Brushing your teeth twice a day is the standard of good oral hygiene.1 Typically, this means brushing once in the morning and once at night, making it easy to keep up a solid dental hygiene routine. What’s less clear, though, is exactly when you should be brushing in the morning, particularly when it comes to breakfast.
Do you brush your teeth before breakfast or after? There are many differing opinions on the topic.
It’s important to consider enamel, oral hygiene, and your personal routine when it comes to brushing before or after breakfast.
To protect your teeth and maintain good oral hygiene, it’s recommended to brush your teeth before breakfast. That means bumping up brushing on your to-do list so that it’s one of the first things you do once you wake up.
Brushing before eating breakfast in the morning is recommended partly due to the buildup of bacteria and plaque on your teeth. Overnight, your mouth’s salivary production decreases, creating a drier environment that bacteria thrive in.2 By brushing your teeth when you wake up, you remove this buildup and help freshen your breath for the day ahead.
Brushing your teeth before eating also coats your teeth with fluoride from your toothpaste, which protects enamel from the acids and sugars in your breakfast.3 Whether you prefer cereal, porridge, or a smoothie bowl in the morning, this is good news for your oral hygiene and makes it easier to steer clear of cavities and decay.
For an effective yet gentle clean, a tool like the Philips Sonicare Next Generation DiamondClean Series 8000 can help support your routine. It helps guide your brushing with smart pressure feedback, letting you know when you may be brushing too hard, while personalised post-brushing feedback helps you spot areas to focus on next time. With a choice of brushing modes and intensity levels, you can tailor your clean to your needs. Powered by Next-Generation Sonicare technology, it removes up to 20x more plaque* while remaining gentle on teeth - ideal for tackling overnight build-up and starting your day feeling fresh.
When considering ‘should you clean your teeth before or after breakfast?’, brushing first clearly comes with advantages. In comparison, brushing after breakfast may not do much good for your teeth.
Consuming acidic substances, like your morning orange juice or cheese on toast, softens the surface of your enamel, making it far easier to remove when brushing.3 If you make it a habit of brushing your teeth after breakfast, you can end up removing the entire surface layer of enamel, leaving your teeth more vulnerable to sensitivity, discolouration, and chipping.4
We’ve answered, ‘Are you supposed to brush your teeth before or after breakfast?’, but what if it doesn’t suit your routine?
While brushing your teeth before eating is preferable, there are times when you’ll need to brush a little later in the morning. When this happens, follow these key steps to protect your enamel while maintaining good oral hygiene:
To stay informed, read our handy guide on what you can eat before and after brushing your teeth.
If you’re wondering when to brush your teeth in the morning, your best bet is to get it done as soon as you wake up and before consuming any foods or liquids (that includes your morning coffee!). By brushing immediately, you remove bacteria and plaque that have built up overnight, and coat your teeth with fluoride to protect the enamel before you eat.
Make sure to wait at least 30 minutes after brushing to eat or drink, as doing so too early can wash away any fluoride from the toothpaste that is working to protect your teeth.1
If you’re cleaning your teeth before breakfast, follow your normal dental hygiene routine. Make sure you don’t rinse with water, or eat or drink for at least 30 minutes after brushing, as this washes away the fluoride from your toothpaste and leaves your enamel more at risk of erosion.1
If you’re brushing after eating, you should also wait 30 minutes after consuming any food or acidic drinks (like fruit juice), giving your saliva enough time to dilute the acid.
Yes, you should brush once in the morning and once at night. Brushing before bed is a great way to get rid of food and bacteria that build up during the day, but your mouth doesn’t stay spotless overnight. By brushing when you wake up, you remove the bacteria and plaque that’s accumulated while you slept, giving your mouth a fresh start for the day ahead.
When it comes to the question of ‘Should I brush my teeth before or after breakfast?’, the final choice is down to you. If it works with your morning schedule, brush before eating to protect your enamel. More importantly than brushing after or before breakfast, though, is making sure you allow enough time for adopting a strong dental hygiene routine.
