Why sensitivity increases in summer: what pool water, the sea and iced acidic drinks do to enamel, and how to protect it.
Sensitivity increases in summer mainly because enamel meets acid more often through the day. Iced acidic drinks, fruit juice, frequent snacking and, for regular swimmers, poorly balanced pool water all soften the enamel surface temporarily.
Does pool water affect teeth?
A properly maintained pool is not a problem. Enamel erosion has been described in people who swim for hours regularly in pools where the disinfection balance has slipped and the water has become distinctly acidic; occasional holiday swimming does not carry the same risk.
- Water that stings the eyes and leaves a strong taste may indicate an imbalance
- Rinse your mouth with plain water after swimming
- Do not brush immediately afterwards; wait half an hour
- Mention sensitivity at your check-up if you swim regularly
Sea water and a dry mouth
Salt water leaves the mouth feeling dry, but the bigger effect is indirect: sweating in the heat with too little water reduces saliva flow, and less saliva means acid stays on the tooth surface longer. Drinking water steadily through the day is the simplest protection there is.
Acidic and iced drinks
The common summer mistake is stretching a cold drink over hours. What counts is not the quantity but the total contact time with acid, so one glass sipped over two hours does more than the same glass finished in ten minutes.
- Finish acidic drinks promptly rather than sipping
- A straw reduces contact with the front teeth
- Follow each drink with a mouthful of plain water
- Count lemon water and fruit juice as acidic too
- Wait about thirty minutes before brushing after anything acidic
Chewing ice is a genuine risk, particularly for filled, root-treated or crowned teeth, where it can start a crack. Our page on a fractured tooth explains what to do if that happens.
Temperature swings and sensitivity
An iced drink in hot weather creates a sudden temperature change. On healthy enamel that is a passing sensation, but where enamel is thin, the gum has receded or the margin of an old filling has opened, the same stimulus becomes a sharp pain. If it does not settle within a few days, or if pain lingers after the stimulus is gone, the tooth needs assessing.
Routines that slip on holiday
- Keep brush and paste somewhere visible where you sleep, not in the beach bag
- Clean between the teeth once a day, ideally in the evening
- Carry sugar-free gum while travelling
- Give children ice cream and juice with meals rather than through the day
Timing matters for cosmetic work in summer too, since coloured drinks are best avoided in the days after whitening; see our page on teeth whitening. If your gums bleed, our page on bleeding gums explains the next step. Our clinic is in Muratpasa and open 24 hours a day, seven days a week.
