Why do my teeth hurt in cold weather?

Tooth sensitivity in winter

Do your teeth suddenly ache when you step into the crisp, cold air? Or perhaps they feel unusually tender whenever you enjoy the comforting warmth of your favourite hot chocolate?

If cold weather makes your teeth hurt, you’re not alone. This common issue often stems from sensitivity to temperature, which can be exacerbated during the chilly months.

In this blog, we’ll explore why your teeth might feel more sensitive during the winter and share tips for protecting your smile while it’s frosty outside.

Why do my teeth hurt in cold weather?

Your teeth can be sensitive to temperature changes due to the intricate network of nerves and blood vessels inside them. When exposed to cold air or drinks, these nerves can react, leading to discomfort and pain. Common reasons for winter tooth sensitivity include:

Worn tooth enamel

Your enamel is the outer protective layer of your teeth, acting as a barrier against temperature extremes. Over time, factors like acidic foods, aggressive brushing or teeth grinding can erode this enamel, leaving the underlying dentin exposed and leading to sensitivity.

Gum recession

As gums recede, they expose the roots of your teeth, which lack the protective enamel that crowns the rest of the tooth. This exposure increases sensitivity to cold air and drinks. Gum recession can result from periodontal disease, aggressive brushing or natural ageing.

Tooth decay

Cavities create tiny openings in your teeth, allowing cold temperatures to reach the sensitive inner layers. If your teeth are aching in the winter, it might be time to check for signs of decay.

Cracks or chips

Cracks or chips in your teeth create pathways for temperature changes to reach the nerves inside. These small imperfections may not be noticeable until you experience discomfort from the cold.

Bruxism (teeth grinding)

Grinding or clenching your teeth can wear down enamel and increase sensitivity. Bruxism often worsens during stressful times – such as the busy festive season.

How to protect your teeth during the winter

If the cold weather has you wincing, there are some steps you can take to manage and prevent sensitivity.

Use a toothpaste for sensitive teeth

Desensitising toothpaste contains compounds that block nerve signals, reducing sensitivity over time. Look for a fluoride toothpaste designed for sensitivity, and use it regularly for the best results.

Switch to a soft-bristled toothbrush

Aggressive brushing with a hard-bristled toothbrush can damage your enamel and irritate your gums. Opt for a soft-bristled toothbrush and use gentle, circular motions when brushing.

Protect against gum recession

Keep your gums healthy by maintaining good oral hygiene. Brush twice a day, make sure to floss and visit our Chatham dental practice regularly so that we can monitor your gum health.

Avoid acidic foods and drinks

Acidic substances, like vinegar and fizzy drinks, can erode enamel and worsen sensitivity. Limit your intake and rinse with water after consuming these items to minimise their effects.

Keep hydrated

Saliva helps to neutralise acids and protect your teeth. Stay hydrated by drinking plenty of water throughout the day, especially if you’re prone to dry mouth.

When to see our Chatham dentists

If your teeth hurt persistently in cold weather, or if the pain is severe, please contact our Chatham dental practice as soon as possible. Call us on 01634 756536. Sensitivity can sometimes indicate an underlying issue that requires treatment, such as tooth decay, gum disease, exposed tooth roots or cracked or damaged teeth. Our dentists can diagnose the cause of your sensitivity and recommend treatments that will relieve your discomfort and restore your smile.

The best way to avoid winter tooth sensitivity…

…is to maintain good oral hygiene all year round. Simple habits, like brushing twice daily with fluoride toothpaste, flossing and attending regular dental check-ups, go a long way in protecting your teeth from sensitivity and decay. Caring for your teeth now means you can enjoy this winter without any unwelcome discomfort.

Will my tooth sensitivity go away on its own?

Tooth sensitivity can sometimes clear up on its own, but if it sticks around for more than a day or two, it’s time to see our Chatham dentists. Sensitivity can indicate a larger problem that needs to be addressed. Many of our patients complain of tooth sensitivity during the colder months, but don’t brush it off! Delaying your visit gives any hidden oral health issues time to worsen.
