Cold weather can affect your daily oral hygiene habits and make existing dental sensitivity more noticeable. When temperatures drop in Bells Corners and Ottawa, you may experience discomfort while breathing in cold air, drinking hot beverages, or moving between warm indoor spaces and the outdoors.
Although cold weather does not directly cause every dental problem, seasonal changes can highlight underlying concerns such as sensitive teeth, worn enamel, gum recession, or cracked teeth. Changes in eating habits, hydration, and oral care routines can also influence your dental health during winter.
The good news is that a few consistent habits can help you protect your teeth and gums throughout the colder months.
At Robertson Family Dentistry, patients in Bells Corners and the surrounding Ottawa area can seek guidance on maintaining their oral health throughout the year. Understanding how winter conditions affect your teeth can help you recognize potential concerns and know when to speak with a dental professional.
How Does Cold Weather Affect Your Teeth?
Cold weather can affect your teeth in several ways. Some people notice increased sensitivity when going outside, while others experience discomfort when consuming hot or cold foods and drinks.
The effects depend on your oral health, existing dental conditions, and daily habits.
1. Increased Tooth Sensitivity
Tooth sensitivity is one of the most noticeable dental concerns during winter.
When protective enamel becomes worn, or the gums recede, the underlying dentin may become exposed. Dentin contains microscopic channels that can transmit sensations toward the inner part of the tooth.
Cold air, cold drinks, and temperature changes may then trigger a sharp or brief sensation.
Common signs of tooth sensitivity include:
- A sharp sensation when drinking cold water
- Discomfort when eating ice cream
- Sensitivity to hot coffee or tea
- Pain when breathing through your mouth in cold air
- Discomfort when brushing certain teeth
If sensitivity is persistent, affects one particular tooth, or becomes more severe, consider arranging a dental examination.
2. Dry Mouth During Winter
Cold weather can change how you hydrate throughout the day. Indoor heating may also make the air feel dry, and some people drink less water during winter than they do in warmer months.
A dry mouth occurs when there is not enough saliva to keep the mouth comfortably moist.
Saliva plays an important role in oral health because it helps wash away food particles, neutralize acids, and support the mouth’s natural protective processes.
A dry mouth may contribute to:
- An uncomfortable or sticky feeling
- Difficulty swallowing dry foods
- Bad breath
- An increased risk of tooth decay
- Irritation of the mouth and gums
To support saliva production, drink water regularly and maintain your usual oral hygiene routine. If dry mouth persists, discuss it with your dentist or healthcare professional, especially if you take medications that may contribute to dryness.
3. Cracked or Damaged Teeth
Cold weather itself does not necessarily crack healthy teeth. However, an existing crack or weakened tooth may become more noticeable when exposed to temperature changes or pressure during chewing.
You may notice:
- Pain when biting down
- Sensitivity to hot or cold foods
- Intermittent discomfort
- A sharp sensation when chewing on one side
Avoid chewing hard foods with a tooth that hurts, and arrange an examination if you suspect a crack.
A dentist can assess the tooth and discuss appropriate treatment options based on the extent of the damage.
7 Practical Ways to Protect Your Teeth in Cold Weather
Protecting your teeth during winter does not require a complicated routine. Consistent oral hygiene, mindful food choices, and attention to new symptoms can help support your dental health.
1. Brush Twice a Day With Fluoride Toothpaste
Continue brushing your teeth twice daily with fluoride toothpaste, including throughout winter.
Fluoride helps strengthen tooth enamel and supports the prevention of tooth decay.
For effective brushing:
- Use a soft-bristled toothbrush.
- Brush gently for two minutes.
- Clean the front, back, and chewing surfaces of your teeth.
- Pay attention to the gumline.
- Avoid brushing with excessive pressure.
Brushing too aggressively can contribute to gum irritation and wear around the exposed tooth surface.
If you experience sensitivity while brushing, consider a toothpaste designed for sensitive teeth and discuss persistent symptoms with your dentist.
2. Clean Between Your Teeth Every Day
Brushing alone cannot clean every surface between your teeth.
Food particles and plaque can accumulate in areas that a toothbrush may not reach. Cleaning between your teeth helps remove this buildup and supports gum health.
Depending on your needs, you may use:
- Dental floss
- Interdental brushes
- Other interdental cleaning tools recommended by your dental team
Choose a method that suits your teeth and gums, and use it consistently throughout the year.
3. Protect Sensitive Teeth From Cold Air
If cold air makes your teeth uncomfortable, try breathing through your nose when practical rather than directly through your mouth.
When spending time outdoors in Bells Corners or Ottawa during colder weather, covering your mouth with a scarf can help warm the air you breathe.
You can also reduce exposure to triggers that cause discomfort, such as very cold drinks.
These measures may help reduce symptoms, but they do not address every possible cause of sensitivity. If discomfort continues, a dental assessment can help determine whether treatment is needed.
4. Choose Tooth-Friendly Foods and Drinks
Winter often brings changes in eating habits. Food and drinks that can affect your teeth like Hot chocolate, sweetened coffee, holiday treats, and sugary snacks may become more frequent.
Frequent exposure to sugar can increase the risk of tooth decay because oral bacteria use sugars to produce acids that attack enamel.
To support your teeth:
- Choose water regularly throughout the day.
- Limit frequent sugary snacks.
- Enjoy sweet treats with meals rather than grazing on them throughout the day.
- Include a variety of nutritious foods in your diet.
- Be mindful of the sugar content in hot drinks.
You do not need to avoid every seasonal treat. Paying attention to how often you consume sugary foods and drinks is an important part of maintaining good oral health.
5. Drink Water Regularly
It is easy to overlook hydration during winter because you may not feel as thirsty as you do in summer.
However, maintaining adequate hydration supports normal saliva production and helps keep your mouth comfortable.
Make water a regular part of your day, especially if you spend long periods in heated indoor environments.
If you frequently experience dry mouth despite drinking water, ask your dental or healthcare professional whether another factor could be contributing to the problem.
6. Avoid Using Your Teeth to Open Packages
During winter, people often handle packaging, snack containers, and holiday gifts. Avoid using your teeth to open wrappers, tear plastic, or bite through hard materials.
Your teeth are designed for chewing food, not for opening objects.
Using them as tools can increase the risk of chips, cracks, and damage to existing fillings or crowns.
If you notice a chipped tooth, avoid placing excessive pressure on the affected area and contact a dental professional for advice.
7. Keep Up With Regular Dental Checkups
Your teeth and gums still need attention during winter, even if you are busy with work, family activities, or seasonal travel.
Regular dental examinations allow your dental team to assess your oral health and identify concerns that may need further evaluation.
Depending on your individual needs, your appointment may include an examination of your teeth and gums, an assessment of existing restorations, and recommendations for preventive care.
If you have been postponing an appointment, winter can be a useful opportunity to review your oral health routine.
Can Cold Weather Cause Toothaches?
Cold weather does not necessarily cause a toothache, but low temperatures can make existing dental sensitivity more noticeable.
A toothache may be associated with several conditions, including:
- Tooth decay
- Exposed dentin
- Gum recession
- A cracked tooth
- A damaged filling
- Inflammation around the tooth
- A dental infection
For example, if a tooth already has a cavity or a crack, exposure to cold air or drinks may trigger discomfort.
Pay attention to the pattern of your symptoms. Brief sensitivity affecting several teeth may have a different cause from persistent pain in one tooth.
However, symptoms alone cannot establish a diagnosis.
If tooth pain continues, becomes severe, or interferes with eating or sleeping, contact a dental professional for assessment.
What Should You Do if Your Teeth Hurt in Winter?
If you notice tooth pain or sensitivity during colder weather, start by identifying what seems to trigger it.
Consider the following steps:
- Notice the trigger. Does discomfort occur with cold air, hot drinks, cold water, or chewing?
- Avoid unnecessary irritation. Temporarily limit foods and drinks that consistently cause discomfort.
- Maintain gentle oral hygiene. Continue brushing with fluoride toothpaste and cleaning between your teeth.
- Avoid self-diagnosis. Sensitivity may have several causes, so do not assume that every symptom is harmless.
- Arrange a dental examination when appropriate. Persistent or worsening symptoms should be assessed.
Avoid placing aspirin or other medications directly on your teeth or gums. Follow medication instructions and consult a pharmacist or healthcare professional if you are unsure what is appropriate for you.
When Should You See a Dentist for Cold-Weather Tooth Sensitivity?
Consider contacting a dentist if you experience:
- Tooth sensitivity that continues or becomes more frequent
- Sudden pain affecting one tooth
- Pain when biting or chewing
- Sensitivity that lingers after exposure to hot or cold
- A cracked, chipped, or damaged tooth
- Swelling around the gums or face
- Pain that interrupts sleep
Facial swelling accompanied by difficulty breathing or swallowing requires emergency medical attention.
If you are experiencing a suspected dental infection or significant swelling, seek prompt professional care rather than waiting for your symptoms to improve.
Winter Oral Care for Families
Cold weather can affect the daily routines of adults and children alike. Maintaining consistent oral hygiene habits can help every family member protect their teeth.
For Children
Encourage children to:
- Brush twice daily with age-appropriate fluoride toothpaste.
- Clean between their teeth when appropriate.
- Drink water regularly.
- Avoid chewing ice or other hard objects.
- Tell a parent if they experience tooth pain or sensitivity.
Parents should pay attention to complaints about pain when eating, drinking, or brushing.
If a child’s tooth becomes painful or damaged, arrange an appropriate dental assessment.
For Adults
Adults can support their oral health by maintaining their regular hygiene routine, limiting frequent sugary snacks, and addressing habits such as teeth grinding.
If you use a night guard or another dental appliance, follow the cleaning and care instructions provided by your dental professional.
People with existing dental restorations, gum recession, or a history of sensitivity may benefit from discussing winter-related symptoms with their dentist.

Frequently Asked Questions About Protecting Your Teeth in Cold Weather
Cold air can trigger discomfort when dentin is exposed because of enamel wear or gum recession. Cold-weather tooth pain may also be associated with decay, cracked teeth, or other dental conditions. Persistent symptoms should be evaluated by a dentist.
Cold weather can make tooth sensitivity more noticeable, but it is not necessarily the underlying cause. Exposed dentin, gum recession, enamel wear, cavities, and damaged teeth are among the possible reasons for sensitivity.
Brush twice daily with fluoride toothpaste, clean between your teeth, drink water regularly, limit frequent sugary snacks, and avoid using your teeth to open objects. If cold air triggers sensitivity, breathing through your nose when practical and covering your mouth outdoors may help.
Sensitivity to hot and cold can be associated with exposed dentin, gum recession, enamel erosion, tooth decay, cracked teeth, or other dental concerns. A dental examination can help determine the cause.
Dry mouth can contribute to a higher risk of tooth decay because saliva helps neutralize acids and wash away food particles. Staying hydrated may help, but persistent dry mouth should be discussed with a dental or healthcare professional.
Some people experience brief sensitivity when breathing in cold air, particularly if dentin is exposed. However, recurring or severe discomfort should not automatically be considered normal. A dentist can evaluate the symptoms.
A toothpaste formulated for sensitive teeth may help reduce sensitivity for some people. Choose a product appropriate for your needs, use it as directed, and consult your dentist if symptoms continue.
Yes, sudden sensitivity—especially when it affects one tooth, causes pain when biting, or continues after exposure to a trigger—deserves attention. It may be associated with decay, a crack, gum recession, or another dental concern.
Hot drinks do not automatically damage healthy teeth when consumed at comfortable temperatures. However, very hot beverages can burn oral tissues, and frequent sugary drinks can contribute to tooth decay. Let very hot drinks cool before consuming them.
Winter does not automatically change how often you need dental examinations. The appropriate interval depends on your oral health, risk factors, and your dentist’s recommendations.
Avoid triggers that worsen the pain, maintain gentle oral hygiene, and contact a dental professional if the pain persists or becomes severe. Swelling, suspected infection, or significant dental damage may require prompt attention.
A cracked tooth may be sensitive to temperature changes or pressure during chewing. If you suspect a crack, avoid chewing hard foods with that tooth and arrange a dental examination.
