A simple question has divided people online for years: should you brush your teeth before breakfast or after? The debate recently resurfaced on social media, with a Reddit discussion attracting responses from people unsure of the correct answer. Some argued that brushing before breakfast is pointless because you are about to eat, while others said they could not imagine starting the day without brushing first.
The Great Brushing Debate
One Reddit user wrote: "Twice feels too much?" while another admitted they brush before breakfast simply because it is part of their morning routine. Others argued that brushing afterwards leaves them feeling fresher for the day ahead. To settle the debate, Dr Jyothi Chintamani from dental training course provider Dental Arch explained which approach dentists generally recommend and why.
Dr Jyothi said: "People are often surprised by the answer because on the surface it seems logical to eat first and brush afterwards. But when we look at what is happening inside the mouth, brushing before breakfast is usually the better option."
Why Brushing Before Breakfast Wins
According to Dr Jyothi, bacteria continue to build up in the mouth overnight while saliva production slows down. She said: "When you wake up in the morning, there have been several hours where your mouth has not had the same natural cleansing effect from saliva. Brushing first thing helps remove that build-up of plaque and bacteria before you start eating."
She explained that brushing before breakfast also provides an important protective benefit, adding: "When you brush with fluoride toothpaste, you are coating the teeth with fluoride before they are exposed to food and drink. That creates a protective barrier which can help protect the enamel from acidic foods and drinks consumed at breakfast."
Acidic Breakfast Foods and Enamel Protection
The issue becomes particularly important when popular breakfast choices such as fruit juice, smoothies, berries and coffee are involved. Dr Jyothi said: "Many breakfast foods and drinks are acidic, even some that are considered very healthy. Immediately after consuming something acidic, the enamel is temporarily softened. If you brush straight away, you are brushing against a surface that is more vulnerable to wear."
Rather than reaching for the toothbrush immediately after breakfast, Dr Jyothi recommends waiting. She said: "If you prefer brushing after breakfast, try to leave at least 30 minutes before brushing your teeth. This gives saliva time to neutralise acids and allows the enamel to recover."
Common Breakfast Brushing Myths
- Myth: You should always brush after breakfast. "Not necessarily. While it might feel cleaner, brushing immediately after acidic foods and drinks is not ideal."
- Myth: Coffee does not affect the timing. "Coffee is acidic, and that is something many people do not realise. Timing matters just as much with coffee as it does with fruit juice."
- Myth: The timing does not matter. "The timing can make a real difference over the years. Oral health is often shaped by small habits repeated every day."
- Myth: A quick rinse is the same as brushing. "Rinsing with water can be helpful after eating, but it does not remove plaque in the same way that brushing does."
Dr Jyothi says people should not become obsessed with getting it perfect. She said: "The most important thing is brushing twice a day with a fluoride toothpaste and maintaining a consistent oral hygiene routine. If you are currently brushing after breakfast, I would not want people to panic. The key takeaway is simply to avoid brushing immediately after acidic foods and drinks."
"For most people, brushing before breakfast is one of the easiest ways to protect their teeth while still keeping a simple morning routine," she added.
