In the past year, 16.9 million adults and 6.7 million children were diagnosed with seasonal allergies. One of the worst symptoms of this malady is sinus pressure. Sinuses are pockets of bone lined with mucous membranes, the most “famous” of which lie in our face. When congestion develops in our maxillary sinuses (so named for their location directly above our top molars), this puts pressure on the roots of the teeth, which can mimic a toothache. Antihistamine use may alleviate the pressure, but if the ache persists, please call our office for assistance! A common side effect of taking antihistamines is dry mouth. Since saliva is the mouth’s own cleaner, reduced amounts of it puts you at greater risk for cavities, halitosis, and gum disease.
