More than half of the global population has some kind of allergy. It could be because of dust or even certain foods. But do you know that we can face toothache due to allergy? Let us look at what dental problems can we face due to allergies and how to tackle them.

Do you have any allergies? 

Allergic rhinitis also known as hay fever is a type of inflammation in the nose that usually occurs when the immune system responds to the allergens in the air.

The condition is generally triggered by environmental allergens such as pollen, pet hair, dust or mould. The inherited genetics and environmental conditions can also contribute to the development of allergies.

Symptoms of allergies are

  1. Clogged or runny nose
  2. Sneezing
  3. Breathlessness
  4. Itchy, red and watery eyes
  5. Swelling around eyes and on the face

Toothache due to allergy

When your body is allergic to dust or pollen, you’re likely to develop mucus in your sinuses. Eventually, bacteria multiply and lead to more production of mucus. Maxillary sinuses (the largest sinus) are located above the upper back teeth and transmits the pressure onto the teeth. 

The patient may experience sensitivity to hot and cold substances and notices a dull pain. It alleviates more when you bend forward. 

Dry mouth

If you suffer from any allergy, your mouth may become dry. It happens during nose blockage that you are forced to breathe through your mouth.

A dry mouth boosts dental issues including bad breath, gum disease, and even cavities. An insufficient amount of saliva in the mouth during allergies trigger the bacteria in the mouth.


When children have a chronic allergic reaction, they usually become mouth breathers. This can alter the physiological balance of growth and lead to disturbance in the development of occlusion

What you can do to avoid toothache due to allergy?

  1. Stay hydrated: A dry mouth acts as a trigger for the oral microbes, leading to damage to your teeth. It can also help flush away the excess mucus.
  2. Gargle with salt water: Dissolve a tablespoon of salt in a glass of warm water and gargle for 2-3 minutes. Salt helps to draw mucus out of your sinuses and relieve your symptoms.
  3. Brushing and flossing is the key: Even if you have an allergic attack, your oral hygiene will keep you away from all the dental problems.
  4. Treat your allergies: Consult with your doctor about treating allergies.
  5. Regular visits to the dentist: If you experience any pain or discomfort, talk to your dentist and get it treated.
