Winter can be a delightful season, bringing with it the joy of spending time with family and the beauty of snow. However, it can also bring some discomfort, particularly for your teeth. If you’ve ever experienced tooth pain during the colder months, you are not alone. Here are some reasons why your teeth may hurt in winter and some useful tips on how to deal with it.
Temperature sensitivity
One of the most common reasons for tooth pain in winter is heightened sensitivity to temperature changes. As winter approaches and temperatures drop, many people notice an increase in tooth sensitivity, particularly when exposed to cold air or foods. This discomfort can range from a mild twinge to a sharp, lasting pain, making it an unwelcome addition to the winter chill. This sensitivity occurs when the protective enamel on your teeth wears down, exposing the dentin underneath, which contains tiny tubules leading to the nerves inside the tooth.
Causes of temperature sensitivity
Several factors can contribute to increased tooth sensitivity during colder months, these can include: –
- Enamel Erosion: The enamel is the protective outer layer of your teeth. Over time, it can wear down due to acidic foods, aggressive brushing, or grinding, exposing the sensitive dentin beneath.
- Gum Recession: This occurs when the gum tissue surrounding the teeth pulls back, exposing the roots. The roots lack the protective enamel, making them more vulnerable to temperature changes.
- Cracked or Damaged Teeth: Fractures or chips in teeth can expose the inner layers, leading to sensitivity in cold weather.
- Dental Procedures: Recent dental work, such as fillings or crowns, can temporarily increase sensitivity, particularly to extreme temperatures.
Sinus pressure
During winter, sinus infections and colds are more prevalent. When your sinuses become inflamed or congested, they can exert pressure on the upper teeth, leading to a dull ache or sharp pain. This is because the roots of the upper teeth and the floor of the sinuses are closely located.
Bruxism (teeth grinding)
Stress levels can increase during the holiday season, and some people unconsciously grind their teeth, a condition known as bruxism. Grinding can cause tooth pain and sensitivity due to the constant pressure and wear on the teeth.
Change in diet
Winter often brings changes in diet, with an increase of acidic sugary treats and hot beverages. These can contribute to tooth decay and increased sensitivity. Whilst sugary foods can lead to cavities, hot drinks can cause sudden temperature changes that affect sensitive teeth. Winter can also bring with it more colds and flu, which may lead us to reaching for cough sweets and syrups which are often packed with sugar, making this period very challenging for our teeth and gums.
Vitamin D deficiency
Winter can be a dull time of the year, with the sun not visible for much of it. As we get a lot of vitamin D from exposure to the sun, this can be a problem for our teeth as this is an important vitamin for them. Do try to get out when the sun is shining but it may also be worth considering taking a vitamin D supplement at least throughout the autumn and winter months.

Preventive measures
To alleviate winter tooth pain, consider the following tips:
Use a toothpaste for sensitive teeth
These toothpastes can help block the tubules in the dentin, reducing sensitivity and contain ingredients that blocks the pain sensors that respond to heat, cold, and sugar. There are a few different ingredients that are used in sensitive teeth toothpastes, such as:
Potassium nitrate, Fluoride or Strontium chloride.
These ingredients, when the toothpaste is used regularly over time, will help the nerves in your teeth build up a resistance to aggravators like cold, heat, and sugar. The toothpaste needs to be used daily for a few weeks to be effective.
Depending on the severity of your sensitivity, your dentist may recommend an application of fluoride to the surface of sensitive teeth will strengthen the enamel, guarding against sensitivity from exposed dentin.
Practice good oral hygiene
We can’t say this enough! Maintaining good dental hygiene is crucial for overall health and well-being. Good oral care helps prevent cavities, gum disease, and other dental issues, and contributes to fresh breath and a brighter smile. Here are some essential tips for practicing excellent teeth hygiene:
- Daily Brushing
Brush Twice a Day: It is important to brush your teeth at least twice a day, in the morning and before bed. - Use the Right Technique: Hold your toothbrush at a 45-degree angle to your gums and use gentle, circular motions. Avoid harsh scrubbing, which can damage enamel and irritate gums. Contrary to popular belief there is no need to brush vigorously to
remove stains on your teeth. In fact, too much force can weaken your enamel and wear it away. - Choose the Right Toothbrush: Use a soft-bristled toothbrush that fits comfortably in your mouth. Consider an electric toothbrush for more efficient cleaning.
- Replace Your Toothbrush Regularly: Change your toothbrush every 3-4 months or sooner if the bristles become frayed.
Stay hydrated
While there are various causes and treatments for teeth sensitivity, one often overlooked solution is staying adequately hydrated. Proper hydration plays a crucial role in maintaining oral health. Here is how staying hydrated can help reduce teeth sensitivity:
Saliva production
Adequate water intake helps in maintaining sufficient saliva production. Saliva is essential for:
- Neutralising acids produced by bacteria in the mouth
- Washing away food particles and debris
- Providing minerals like calcium and phosphate that help strengthen tooth enamel
Preventing dry mouth
Dry mouth can exacerbate tooth sensitivity by reducing saliva production, which in turn can lead to an increase in oral bacteria and acid levels. Drinking enough water helps keep your mouth moist, reducing the risk of further enamel erosion.
Visit your dentist regularly
Routine check-ups can catch problems early and help you maintain optimal dental health and regular dentist visits are essential in managing and preventing teeth sensitivity. By detecting issues early and providing personalised care, dentists can help maintain your oral health and reduce discomfort. Always consult with your dentist if you experience persistent sensitivity, as it may be a sign of a more serious underlying condition.
