a common oral hygiene product. You see commercials for it on TV all the time, and a plethora of options line the shelves of the drugstore. Yet, when you see or hear oral health advice, mouthwash rarely comes up — “brush twice a day and floss daily” is the standard routine. So, you may be wondering, Do I really need to use mouthwash?
In this blog post, we’ll explore the role of mouthwash in maintaining optimal oral health and whether it should be an essential part of your daily routine.
What Does Mouthwash Do?
First, let’s discuss the purpose of this product. Mouthwash is a liquid you can swish around your mouth to reach areas that brushing and flossing might miss. It contains ingredients that kill bacteria, freshen breath, strengthen enamel, reduce plaque, and prevent cavities and gum disease. Some formulations, like those that include hydrogen peroxide, can even whiten your teeth over time.
When Should You Use Mouthwash?

Now, let’s answer the question on your mind: Do I really need to use mouthwash? If you’re good at thoroughly brushing at least twice a day and flossing at least once a day, you probably don’t need it. Mouthwash is meant to treat plaque and bacteria in hard-to-reach areas you may have missed with brushing and flossing. If you’re already an oral hygiene all-star, you’re probably okay to skip the mouthwash.
If you’re less fastidious about your oral hygiene, mouthwash is a great way to make up the difference. While it’s not meant to take the place of brushing and flossing, it’s a useful add-on treatment that can give your oral health a much-needed boost. Just make sure you’re not skipping the toothbrush and floss in favor of a quick rinse, as this can negatively affect your oral health over time.
When it comes to the best times of day to use mouthwash, there are differing opinions. The Mayo Clinic advises using it after brushing and flossing, while the UK’s National Health Service does not, as it could wash away the fluoride on the teeth deposited by the toothpaste. As a general rule, follow the manufacturer’s instructions regarding usage for best results, as some ingredients may necessitate a different order of use.
You can also use mouthwash after eating to remove food particles and bacteria and freshen your breath.
Choosing the Right Product
Staring down the oral hygiene aisle can be overwhelming, with dozens of brands, formulations, flavors, and active ingredients to choose from. Considering your unique oral health needs can help you narrow down the options and choose the perfect product for you.
There are two main types of mouthwash: cosmetic and therapeutic. Cosmetic options temporarily freshen breath and leave a pleasant taste in the mouth, but do not provide lasting health benefits. Therapeutic options, on the other hand, contain active ingredients to help control oral health conditions such as plaque buildup, gingivitis, halitosis, and tooth decay.
Common active ingredients include:
- Cetylpyridinium chloride and chlorine dioxide: Freshen breath by killing bacteria
- Chlorhexidine and essential oils: Control gingivitis and plaque
- Fluoride: Prevents tooth decay and strengthens enamel
- Carbamide peroxide and hydrogen peroxide: Whiten teeth and remove surface stains
- Enzymes and cellulose derivatives: Provide relief from dry mouth, also known as xerostomia
- Alcohol: Kills bacteria and reduces plaque
Products containing some of these active ingredients are only available via prescription. Talk to your dentist about your concerns to determine whether you need one of these specialized options.
Finally, keep in mind that alcohol, while it provides oral health benefits, is not always a necessary ingredient. If you have sensitive teeth, avoid mouthwash that contains alcohol, as it can worsen sensitivity. Consider choosing a product specially formulated for people who struggle with tooth sensitivity.
