Most of us grew up being taught the same simple oral care routine: brush your teeth with a soft toothbrush for 2 minutes, rinse your mouth with water, and spit. Rinsing after brushing teeth does seem like a natural final step in keeping your mouth clean and ready for the day ahead, but are you supposed to rinse after brushing your teeth?
This guide explores common questions like “Should you rinse before or after brushing?” and “After brushing teeth, should you rinse with water?”. Keep reading to help you decide whether your oral care routine needs a small upgrade.
Do you rinse after brushing your teeth? Rinsing after brushing can feel like a natural, refreshing way to wrap up your morning or evening routine. But is it bad to rinse your mouth after brushing? Some experts say yes.
Fluoride is a common ingredient in toothpaste and is often linked to a reduction in tooth decay and improved dental health.1 Fluoride toothpaste is also effective at strengthening tooth enamel when applied directly and left to sit on your teeth.2
While it may feel like a natural response, rinsing after brushing your teeth dilutes the protective effects of the fluoride.2 It's therefore recommended that you don't rinse your mouth with water after brushing, so that the fluoride can sit on your teeth for longer and provide the greatest protection.3
If you’ve just learned that you shouldn’t rinse your mouth after brushing, you may be wondering what you should be doing instead. Generally, it is recommended that you:2
If you use a fluoride mouthwash, you shouldn't use it to rinse your mouth straight after brushing. Instead, experts suggest using it at a different time of the day, such as after eating lunch, to allow the fluoride enough time to work its magic.3 Avoid rinsing your mouth with water or eating or drinking anything for 30 minutes after using a fluoride mouthwash, too.3
While it’s good to know that rinsing after brushing teeth isn’t the most effective method, it’s how you brush your teeth in the first place that is the most important factor for good oral health. Using the correct brushing technique and oral care tools is one of the best ways to ensure you are properly taking care of your mouth, helping the fluoride reach every surface of your teeth.
For a healthier, more effective clean, here are the recommended steps for brushing your teeth:
Brushing alone can’t reach between your teeth. Before brushing, using a dental floss or a power flosser like the Philips Sonicare Power Flosser 3000 daily can help remove plaque and food debris. This is a great way to support gum health and improve overall oral hygiene. With a nozzle that rotates 360 degrees, the Power Flosser 3000 can access hard-to-reach areas of your mouth and get a thorough clean in just 60 seconds.
Before you start brushing, it’s important to use a toothbrush that helps you get the most out of your routine. The Philips Next-Generation DiamondClean 9900 Prestige is designed to support a smarter, more personalised clean, using Next-Generation Sonicare technology to care for your teeth and gums. With 8 interactive modes and 3 intensity settings, you can tailor your brushing experience to your oral care needs, while SenseIQ technology supports a more intuitive brushing routine.
This intelligent toothbrush helps you brush more effectively and gently, removing 20x more plaque* for up to 15x healthier gums**. It also uses sonic action to distribute fluoride toothpaste evenly around the mouth. The result? Every tooth surface is thoroughly coated, allowing fluoride to stay in contact with enamel for longer and deliver maximum protection.
Spend 30 seconds focused on each of the four corners of your mouth twice a day to ensure full coverage. Use a fluoride toothpaste to help protect and strengthen your teeth.
If you’re not sure you’re brushing every corner of your mouth, try the Philips Next-Generation DiamondClean 9000. With smart coverage feedback, it guides your brushing in real-time using a clever light right, helping you follow a good brushing technique. You can then check out the post-brushing feedback to spot the areas you might have missed, and where you need to focus more of your attention when you next brush.
Brush your teeth gently in small circular motions away from the gum line. Remember to brush the outer and inner surfaces of each tooth.
To avoid brushing too hard, utilise the smart pressure feedback on your Philips Next-Generation DiamondClean 9900 Prestige. This guides your pressure in real-time for more effective cleaning while protecting your enamel and gums. After brushing, use your post-brush feedback to review your pressure and improve your technique over time.
After brushing teeth, should you rinse? Once you’ve finished brushing, avoid rinsing with water or mouthwash. Instead, spit out any excess toothpaste, and let the fluoride sit on your teeth to maximise its benefits.
Making small changes to your daily routine can have a big impact on your overall oral health. By skipping rinsing after brushing your teeth and simply spitting out the excess toothpaste, you allow the fluoride to stay on your teeth for longer. This helps strengthen enamel and keeps your teeth protected throughout the day when using a fluoride toothpaste. Pair this with an effective brushing technique and the right tools, and you’ll build a routine that supports long-term dental health.
