Winter Tooth Sensitivity: Why Cold Makes Your Teeth Ache
James Janda • December 2, 2025
What Causes Cold Sensitivity?
December brings frosty mornings and chilly winds. Many of us experience an unwelcome seasonal companion: sensitive teeth. That sharp, sudden pain (zing!)
when breathing in cold air or sipping an iced peppermint mocha—it's your teeth telling you something needs attention.
What Causes Cold Sensitivity?
Tooth sensitivity to cold temperatures mostly happens when the inner layer of the tooth - dentin - gets exposed to the outside environment. Dentin is more porous compared to enamel - so sensations have a more direct route to the tooth's inner nerve, uninsulated.
Here are the most common culprits:
- Enamel wear - Years of acidic food, aggressive brushing, or teeth grinding can gradually erode your enamel, the tooth's protective outer shell. Once this barrier thins, temperature changes reach the sensitive dentin underneath.
- Receding Gums - When gum tissue pulls back from the tooth, it exposes the root surface, which lacks the protective enamel coating. This is increasingly common as we age and can be accelerated by gum disease (periodontitis) or by brushing too hard (abrasion).
- Cavities - Even small areas of decay can create pathways for cold sensations to reach the tooth's nerve center, causing discomfort.
- Cracked or Chipped Teeth - A tiny crack can be enough to allow cold air or liquids to penetrate deeper into the tooth structure, triggering sensitivity.
- Recent Dental Work - It's normal to experience temporary sensitivity after fillings, crowns, or teeth whitening treatments. This typically subsides within a few weeks. (If it doesn't, definitely contact your dentist.)
- Whitening Treatments - It's important to note that whitening treatments do not harm your enamel. That said, it does lower the tooth's threshold for sensitivity, especially if dentin is exposed anywhere.
Finding Relief :
Good news - Most tooth sensitivity can be managed effectively with these tips :
- Switch to Sensitivity Toothpaste (Sensodyne) - Products containing potassium nitrate or stannous fluoride work by blocking the tiny tubules in your dentin that transmit pain signals. Use it consistently for at least two weeks to see results.
- Use an Extra-Soft Toothbrush - Gentle, circular motions protect your enamel and gums better than aggressive scrubbing. Think massage, not scrape. Electric toothbrushes usually have extra-soft "sensitivity" heads you can work with as well.
- Reduce/Neutralize Acids - Limit acidic foods and beverages like citrus, soda, and wine that can erode enamel. When you do indulge, rinse your mouth with water afterward. Don't immediately brush your teeth after consuming acidic foods!
- Consider a Mouthguard - If you grind your teeth at night, a custom mouthguard can prevent further enamel wear.
- Try Fluoride Treatments - Your dentist can apply professional-strength fluoride varnishes to strengthen enamel and reduce sensitivity. Fluoride also plugs those tiny tubules that can cause dentin sensitivity.
- Stop Whitening - Whitening-related cold hypersensitivity is very temporary. Once your cease using your whitening gel or trays, your teeth should recover within 48 hours.
When You Should See Your Dentist :
While occasional cold sensitivity is common, persistent or severe pain warrants a dental visit. Your dentist can identify whether the issue is simply surface-level sensitivity, or a sign that something more serious needs treatment.
Don't let sensitive teeth keep you from enjoying winter's pleasures. With the right care and attention, you can drink that iced latte and breathe in the crisp December air without wincing. Happy Holidays!
Halloween is a favorite holiday for many families—costumes, fun, and of course, candy! But with all those sweet treats comes a higher risk for cavities and toothaches. At Prairie Point Dental, we want to help your kids enjoy the festivities while still protecting their teeth. 1. Choose “Tooth-Friendly” Candy Not all candy is created equal. Sticky or gummy candies cling to teeth and feed cavity-causing bacteria. Instead, opt for chocolate (which melts and rinses away easier) or sugar-free gum. Hard candies that stay in the mouth for long periods should also be avoided. 2. Set a Candy-Eating Time Instead of snacking on sweets throughout the day, encourage kids to enjoy their candy after a meal when saliva production is already high—this helps wash away sugar and food particles. Rinsing with water or brushing afterward can reduce acid buildup. 3. Reinforce Brushing & Flossing After Halloween night, remind kids of the importance of brushing twice a day and flossing. You might even let them pick out a fun new toothbrush to keep the excitement going. If it's been more than six months since their last checkup, now's a great time to schedule a cleaning. 4. Consider a Post-Halloween Dental Visit If you notice increased sensitivity, gum irritation, or toothaches, don't wait until it worsens. Our team is here to evaluate and treat any issues early. We also provide cosmetic whitening services if parents want to refresh their smile post-Halloween season! Let your family enjoy the spooky season without scary dental surprises. Prairie Point Dental is here to help with friendly, expert care every step of the way.
As schedules fill up with homework, sports, and after-school activities, dental checkups often fall to the wayside. But maintaining routine visits for every family member—kids and adults alike—can help prevent larger problems down the road. At our practice, we strive to make full-family dental care easy, convenient, and as hassle-free as possible. So, that being said - why should you re-prioritize your child's routine dental exams, when school is just around the corner? 1. Prevention is Simpler (and Cheaper!) Than Treatment Seeing the dentist every six months can catch early signs of cavities, gum issues, or misaligned teeth—long before they become painful or costly. Children especially benefit from early detection - small baby teeth with larger pulp chambers can become toothaches quickly, making school days difficult for the kids to sit through. Also - checkups and cleanings usually bear smaller fees than multiple fillings or pulpotomies, making it a much more appealing choice for your budget. 2. Identify Orthodontic Needs While Children are Still Growing For adolescents, the school year is a smart time to start thinking about orthodontic care. As kids grow up, their baby teeth give way to adult dentition that can become crowded due to not having enough room. To make room, orthodontic treatment can be recommended, and the younger the patient is when their needs are identified, the better the treatment outcome will be (bone is much more flexible and receptive to changes when the child is still growing). We shouldn't miss out on finding those needs early! 3. Reduces Dental Anxiety by Familiarizing Children with a Dental Environment Having a routine, uneventful dental exam and cleaning is a great way for children to build a sense of safety and assuredness in medical environments, and can greatly reduce anxiety in the future, should they ever need dental treatment. Our providers are great with kids of all ages , and we always strive to deliver a calm, clean, and kind environment that rewards children for showing independence and bravery. Parents can model for their children by coming in routinely to their own visits, and this helps kids grow into responsible patients as adults. Are you or your children due for a checkup?
