Are Your Teeth Sensitive to Cold? Causes and Remedies


Are your teeth sensitive to cold? And what causes tooth sensitivity, anyway?

If you struggle to take a generous gulp of ice-cold water in the morning or biting into a delicious scoop of ice cream on a hot day, you likely have cold-sensitive teeth.

Tooth sensitivity is a common problem – but if you do experience it, there are ways to combat it. Read on to learn more about how to reduce and prevent tooth sensitivity.


Are Your Teeth Sensitive to Cold? Here’s Why.

Most people think that gum disease or tooth decay causes tooth sensitivity, but that’s not always the case.

There are all sorts of reasons someone may have cold-sensitive teeth.

The nerves within our teeth cause cold sensitivity, which occurs when the nerves within the tooth become exposed due to receding gums or worn tooth enamel.

Here are a few factors that cause this.


Plaque Buildup

Are your teeth sensitive to cold even when you’re not drinking or eating something cold? If this happens to you, it could be because of plaque buildup, which typically leads to cold sensitivity in teeth.

When left untreated, plaque buildup can lead to gum disease and tooth decay, which is why it is critical to visit your dentist at least once every six months for regular cleanings and checkups.


Receding Gums

Receding gums expose your nerves and make your teeth more sensitive to hot and cold food and drinks.


Bruxism (Teeth Grinding)

Bruxism wears away the enamel on your teeth, exposing the nerves and leading to tooth sensitivity. If you grind your teeth, your dentist can give you a mouth guard, which acts as a barrier between your teeth to protect them from grinding.

If you are unsure if you grind your teeth, look for these common signs:

  • Headaches
  • Jaw pain/stiffness
  • Earaches
  • Worn-down teeth
  • Disrupted sleep
  • Facial pain


Worn Tooth Enamel

Tooth enamel protects your teeth. When your enamel wears out, it exposes the nerve endings in your teeth, resulting in sensitivity to cold or hot food and drinks.


Overusing Products

Tooth whitening treatments, over-brushing your teeth, mouthwash with alcohol, and even whitening toothpaste can cause tooth sensitivity.


Gum Disease

Plaque buildup can lead to gum disease and tooth sensitivity. Regular brushing, flossing, and checkups at the dentist can prevent gum disease.


How to Combat Tooth Sensitivity

Toothpaste for Sensitive Teeth

Toothpaste like Sensodyne help reduces cold sensitivity by protecting your gums. These types of toothpaste are a great way to combat cold-sensitive teeth because they typically work very quickly – sometimes even right away.


Avoiding Acidic Food and Drinks

Highly acidic foods and drinks include:

  • Oranges
  • Wine
  • Coffee
  • Grapefruit
  • Lemons
  • Soda

By avoiding these types of foods and drinks, you can prevent tooth enamel from wearing off, which can significantly improve your sensitivity to cold.


Flossing and Brushing

Flossing and brushing with a soft toothbrush can both reduce and prevent gum irritation that causes teeth sensitivity.

If your teeth bleed when you brush, you are likely brushing too hard. Try brushing your teeth softly. Check out this blog post for helpful information on how to make the most from brushing your teeth.


Contact Your Dentist

If your teeth are sensitive to cold, it is always best to check with your dentist to find out the underlying cause.

A dentist can review your oral hygiene, detect cavities, and even catch gum disease early. Their job is to give you an overview of your oral health and hygiene. Regular checkups are an excellent way for dentists to spot issues that could turn into more significant, potentially more severe oral health problems down the road.

Many people experience gum disease and plaque buildup because they don’t see their dentist enough. Going to a dentist is a great way to ensure that you have optimal oral health.
