An ice cream in the summer or a cold gust of wind in the winter – and suddenly a stabbing pain shoots through your teeth. Many people suffer from sensitive teeth, but cold is a particularly common trigger for those affected. But why does tooth sensitivity react so strongly to cold, while acid is often less noticeable?
How common is the problem?
Sensitive teeth are not a rare phenomenon.
-
In a large European study with over 3,000 participants aged 18–35, 27% reported suffering from tooth sensitivity, and a full 42% were sensitive to cold air ( SpringerLink ).
-
Further reviews confirm that on average about one-third of the population is affected ( BMC Oral Health ).
-
The problem is particularly common between the ages of 30 and 40, and women are often slightly more affected ( ScienceDirect ).
Why cold has such a strong effect
The explanation is provided by the so-called hydrodynamic theory :
-
In the dentin there are tiny dentinal tubules that are filled with a fluid – the dentinal fluid.
-
Cold changes the pressure in these channels and sets the fluid in motion.
-
This movement stimulates the nerve endings in the pulp → flash of pain.
Studies show that when dentin is exposed , cold stimuli cause particularly severe pain because the fluid movement is very fast and direct ( SpringerLink ).
👉 This explains why cold sensitivity is so common, while acid-related irritation often only occurs after prolonged enamel degradation.
Causes of exposed dentinal tubules
-
Thin or worn tooth enamel
-
Gum recession (exposed tooth necks)
-
Microcracks caused by grinding or pressing
-
Acid erosion (e.g. from soft drinks, citrus fruits)
-
Brushing your teeth too hard or using the wrong toothpaste
What really helps: Regeneration instead of chemicals
The goal for sensitive teeth: to close dentinal tubules so that cold, heat and other stimuli no longer reach the nerve unhindered.
👉 Nano-Hydroxyapatite (HAp) – the natural main building block of tooth enamel –
-
repairs microcracks,
-
is deposited in the tooth surface,
-
reliably closes canals,
-
makes the tooth enamel strong and resistant again.
Unlike fluoride, EVARIE consciously focuses on fluoride-free, natural dental care .
Tips for everyday life
-
Brush with a soft brush and gentle pressure.
-
Avoid acidic drinks and aggressive whitening pastes.
-
Include products containing hydroxyapatite in your daily care routine.
The EVARIE solution
Our EVARIE enamel serums target exactly where cold sensitivity occurs:
-
Nano-hydroxyapatite strengthens tooth enamel and closes canals.
-
Herbal extracts such as sage, chamomile and coconut oil soothe gums and oral flora.
-
Vegan, alcohol-free, fluoride-free & sustainably produced .
-
Practical in a spray bottle – ideal for home and on the go.
Conclusion
Sensitive teeth in cold weather affect millions of people. Studies show that cold stimuli are particularly likely to trigger severe pain because they directly irritate the nerve via the dentinal tubules. With care that strengthens tooth enamel and closes the tubules, the cause can be targeted – completely without fluoride.
