Sensitive teeth ( dentin hypersensitivity ) affect about 30–35% of adults – that is, almost one in three people.【bmcoralhealth.biomedcentral.com†L1-L5】
People between 30 to 50 years of age , with sensitivity in women being particularly high during pregnancy. Tooth sensitivity tends to decrease with age.【link.springer.com†L10-L20】
Symptoms & most common triggers – when sensitive teeth really hurt
Sensitive teeth do not always become immediately noticeable – but many sufferers describe the pain as short, sharp and sudden , especially when the teeth are exposed to certain stimuli.
Studies show that it is mainly three triggers are the ones that most frequently cause complaints in practice:
-
cold Whether drinking ice-cold water, enjoying ice cream, or simply inhaling cold air, almost half of all patients with dentin hypersensitivity react with an unpleasant pulling sensation.【link.springer.com†L10-L20】
-
Chemical stimuli (acids) – Acidic foods such as vinegar, citrus fruits, pineapple, fruit juices, or soft drinks attack tooth enamel and further sensitize teeth, making them even more sensitive to cold or air.【opendentistryjournal.com†L1-L5】
Heat, on the other hand, is considered in studies to be a less intense stimulus It does cause movement in the dentinal tubules, but causes significantly less pain. [mdpi.com†L1-L5] Sweet foods alone are considered a rare trigger, but in combination with cold or acid, they can increase sensitivity.
👉 This means: Sensitive teeth react Not randomly , but very specifically – and the classic everyday situations are clear: a glass of cold water, the fresh winter air, or an acidic snack. It's precisely in these moments that the importance of stable, remineralized tooth enamel becomes apparent.
What are the causes of sensitive teeth?
Gum recession (gingival recession)
A large survey among dentists shows that 66% the client's gum recession is the main cause.【link.springer.com†L10-L20】
There are several factors that can lead to gum recession:
- Incorrect brushing technique or brushing too hard can cause micro-injuries, causing the gums to recede.
- Dentures or braces indicate mechanical stress in the tissue and can also lead to gum recession.
- Periodontitis or tartar lead to chronic irritation of the gums and can cause recession.
- Finally, a nutrient deficiency (e.g., vitamin C, calcium, magnesium, silicon, zinc) can also be the cause, causing the gums to lose stability and recede.
Degradation of tooth enamel (erosion, abrasion, attrition)
Approximately 59% Dentists also see enamel defects as a key cause for many clients【link.springer.com†L10-L20】.
- Acidic drinks (soft drinks, citrus fruits, wine) or stomach acid in the case of reflux attack the enamel.
- Frequent snacking increases acid load.
- Grinding (bruxism) and highly abrasive brushing further weaken the protective layer 【opendentistryjournal.com†L1-L5】.
Holistic treatment options
1. Eliminate causes
-
Brushing technique : Soft brush, gentle circular movements, prefer electric toothbrush.
-
Diet : Low-acid and low-sugar diet, reduce soft drinks.
-
Stress management : Relax your neck and jaw muscles; use a splint if you grind your teeth too much.
-
Care routine : Remineralize and strengthen teeth regularly.
👉 Tip: Integrate the EVARIE Enamel Care Serum As a daily routine—in the morning, after meals, and in the evening before bedtime. This ensures continuous remineralization and protection of teeth.
2. Hydroxyapatite – artificial tooth enamel
Hydroxyapatite (HAP) is the same substance that makes up our tooth enamel. Studies demonstrate its effectiveness:
-
Pain relief : An RCT showed that HAP significantly reduced pain sensitivity after just a few weeks 【nature.com†L1-L5】.
-
Tubule closure : HAP closes exposed dentinal tubules and thus prevents pain stimuli 【bmcoralhealth.biomedcentral.com†L1-L5】.
-
Remineralization : It repairs micro-defects and strengthens the tooth surface 【mdpi.com†L1-L5】.
Hydroxyapatite is now considered safe, biomimetic alternative that supports the natural remineralization of teeth – completely without fluoride.
