Tooth sensitivity, also known as dentinal hypersensitivity, occurs when the enamel's protective layer thins or when the gum recedes. These phenomena expose the dentine, a more porous inner layer containing tiny channels connected to the dental nerve. Cold travels rapidly through these channels, triggering a brief but intense pain.

The most common causes:
- Overly vigorous brushing that wears down the enamel.
- Acid erosion linked to sugary drinks and citrus fruits.
- Gum recession, sometimes due to age or chronic inflammation.
- Bruxism (teeth grinding).

How do ice cream and iced drinks make sensitivity worse?

Extreme cold directly stimulates the nerve endings beneath the enamel. The more exposed the tooth, the faster the pain signal travels.
Commercial ice creams combine two factors:

• Intense cold
• The presence of sugars, which acidify the oral environment and promote enamel wear.

That's why some people feel an immediate twinge when biting into an ice cream or drinking an iced beverage.

The right habits to protect your sensitive teeth

1️- Brush gently
Opt for a soft-bristled brush and light circular movements. Strength is not the same as effectiveness: aggressive brushing weakens enamel and gums. We recommend the The Smilist toothbrush, ultra-soft, with 10,000 bristles !

2️- Use the right toothpaste
Not all formulas are equal when it comes to sensitive teeth. Choose a toothpaste specifically designed to reduce sensitivity whilst strengthening enamel.

At The Smilist, our Whitening Remineralising Toothpaste is formulated without fluoride, enriched with minerals and protective probiotics. It gently helps remineralise and preserve the natural balance of the oral microbiome. A gentle, effective, and clean solution for rediscovering the comfort of your smile!

3️- Limit thermal shocks
If your teeth are very sensitive, avoid going abruptly from hot to cold. Let your ice cream soften slightly before eating it, and drink iced liquids in small sips.

4️- Protect your enamel
Reduce your intake of highly acidic foods (fizzy drinks, vinegar, excess citrus) and always rinse your mouth with water after consuming them.

5️- Maintain gentle interdental hygiene
Daily cleaning of the spaces between teeth prevents gum inflammation, which worsens sensitivity.

What should you do if the sensitivity persists?

If your sensitivity does not improve despite these precautions, we recommend:
- Consulting your dentist for a full check-up.
- Assessing for erosion, cavities, or gum recession.
- Considering the application of protective varnishes or specific in-practice treatments.

In summary

Tooth sensitivity is common, especially in summer when cold foods are everywhere. With a mindful hygiene routine and a few adjustments, it is entirely possible to enjoy your ice cream without pain.
