Remedies for toothache caused by cold air: myth or truth?

“A draft gave me a toothache” or “My tooth hurts because of cold air” are common explanations for sudden dental pain. Whether it involves sitting near an open window, exposure to air conditioning, or cold temperatures, drafts are often blamed for toothaches, sometimes accompanied by pain in the ear or cheek area.

But from a medical point of view, is there such a thing as a ‘draught affecting the teeth’? According to specialists, there is no evidence that mere exposure to cold air is a cause of toothache. Instead, contact with cold air can trigger pain when a tooth is already sensitive or affected by a dental problem.

The link between cold and toothache often arises simply by coincidence: the discomfort occurs during or shortly after exposure to cold air, and the patient assumes that this is the cause of the pain.

In reality, some dental problems can develop without obvious symptoms, and the pain may occur suddenly, giving the impression that it was caused by an external factor. That is why it is important not to automatically attribute the pain to a draught, but to identify the underlying cause.

Thus, the pain commonly attributed to ‘a draught’ may, in reality, have causes such as:

• tooth sensitivity;
• tooth decay;
• cracks in the teeth;
• inflammation of the dental pulp. 

Another important factor is how the pain manifests itself: whether it occurs only on contact with cold air and disappears quickly, or whether it persists, intensifies or occurs even in the absence of this stimulus. These differences can provide the dentist with important clues for making a diagnosis.

The way the pain presents itself can provide clues:

Brief, cold-induced pain: may suggest dentine hypersensitivity.
Persistent or throbbing pain: may indicate pulp involvement.
Pain on chewing or to the touch: may be associated with a crack or inflammation of the tissues surrounding the root.
Pain accompanied by swelling of the gums: requires assessment to rule out an infection.

These symptoms alone do not establish a diagnosis. The cause can only be identified through a dental consultation.

Temporarily avoiding cold air and very cold foods

Temporarily protecting your teeth from cold air and avoiding very cold drinks can reduce discomfort.

However, this measure only relieves the symptoms; it does not treat the underlying cause.

Using a toothpaste for sensitive teeth

Desensitising toothpastes contain ingredients that can reduce the transmission of stimuli to the sensitive structures of the tooth.

The effect usually becomes apparent with regular use. Your dentist can recommend the right product depending on the cause of the sensitivity.

Gentle and proper oral hygiene

Use a soft-bristled toothbrush and avoid applying excessive pressure whilst brushing.

Tooth sensitivity is no reason to stop looking after your teeth. On the contrary, regularly removing plaque is important for the health of your teeth and gums.

Medicines for temporary pain relief

Some painkillers can temporarily relieve pain, provided they are used in accordance with the package leaflet and taking any contraindications into account.

Do not delay seeing a dentist simply because the pain subsides after taking a medicine. Antibiotics are not suitable for all types of toothache and should only be taken on the advice of a doctor.

Some home remedies may make the discomfort worse or delay the necessary treatment.

Avoid:

• Applying aspirin directly to the tooth or gum, as this can cause damage to the mucous membrane.
• Using alcohol or other irritants on the painful area.
• Applying heat to your cheek if you suspect a dental infection.
• Taking antibiotics without medical advice.

None of these remedies is a substitute for identifying and treating the cause of the pain.

Book an appointment if the pain persists, recurs frequently or sensitivity to the cold becomes more severe.

Spontaneous pain, particularly at night, as well as the appearance of swelling or discharge, may indicate a problem requiring treatment.

A fever accompanied by facial swelling requires prompt medical assessment. If you experience difficulty swallowing or breathing, seek emergency medical assistance.

Treatment for tooth sensitivity

Depending on the diagnosis, the dentist may recommend desensitising toothpastes or professional fluoride treatments.

It is also important to identify the factors that have led to dentine exposure, in order to minimise the recurrence of sensitivity.

Treatment of tooth decay and restoration of affected teeth

If the pain is caused by a cavity, the dentist removes the affected tissue and restores the tooth, where possible.

Cracks and other dental defects require treatments tailored to their location and extent.

Root canal treatment for inflammation of the dental pulp

When the dental pulp is irreversibly damaged or infected, endodontic treatment may be necessary.

This aims to remove the affected tissue from the root canal system and preserve the natural tooth.

Treatment for gum recession

The periodontist assesses the causes of gum recession and determines the necessary measures to manage them.

Depending on the situation, treatments to reduce sensitivity in exposed roots or specific periodontal procedures may be recommended.

Prevention starts with brushing correctly, without applying excessive pressure, and using oral care products suited to your needs.

Limit your frequent consumption of acidic foods and drinks, which can contribute to enamel erosion.

Treating tooth decay and gum problems, together with regular check-ups and professional cleanings, helps to maintain good oral health.

At DENT ESTET clinics, the assessment aims to identify the cause of the pain through a clinical examination and, where necessary, imaging tests.

Depending on the diagnosis, doctors with experience in dental therapy, endodontics and periodontology may work together.

Treatment is personalised, with the aim of eliminating the cause of the pain and preserving natural teeth wherever possible.
