Can Allergies Affect Your Teeth

When you think of allergies, sneezing, watery eyes, and itchy skin might be the first symptoms that come to mind. However, have you ever stopped to consider the connection between your allergies and your dental health? It's a question many of us have overlooked, but the answer is surprising.

Allergies and Dental Health

Seasonal allergies are the body's heightened response to environmental triggers present during specific times of the year. This overreaction involves the immune system releasing chemicals, which can lead to symptoms like congestion and post-nasal drip, among other things. Common culprits behind these reactions are pollen from trees, grasses, and weeds.

At first glance, it might seem unlikely that something like seasonal allergies could influence the health of your teeth or gums. However, allergies can indirectly lead to a variety of oral health concerns. Let's explore this hidden connection in a little more detail.

Mouth Breathing and Dry Mouth

Many allergy sufferers find themselves breathing through their mouths due to nasal congestion. You may not even notice you are doing it since this may often happen at night while you sleep. This might seem harmless, but prolonged mouth breathing can result in dry mouth.

Without the regular flow of saliva to cleanse the mouth, bacteria thrive. These things can increase the risk of tooth decay, gum disease, and bad breath.

Swollen Gums

Post-nasal drip, common among allergy sufferers, involves excess mucus accumulating at the back of the nose or throat, often leading to throat clearing, coughing, and soreness. This mucus, produced in response to allergens like pollen or dust, can indirectly impact dental health.

Mucus contains proteins that oral bacteria thrive on and also bacteria of its own. Over time, this (especially when combined with dry mouth) can irritate and inflame the gums, paving the way for gingivitis. Another unfortunate side effect of swollen or painful gums can be a reluctance to brush and floss thoroughly. And we all know this can lead to tooth decay and gum disease.

Medications and Oral Health

Antihistamines are a common go-to for many individuals to combat allergy symptoms. However, they can have the side effect of reducing saliva production, leading to dry mouth. Just as with mouth breathing, reduced saliva can pave the way for bacterial growth.

Sinus Pressure and Tooth Pain

When the sinuses become congested due to allergies, it can lead to pressure in the upper jaw. This pressure can sometimes cause discomfort or pain in the molars. While this doesn't directly harm the teeth, let's face it: tooth and jaw pain are uncomfortable and can be disruptive.
