Why Do My Teeth Hurt When I Have a Cold?
It is common for patients to experience tooth pain when they have a cold and wonder if it is a dental problem. At a dental clinic, this is a question we hear often.
Tooth pain during a cold can feel alarming, but in many cases, the teeth are not the real cause. Understanding the connection between your teeth and sinuses helps you know when the pain is temporary and when a dental check-up is needed.

Why Does a Cold Affect My Teeth?
A cold causes changes in your nose and sinuses that can lead to tooth discomfort.
Common reasons include
- blocked or stuffy nose
- sinus congestion
- inflammation of sinus lining
- pressure on nearby tooth nerves
That is why the pain often feels dull, aching, or spread across several teeth.
Which Teeth Usually Hurt?
Most often, the pain is felt in
- upper molars
- upper premolars
Lower teeth are usually not affected by sinus-related tooth pain.
Other Reasons Teeth May Hurt During a Cold
While sinus pressure is the main cause, there are other factors that can add to the discomfort.
Sinus Infection
If a cold lasts longer or becomes severe, it may turn into a sinus infection.
Signs include
- thick nasal discharge
- facial pain
- pressure around eyes and cheeks
- worsening tooth pain
Jaw Clenching or Grinding
When you are unwell, stressed, or sleeping poorly, you may clench or grind your teeth without realising.
This can cause
- tooth soreness
- jaw pain
- headache
Cold Sensitivity
During a cold, you may breathe more through your mouth. This exposes your teeth to cold air, which can trigger sensitivity, especially if enamel is already weak.
Existing Dental Problems
A cold can make existing issues more noticeable, such as
- cavities
- gum inflammation
- cracked teeth
The pain may seem related to the cold, but the tooth itself may need treatment.
How to Know If Tooth Pain Is From a Cold or a Dental Problem
Sinus-related tooth pain usually
- affects multiple upper teeth
- feels like pressure or dull pain
- worsens when bending forward
- improves as the cold improves
Dental pain usually
- affects one tooth
- feels sharp or throbbing
- hurts while chewing
- continues even after the cold is gone
What Can I Do to Relieve Tooth Pain During a Cold?
Simple steps can help reduce discomfort.
Relieve Sinus Pressure
- inhale steam
- use saline nasal spray
- stay well hydrated
- take warm showers
Reduce Inflammation
- rest properly
- use a warm compress on cheeks
- follow medical advice for cold relief
Avoid Cold Triggers
- avoid very cold drinks
- breathe through your nose when possible
- keep your mouth covered in cold air
Maintain Oral Care
- brush gently
- do not skip flossing
- use a soft toothbrush
When Should I See a Dentist?
You should see a dentist if
- tooth pain lasts after your cold is gone
- pain is sharp or severe
- swelling appears in gums or face
- chewing causes pain
This helps rule out cavities or infections.
Dental Advice to Manage Tooth Pain During a Cold
While recovering from a cold, dentists commonly advise patients to
- maintain gentle brushing and flossing
- avoid very cold or hard foods
- use a soft toothbrush
- stay hydrated
Managing nasal congestion also helps reduce pressure on dental nerves.
When a Dental Visit Is Recommended
Patients should consult a dentist if
- tooth pain persists after cold recovery
- pain is sharp or increasing
- there is swelling in the gums or face
- chewing causes discomfort
Early dental assessment helps prevent complications and ensures proper treatment.
Why Dental Evaluation Matters
Sinus pain and dental pain can feel very similar. A dental examination ensures
- accurate diagnosis
- early detection of dental issues
- appropriate treatment planning
This protects both oral health and overall comfort.
Final Thoughts
If you are wondering “Why do my teeth hurt when I have a cold?”, the answer is usually sinus pressure, not a dental problem.
The pain often goes away as the cold improves. However, if it does not, or if the pain feels different or intense, a dental checkup is important.
Understanding the cause can help you stay calm, manage the discomfort, and know when to seek care.
