Toothache during a cold: causes, symptoms and ways to relieve pain

Many people notice toothache during a cold or flu, even if their teeth were previously symptom free. Pressure in the upper jaw, pulling discomfort in the lower jaw or aching molars are common. Often, no dental disease is present. Instead, irritated sinus cavities, sinusitis, bronchitis or a corona infection can trigger or intensify pain in teeth, jaw joints and surrounding tissue.

At a glance:

• Toothache during colds often results from swollen sinuses, pressure in the maxillary sinuses and temporarily sensitive teeth.
• One sided or persistent symptoms may indicate a separate dental condition.
• Gentle measures can relieve symptoms; fever, swelling or chills require medical evaluation.

What toothache during a cold, flu or corona infection feels like

Typical signs include pressure in the upper jaw, aching back teeth, discomfort when bending forward or a combination of tooth and ear pain. Some people describe pain in the temporomandibular joint or pulling sensations in the underjaw.

Common search phrases include “toothache with a cold”, “toothache with flu”, “toothache and corona infection”, “lower jaw pain during a cold” or “molars hurting with a cold”. All reflect the close link between respiratory infections and dental discomfort.

How toothache develops during a cold

Sinusitis and pressure in the maxillary sinuses

When the paranasal sinuses or maxillary sinuses are inflamed, pressure builds up and can affect the roots of the upper jaw teeth. This leads to upper jaw pain, toothache related to sinus pressure and the feeling that several teeth hurt at once.

Pain when blowing the nose, bending forward or with vibration

Rapid pressure changes – blowing the nose, coughing or descending stairs – often intensify symptoms. Short, stabbing sensations or enhanced pressure in the upper jaw are common.

Sensitive teeth during a cold

Cold air, dry mucous membranes and mouth breathing make exposed tooth surfaces more reactive. As a result, even mild stimuli can feel painful.

Bronchitis, flu and corona

Fever, chills and general illness can heighten pain perception. Some patients report stronger toothache during bronchitis, flu or corona infection.

When a dental condition is the real cause

Caries, inflamed nerves and gum disease

Onesided, throbbing or persistent pain may indicate a dental disease. Caries, inflamed pulp or gum infection can overlap with cold symptoms.

Root canal treatment, dental surgery and wisdom teeth

Questions often arise around treatment: Is a root canal advisable with a cold? What if you catch a cold after tooth extraction? What about removing wisdom teeth while sick? Because the body is weakened, healing may be slower and discomfort stronger.
‍

Jaw joint strain and radiating pain

Coughing, clenching or tension can strain the temporomandibular joint. Pain may radiate to the ear or lower jaw.

What helps? Practical measures to relieve symptoms

Simple steps at home

Hydration, humidified air, inhalation and a slightly elevated head position reduce sinus pressure. Gentle oral care and avoiding sudden head movements help prevent pain flares.
‍

Medication

Ibuprofen or paracetamol relieve discomfort temporarily; decongestant nasal sprays reduce sinus pressure and can indirectly ease toothache.

Protecting teeth, gums and jaw

Use a soft toothbrush and fluoride toothpaste. Avoid very hard foods and unnecessary jaw strain.

When to see a dentist or ENT specialist

Seek professional help if:

• Pain is severe, onesided or throbbing
• Swelling occurs
• Fever or chills accompany toothache
• Pain worsens after dental surgery
• Symptoms persist after the infection has resolved
