Can Allergies Make Your Teeth Hurt

Can Allergies Make Your Teeth Hurt?

Allergies are a common issue that many people deal with, especially during high-pollen days. But did you know that these allergies can cause nasal congestion, a runny nose, and oral pain?

This blog post will explore the question: “Can allergies make your teeth hurt?”

Why Do Allergies Make Your Teeth Hurt?

During allergy season, the body’s immune response can lead to an inflammatory reaction in your nasal passages. This can cause excess mucus production, leading to sinus congestion. The maxillary sinuses, located directly above your upper teeth, can become inflamed, causing pressure that may result in tooth pain. This is a common symptom that many people experience during an allergic reaction.

In some cases, if you have a food allergy, consuming the food you’re allergic to may cause your mouth to swell and result in sensitive teeth.

Allergy Symptoms

Allergy symptoms related to toothache are primarily a result of inflammation and pressure in the sinus cavities, which are located close to the roots of your upper teeth. Here are some symptoms you might experience:

  • Tooth Pain: This is usually felt in the upper back teeth closest to the sinus cavities. The pain can be sharp, throbbing, or a dull ache, and it can sometimes be mistaken for a tooth infection.
  • Increased Tooth Sensitivity: Allergies can cause inflammation in the tooth roots, increasing sensitivity to hot, cold, or sweet foods and drinks.
  • Jaw Pain: The pressure and inflammation caused by allergies can also lead to discomfort or pain in the jaw, as the sinuses are located close to the temporomandibular joint (the joint that connects your jaw to your skull).
  • Facial Pain or Pressure: Along with tooth and jaw pain, you may also experience general discomfort or pressure in your face, especially around your nose and eyes.
  • Headache: Sinus headaches, caused by the increased pressure in the sinus cavities, can also occur. These are often felt in the forehead, cheeks, and behind the eyes.
  • Bad Breath: Postnasal drip, a common symptom of allergies where mucus drains down the back of the throat, can cause bad breath.
  • Dry Mouth: Allergies can cause dry mouth either directly by causing inflammation that blocks the salivary glands or indirectly by using antihistamines, which can reduce saliva production.

If you’re experiencing these symptoms and suspect they’re related to allergies, it’s essential to consult with your healthcare provider. While treating allergies can often alleviate these symptoms, ruling out dental problems causing your toothache is crucial.

Can Seasonal Allergies Affect Your Teeth?

Yes, seasonal allergies can affect your teeth. When your nasal passageways are blocked due to allergies, you might resort to mouth breathing, leading to dry mouth. Saliva plays a crucial role in maintaining oral health by washing away food particles and preventing bacterial buildup, which can lead to gum disease and tooth decay. A dry mouth environment can increase the risk of these dental issues.

Furthermore, postnasal drip, another symptom of allergies, can contribute to bad breath and sore throat. If left untreated, this can lead to more serious oral health issues.

Connection Between Allergies and Dental Pain

Can allergies make your front teeth hurt? Allergies can cause dental pain due to the close proximity of the sinus cavities to the mouth area. Here’s a more in-depth look at this connection:

  • Sinus Pressure: When allergies trigger inflammation and swelling in the sinus cavities, it can increase pressure. The maxillary sinuses, located directly above the upper molars, are particularly susceptible. If these sinuses become congested or inflamed, it can cause discomfort or pain in the upper teeth, often mistaken for a toothache.
  • Referred Pain: The nerves in the upper jaw are closely interconnected with those of the sinus cavities. This means that pain originating from the sinuses can be ‘referred’ or felt in the teeth, causing what feels like a toothache.
  • Jaw and Facial Pain: The pressure and inflammation caused by allergies can also lead to general discomfort or pain in the face and jaw. This is because the sinuses are located close to the temporomandibular joint (the joint that connects your jaw to your skull), and any inflammation can put pressure on this joint, causing pain.
  • Dry Mouth: Allergies can also cause dry mouth either directly by causing inflammation that blocks the salivary glands or indirectly by using antihistamines, which can reduce saliva production. A dry mouth can make your mouth uncomfortable and increase your risk of dental problems like tooth decay and gum disease.
  • Postnasal Drip: Allergies can cause a postnasal drip, where excess mucus production leads to a constant flow of mucus down the back of the throat. This can lead to a sore throat and discomfort in the mouth and throat area.

In these cases, treating the underlying allergies with antihistamines, nasal sprays, or other allergy medications can often alleviate the dental pain. However, if the pain persists, it’s important to consult a dentist to rule out any dental problems.

Managing Allergy-Related Tooth Pain

Can Allergies Make Your Teeth Hurt?

To effectively manage allergy-related tooth pain, you can consider the following options:

  • Use a Nasal Spray: This helps reduce nasal congestion and postnasal drip, alleviating the pressure on the sinuses.
  • Increase Fluid Intake: Drinking plenty of water can help soothe a dry mouth and ensure a moist environment for oral health.

For more severe cases, there are additional measures that could be taken, such as:

  • Allergy Shots or Medications: These can be recommended by an allergy specialist to reduce the severity of your allergic reactions.
  • Allergy Testing: This can help identify specific environmental allergies, such as pollen from trees, dust mites, and pet dander, that may be causing your allergic reactions.

The Role of Dental Care in Managing Allergies

Maintaining good dental care is crucial in managing the effects of allergies. Here are some steps you can take:

  • Regular Brushing and Flossing: This can remove excess mucus and food particles, reducing the risk of tooth decay and gum disease.
  • Regular Dental Check-Ups: Visiting a qualified dentist regularly helps check for any dental discomfort or potential dental procedures needed, such as root canals. This is especially important if you experience chronic sinusitis or discolored mucus, which could indicate an infected tooth.


So, can allergies cause your teeth to hurt? The answer is yes. However, with proper management and good dental care, these symptoms can be alleviated. If you or your children with allergies are experiencing sore teeth, it’s important to seek medical and dental advice to ensure healthy teeth and overall well-being during the allergy season.

Remember, the real culprit behind your tooth pain might not be a cavity or infection but could be your body’s response to allergens. So, next time you experience tooth pain during a high pollen count or exposure to indoor allergens, consider whether your allergies might be the cause.

Consult a medical and dental professional today to address your tooth pain caused by allergies and ensure your dental health and overall well-being during allergy season.
