If mouthwash is part of your oral care routine, you may have wondered whether you should use it before or after brushing your teeth.
The short answer is: it depends on the type of mouthwash you’re using.
One thing is clearer: you generally shouldn’t rinse your mouth with water immediately after brushing with fluoride toothpaste. Instead, spit out the excess toothpaste and avoid rinsing so that more fluoride remains on your teeth.
When it comes to mouthwash, the best timing depends on its active ingredients, its intended purpose, and the product instructions. Some mouthwashes can be used at a separate time from brushing, while certain therapeutic products may have specific directions about when to use them.
Let’s look at how mouthwash fits into a good oral hygiene routine and how to get the most benefit from it.
Key Takeaways
- After brushing with fluoride toothpaste, spit out the excess toothpaste instead of immediately rinsing with water.
- Don’t automatically use mouthwash immediately after brushing. Check the product instructions or follow your dentist’s recommendation.
- For many everyday mouthwashes, using the rinse at a different time from brushing can be a practical option.
- Some therapeutic mouthwashes have specific instructions and may be recommended for use after brushing.
- Mouthwash can complement brushing and cleaning between your teeth, but it doesn’t replace either one.
- Choose a mouthwash based on your oral health needs rather than simply its flavor or how strong it feels.
- If your dentist prescribes or recommends a particular mouthwash, follow the instructions they provide.
1. What Does Mouthwash Actually Do?
Mouthwash, also called mouthrinse, is a liquid oral care product that you swish around your mouth and then spit out.
However, not all mouthwashes do the same thing.
Mouthwashes can broadly be divided into cosmetic and therapeutic products.
Cosmetic mouthwashes primarily freshen your breath and leave your mouth feeling clean. These effects may only be temporary.
Therapeutic mouthwashes contain active ingredients intended to provide specific oral health benefits. Depending on the formulation, they may help prevent tooth decay, reduce plaque or gingivitis, or control bad breath.
Common active ingredients can include fluoride, cetylpyridinium chloride (CPC), essential oils, peroxide, and chlorhexidine.
Some mouthwashes are available over the counter, while certain formulations may be recommended or prescribed by a dentist.
Mouthwash can help supplement your daily oral hygiene, but it doesn’t physically remove plaque the way brushing and cleaning between your teeth do.
Think of it as an additional tool, not the foundation of your oral care routine.

2. Should You Use Mouthwash Before or After Brushing?
There isn’t one answer that applies to every mouthwash.
The best timing can depend on the product’s active ingredients and instructions.
What we generally want to avoid is unnecessarily washing away the fluoride left on your teeth after brushing.
When you brush with fluoride toothpaste, some fluoride remains on your teeth after you spit out the excess toothpaste. Keeping fluoride in contact with your teeth helps maximize its protective effect against tooth decay.
That’s why the usual advice after brushing is simple:
Spit, but don’t immediately rinse with water.
As for mouthwash, check the label. If the product doesn’t specifically need to be used after brushing, using it at another time of day can be a convenient option.
If your dentist has prescribed or recommended a particular rinse, follow their instructions.

3. Can You Use Mouthwash Before Brushing?
For many products, you can use mouthwash before brushing if the label allows it.
One advantage is that you won’t be rinsing fluoride toothpaste off your teeth afterward.
However, don’t rely on a pre-brushing rinse to do the work of your toothbrush.
Plaque is a sticky biofilm that needs to be disrupted mechanically. Brushing and cleaning between the teeth therefore remain the most important parts of your daily oral hygiene routine.
If you’re using mouthwash to manage a specific problem, such as a high risk of cavities, gingivitis, or another oral condition, ask your dentist about the most appropriate timing.

4. Why Shouldn’t You Rinse With Water Immediately After Brushing?
Fluoride is one of the most important ingredients in toothpaste because it helps protect teeth against decay.
After brushing, fluoride from your toothpaste remains on and around your teeth.
Rinsing thoroughly with water immediately afterward washes away and dilutes some of this fluoride.
For that reason, after brushing with fluoride toothpaste:
Spit out the excess toothpaste, but don’t immediately rinse your mouth with water.
This advice is particularly relevant in the Philippines, where local public-health recommendations encourage the use of fluoride toothpaste and advise against rinsing with water immediately after brushing.

5. When Is a Good Time to Use Mouthwash?
If your mouthwash doesn’t have specific instructions requiring it to be used immediately before or after brushing, you can consider using it at another time of day.
For example, a simple adult routine might look like this:
Morning: Brush your teeth for about two minutes with fluoride toothpaste. Spit out the excess toothpaste without immediately rinsing with water.
During the day: If you use an everyday mouthwash, you might use it after lunch or at another convenient time, following the directions on the label.
Before bed: Clean between your teeth using floss or another interdental cleaning method appropriate for you, then brush thoroughly with fluoride toothpaste. Spit out the excess toothpaste without immediately rinsing with water.
This is only an example. You don’t necessarily need mouthwash after every meal or even every day unless the particular product or your dentist recommends it.
If you’re using a prescription or therapeutic mouthwash, follow its specific instructions instead.

6. Does the Type of Mouthwash Matter?
Absolutely. The right mouthwash depends more on what you’re trying to accomplish than on whether you prefer a particular flavor.
Fluoride Mouthwash
Fluoride mouthwash can provide additional protection against tooth decay and may be useful for people who need additional fluoride exposure.
However, your individual need for a fluoride rinse depends on factors such as your cavity risk, fluoride toothpaste use, age, and overall oral health.
Ask your dentist whether adding one would be beneficial for you.
Antimicrobial Mouthwash
Certain therapeutic mouthwashes contain active ingredients that can help control plaque, gingivitis, or bacteria associated with bad breath.
The appropriate product and duration of use depend on its active ingredients.
Chlorhexidine Mouthwash
Chlorhexidine is an antimicrobial ingredient used in certain therapeutic oral rinses.
It shouldn’t simply be treated like an everyday breath-freshening mouthwash. Depending on the formulation and reason for use, there may be specific instructions regarding frequency, duration, and timing.
If your dentist recommends a chlorhexidine rinse, use it exactly as directed.
Cosmetic Mouthwash
Cosmetic mouthwashes primarily help freshen breath and improve the taste or feeling in your mouth.
They can make your mouth feel cleaner, but fresh breath doesn’t necessarily mean that a product is preventing cavities or treating gum disease.

7. What About Alcohol-Free Mouthwash?
You’ll find both alcohol-containing and alcohol-free mouthwashes in the Philippines.
A mouthwash isn’t automatically more effective simply because it contains alcohol. The active ingredients and intended purpose of the product are more important.
Some people may also find alcohol-containing rinses uncomfortable, drying, or irritating.
If you have dry mouth, sensitive oral tissues, or experience persistent burning or irritation when using mouthwash, talk to your dentist about whether another formulation would be more suitable.

8. Can You Use Too Much Mouthwash?
More mouthwash doesn’t necessarily mean better oral health.
Using more than the recommended amount, rinsing more frequently than directed, or swishing for much longer than recommended doesn’t necessarily provide additional benefits.
Depending on the product, inappropriate or excessive use may also cause irritation or other unwanted effects.
Follow the directions on the label. If you’re using a therapeutic or prescription mouthwash, follow your dentist’s instructions regarding how much to use, how often to use it, and for how long.
And remember: mouthwash shouldn’t become a shortcut that replaces proper brushing or cleaning between your teeth.

9. Can Children Use Mouthwash?
Children require additional care when it comes to mouthwash because they may accidentally swallow it.
Mouthwash is generally not recommended for children younger than 6 unless a dentist specifically advises its use. For older children, whether a mouthwash is appropriate depends on their ability to reliably swish and spit it out, the type of product, and their individual oral health needs.
For young children, proper brushing with an appropriate amount of fluoride toothpaste is generally much more important than adding mouthwash.
Parents should check the age recommendations and directions on the product label rather than assuming an adult mouthwash is appropriate for a child.
If you’re considering a fluoride or therapeutic mouthwash for your child, particularly because of frequent cavities or another dental concern, ask your child’s dentist first.

10. Mouthwash Doesn’t Replace Brushing and Cleaning Between Your Teeth
Even an excellent mouthwash can’t compensate for inadequate brushing.
Plaque adheres to your teeth as a biofilm. Brushing physically disrupts and removes it from accessible tooth surfaces, while floss, interdental brushes, or other suitable methods can help clean between the teeth.
Mouthwash can provide additional benefits depending on its ingredients, but it doesn’t perform this mechanical cleaning for you.
A good oral care routine should therefore focus on:
- Brushing at least twice a day with fluoride toothpaste, including before going to bed.
- Cleaning between your teeth regularly using floss, interdental brushes, or another method recommended by your dentist.
- Using mouthwash when appropriate for your individual oral health needs.
- Limiting frequent consumption of sugary foods and drinks to help reduce your risk of tooth decay.
- Having regular dental examinations at intervals appropriate for your oral health needs.

11. Common Mouthwash Myths
Myth: Mouthwash can replace brushing when you’re in a hurry.
Fact: Mouthwash doesn’t mechanically remove plaque as effectively as brushing. It should complement your oral hygiene routine rather than replace brushing.
Myth: You should rinse until all the toothpaste is gone.
Fact: After brushing with fluoride toothpaste, spitting out the excess without immediately rinsing with water allows more fluoride to remain in contact with your teeth.
Myth: Mouthwash should always be used after brushing.
Fact: Not necessarily. The best timing depends on the particular mouthwash. Some can be used at another time of day, while therapeutic products may come with specific instructions.
Myth: The stronger a mouthwash burns, the better it’s working.
Fact: A burning sensation isn’t a reliable measure of effectiveness. Pay attention to the active ingredients and what the product is intended to do.
Myth: Everyone needs mouthwash.
Fact: Mouthwash can be helpful, but it isn’t essential for everyone. Your need for one depends on your oral health, cavity risk, gum health, and other individual factors.
Myth: Mouthwash can permanently cure bad breath.
Fact: Mouthwash may help control bad breath, but persistent bad breath can have an underlying cause. Dental problems, gum disease, plaque buildup, dry mouth, tobacco use, and other factors may contribute.
If bad breath continues despite good oral hygiene, have it evaluated by a dentist.
The Bottom Line
So, should you use mouthwash before or after brushing?
There isn’t one rule that applies to every mouthwash.
After brushing with fluoride toothpaste, the important thing is to spit out the excess toothpaste and avoid immediately rinsing thoroughly with water so that fluoride can remain in contact with your teeth.
For mouthwash, check the product’s directions. If it doesn’t specifically need to be used around brushing, using it at a separate time of day can be a practical option. If your dentist has recommended a therapeutic mouthwash, follow their instructions.
Most importantly, remember that mouthwash is an addition to, not a replacement for, brushing with fluoride toothpaste and cleaning between your teeth.
Frequently Asked Questions
1. Should I use mouthwash before or after brushing?
It depends on the mouthwash. You don’t need to automatically use it immediately after brushing. Check the product instructions and follow your dentist’s recommendation. If no specific timing is required, using mouthwash at a different time from brushing can be a practical option.
2. Should I rinse with water after brushing my teeth?
Generally, no. After brushing with fluoride toothpaste, spit out the excess toothpaste instead of immediately rinsing your mouth thoroughly with water. This helps maintain fluoride around your teeth for longer.
3. How long should I wait before using mouthwash after brushing?
There isn’t one waiting period that applies to every mouthwash. Rather than focusing on an exact number of minutes, check the instructions for your product. If it doesn’t need to be used after brushing, consider using it at a separate time of day.
4. Can I use mouthwash after lunch?
Yes, for many everyday mouthwashes, this can be a convenient way to separate mouthwash use from your morning and nighttime brushing. Follow the directions on the product label.
5. Should I rinse with water after using mouthwash?
Follow the product instructions. For many mouthwashes, rinsing with water immediately afterward isn’t necessary and may wash away active ingredients intended to remain in the mouth.
6. Can I use mouthwash every day?
Many mouthwashes are designed for daily use, but not every product should be used in the same way or for the same length of time. Follow the label or your dentist’s instructions.
7. Do I need mouthwash if I already brush and floss?
Not necessarily. Mouthwash is an additional oral care tool. Some people may benefit from a therapeutic mouthwash because of their risk of cavities, gingivitis, bad breath, or another condition, while others may not need one.
8. Is fluoride mouthwash better than regular mouthwash?
It depends on your goal. Fluoride mouthwash is designed to help protect against tooth decay, while other therapeutic rinses may target plaque, gingivitis, or bad breath. Cosmetic mouthwashes primarily freshen breath.
9. Is alcohol-free mouthwash better?
Not necessarily for everyone. An alcohol-free product may be more comfortable for some people, particularly those who experience dryness or irritation. The best choice depends on the product’s active ingredients and your individual oral health needs.
10. What should I do if mouthwash burns or irritates my mouth?
Stop using a product if it causes significant or persistent irritation and consult your dentist. A different formulation may be more appropriate.
11. Can mouthwash get rid of bad breath permanently?
Not necessarily. Mouthwash can temporarily freshen breath or help control odor-causing bacteria, depending on the product. Persistent bad breath may indicate an underlying dental or oral health issue and should be assessed by a dentist.
12. How do I know which mouthwash is right for me?
Start by considering why you want to use one. Preventing cavities, managing gingivitis, controlling bad breath, and treating a dental condition may require different products.
Your dentist can recommend an appropriate mouthwash based on your oral health, medical history, medications, and risk factors.
