Yes, allergies can contribute to teeth grinding, also known as bruxism. Several studies and articles suggest a link between allergies and this condition.
The Connection Between Allergies and Teeth Grinding
Several mechanisms explain this connection:
-
Postnasal drip: Allergies often lead to postnasal drip, causing excess mucus in the back of the throat. The act of swallowing this mucus can trigger jaw clenching, potentially leading to teeth grinding, especially at night (nocturnal bruxism). [Source: Hollymead Dental Arts]
-
Histamine release: Allergic reactions trigger the release of histamine. This chemical can stimulate the muscles in your jaw, leading to clenching and grinding. [Source: TeethNightGuard.com]
-
Eustachian tube swelling: Allergic rhinitis (inflammation of the nasal passages) can cause swelling of the Eustachian tubes in the ears. This may indirectly contribute to chronic teeth grinding. [Source: Smiles Dentistry 4 Kids]

Increased prevalence in allergic children: A University of Miami School of Medicine study found a significantly higher prevalence of nocturnal bruxism in children with allergies compared to their non-allergic peers. This strongly suggests a correlation. [Source: Provided text]
Types of Bruxism and Allergic Links
While the connection between allergies and bruxism is evident, it's crucial to note that bruxism manifests in different forms:
- Nocturnal bruxism: Grinding or clenching teeth during sleep, commonly linked to allergies due to the nighttime swallowing of postnasal drip.
- Diurnal bruxism: Grinding or clenching during waking hours; the link to allergies might be less direct but still possible through stress or discomfort from allergy symptoms.
It is important to consult a dentist or allergist if you suspect allergies are contributing to your bruxism. They can help diagnose the cause and recommend appropriate treatment. While allergies might be a contributing factor, they are not the sole cause in most cases. Other factors, such as stress and sleep disorders, also play significant roles.
