As the weather starts to become colder, many people who have sensitive teeth experience some discomfort or even irritation because their teeth become sensitive to the cold. To protect your teeth from this sensitivity, consider these five tips:

1. Visit Your Dentist: If you notice that your teeth are sensitive to the cold, it's important not to assume that this is normal as it could indicate an underlying problem, such as a cracked tooth or weakened tooth enamel. This will need to be checked out by a dentist to determine what needs to be done to correct the problem so that the sensitivity no longer occurs and whatever underlying problem there is will be fixed before it becomes worse. 
2. Brush Your Teeth Gently: One reason people have teeth that are sensitive to the cold is because they brush too hard. When you brush too hard, it can cause slight abrasions on the teeth that expose the underlying nerves, which is why your teeth feel sensitive to the cold. You should even consider changing your toothpaste if brushing more gently doesn't make a difference. You should choose a desensitizing toothpaste that should help a bit. 
3. Keep Drinking Water: Water intake during the winter tends to dwindle compared to the summer season. However, it's important to continue drinking water during the winter because it will keep your teeth healthy. It keeps saliva production healthy, which is important for washing away food and bacteria in the mouth. If you experience tooth sensitivity in the winter, it could be because you are not drinking enough water to help with saliva production, which could mean that bacteria in your mouth is causing the irritation. 
4. Limit Time Outside: During the winter, if you experience sensitive teeth, you may want to limit the time you spend outside. Not only will this prevent you from getting sick because of the cold, but it can help you keep your teeth sensitivity at bay. If you do need to go outside, you may consider wearing a scarf tightly around your neck to prevent your teeth from experiencing cold. 
5. Avoid Acidic Foods: Acidic foods are already bad enough for your teeth. However, it's even worse during the winter because it damages the enamel, which exposes the nerves. This is what causes the sensitivity in the cold weather that you may not experience when eating acidic foods in the summer. 

When you utilize these five tips, you can easily protect yourself from tooth sensitivity during the winter season.
