Spring is a beautiful time of year, but for many people, it also means allergy season. Along with sneezing, itchy eyes, and a runny nose, allergies can sometimes affect your dental health in ways you might not expect. If you’re experiencing tooth pain, dry mouth, or bad breath this season, it could be a sign of a true dental issue, or your spring allergies could be to blame.

Sinus Pressure and Tooth Pain

When your sinuses become inflamed due to pollen or other allergens, they can fill with mucus and cause pressure. Since the upper back teeth are located close to the sinus cavities, this pressure can sometimes feel like a toothache. If you notice a dull ache in your upper molars, especially on both sides of your face, allergies could be the cause—not a cavity.

Dry Mouth

Allergy medications, especially antihistamines, can reduce saliva production, leading to dry mouth. Saliva is important because it helps wash away food particles and neutralize acids in your mouth. Without enough saliva, you may be more prone to bad breath, cavities, and gum disease. Drinking more water, using sugar-free gum, or a mouth rinse designed for dry mouth can help keep your mouth more comfortable.

Post-Nasal Drip and Bad Breath

Another side effect of allergies is post-nasal drip, where mucus drains from the sinuses into the throat. This can create an unpleasant taste and also lead to bad breath. Good brushing and flossing habits, along with staying hydrated, can help manage these symptoms.
