Brushing
How long should I wait to brush after eating?
Wait about an hour after anything acidic — citrus, fizzy cooldrink, wine. Acids leave enamel briefly soft, and brushing into it scrubs away the layer we work hard to protect. Swish water while you wait.
Why the wait matters
After anything acidic — citrus, a fizzy cooldrink, a glass of wine — the acids leave your enamel briefly softened. Brushing into it right then is like buffing a surface that hasn't set yet: you'd scrub away the very layer we work so hard to preserve. Giving it about an hour lets the enamel firm back up first.
This matters most after acidic food and drink. A plain meal with no acid isn't the same worry, but making the hour a habit after acidic things is the safe rule of thumb.
What to do in the meantime
While you wait, swish some water around your mouth or chew a piece of sugar-free gum. Both get your saliva flowing, which naturally neutralises the acid and rinses it away, settling everything back down without any scrubbing.
It's a small tweak to the timing rather than an extra chore — brush as normal, just not in the window right after something sharp or fizzy.
Common questions
Should I wait an hour after every meal?
Mainly after acidic food and drink — citrus, fizzy drinks, wine. That's when enamel is softened. After a non-acidic meal the risk is much lower, but the hour habit is a safe default.
What can I do right after eating instead?
Rinse with plain water or chew sugar-free gum. Both boost saliva, which neutralises the acid and washes it away naturally while you wait for the enamel to re-harden.
