Explore simple timing shifts for maintaining brighter and healthier smiles

For millions of coffee drinkers, the morning ritual is sacred, but the sequence of hygiene remains a point of contention.

Dr Mark Burhenne, a San Francisco-based dentist with over forty years of experience, recently shared insights into why the traditional order may be backward.

In a post shared on 20 February 2026, he explained that the primary cause of staining is the microscopic environment of the mouth after sleep.

"When you drink coffee before brushing your teeth, the milk proteins stick better to your teeth, because last night’s biofilm is sticky," Dr Burhenne said.

This layer of bacteria and proteins, known as biofilm, accumulates on tooth enamel overnight. According to the expert, this substance acts like a magnet for dark pigments and dairy additives.

He described seeing distinct brown staining on the teeth of frequent latte and cappuccino drinkers, noting that this "velcro" layer is what allows discolouration to latch on so effectively.

The 'simple fix'

To maintain a bright smile and protect oral health, Dr Burhenne argued that preemptive action is essential. He suggested a minor adjustment to the morning schedule to prevent buildup entirely. To protect your teeth, follow these expert-led steps:

• Brush your teeth immediately upon waking to remove biofilm.
• Apply fluoride toothpaste to create a protective barrier.
• Wait until after brushing to consume your first cup of coffee.
• Avoid brushing for at least thirty minutes after drinking acidic beverages.

"It’s such a simple fix: brush before your coffee, not after," he concluded. Beyond aesthetics, brushing immediately after coffee can be harmful because the beverage's acidity temporarily softens the enamel.

Brushing right away can scrub away this weakened surface, whereas cleaning beforehand ensures the enamel remains strong and resistant to long-term damage.
