Ever stepped outside on a chilly morning and felt a sudden zing in your teeth? You’re not imagining it. Winter can do more than just freeze your fingers—it can cause serious discomfort in your mouth too.
If you’ve ever wondered, “Why do my teeth hurt more in winter?”, you’re not alone. Many South Africans, especially around Parktown North, experience increased tooth sensitivity and pain during cold months. And while it might seem like just another winter woe, the root of the issue (pun intended 😄) could be more serious than you think.
In this blog, we’ll break down the 7 main reasons your teeth hurt in winter, answer frequently asked questions, and give you expert solutions straight from the team at Cahi Dental Practice.
Let’s warm up to the facts 👇

🦷 Why Do Teeth Hurt More in Cold Weather?
1. Temperature Sensitivity
Cold air can cause your teeth to expand and contract, especially if they have worn enamel or exposed dentin. This movement exposes nerve endings, leading to sharp, sudden pain.
➡️ Quick Tip: Breathe through your nose and cover your mouth with a scarf when outdoors to reduce exposure.
2. Tooth Enamel Erosion
Your enamel acts like a shield. But when it’s thinned from grinding, acidic foods, or brushing too hard, your teeth become more reactive to cold air and drinks.
➡️ Did you know? Over 40% of people aged 18-44 experience enamel erosion symptoms.
3. Gum Recession
When gums pull away from the tooth’s surface, they expose the root, which isn’t protected by enamel. Cold air? Hot drinks? Pain city.
➡️ Solution: Ask your dentist about desensitising treatments or a fluoride varnish to protect roots.
4. Cracked or Damaged Teeth
Even tiny cracks in your teeth can let cold air reach the inner layers. Winter air makes this pain even worse, especially when chewing.
➡️ Pro Tip: Visit Cahi Dental Practice to check for any hidden fractures.
5. Sinus Pressure
Sinus inflammation from cold and flu season can press down on your upper molars, causing what feels like dental pain—even if your teeth are perfectly healthy.
➡️ Hack: A steamy shower or nasal spray might relieve pressure and pain.
6. Old Dental Work
Fillings or crowns made from metal expand and contract with temperature changes. This can cause discomfort around the treated tooth in winter.
➡️ Fix: Modern composite materials from clinics like Cahi Dental Practice can replace outdated fillings for better comfort.
7. Bruxism (Teeth Grinding)
Stress levels often rise in winter (yes, holiday season pressure is real!), and this can increase nighttime grinding or clenching—leading to sore teeth and jaw tension.
➡️ Relief: Ask your dentist about a custom night guard to prevent wear and reduce pain.
🧠 FAQs About Winter Tooth Pain
Q: Why are my teeth more sensitive to cold air than to cold food?
A: Cold air hits your entire mouth quickly, affecting multiple teeth at once, especially if you’re breathing through your mouth. Cold food is more targeted and temporary.
Q: Can cold weather make a tooth infection worse?
A: Absolutely. Infections can feel more painful in the cold due to nerve sensitivity. If pain persists, see a dentist immediately.
Q: Should I avoid hot drinks in winter if my teeth hurt?
A: Not necessarily. But if your teeth react to temperature changes (hot AND cold), it could signal enamel damage or deeper issues.
Q: Can I prevent winter tooth pain naturally?
A: You can reduce discomfort with good oral hygiene, using a sensitivity toothpaste, and staying warm. But if symptoms continue, always consult a professional.
🧼 How to Prevent Winter Tooth Sensitivity (Backed by Experts)
Here’s how you can protect your smile this winter:
✅ 1. Use Sensitivity Toothpaste
Brands with potassium nitrate or stannous fluoride block pain signals from the nerves in your teeth.
✅ 2. Don’t Skip Brushing (Even When It’s Cold!)
Maintaining your oral hygiene reduces the risk of gum disease and enamel erosion. Use a soft-bristle toothbrush to avoid damaging your enamel.
✅ 3. Stay Hydrated
Dry winter air and heaters can reduce saliva production, making your mouth more vulnerable. Water keeps your gums and enamel healthy.
✅ 4. Book a Dental Check-Up
If you live in Parktown North or nearby, Cahi Dental Practice offers expert evaluations, cleanings, and treatments to combat seasonal sensitivity.
✅ 5. Avoid Acidic Foods
Winter citrus treats and spicy dishes can wear down your enamel. Rinse your mouth with water after eating them.
🧊 The Bottom Line: Don’t Let Cold Weather Freeze Your Smile
Winter doesn’t have to mean wincing every time you step outside or sip on your hot chocolate. The truth is, your teeth shouldn’t hurt—regardless of the weather. If they do, it’s a sign that something’s off and it’s time to take action.
Your smile deserves protection, warmth, and attention year-round.
