How Seasonal Allergies Can Affect Your Oral Health (And What to Do About It)

How Seasonal Allergies Can Affect Your Oral Health (And What to Do About It)

Seasonal allergies are a common struggle, especially in spring and fall. While most people associate allergies with sneezing, watery eyes, and congestion, they can also have surprising effects on your oral health.

1. Dry Mouth and Allergies

Allergies often lead to postnasal drip, which can cause mouth breathing—especially during sleep. Mouth breathing dries out the oral cavity and reduces saliva flow. Since saliva is essential for washing away bacteria and neutralizing acids, a dry mouth can lead to:

2. Tooth Pain or Pressure

Sinus congestion from seasonal allergies can create pressure in your upper jaw. This often results in a dull, aching sensation in your upper molars, mimicking a toothache. If your tooth pain coincides with allergy season and is generalized (rather than focused on one tooth), it’s likely sinus-related.

3. Medications and Oral Health

Many allergy medications, especially antihistamines, cause dry mouth as a side effect. This worsens the natural dryness caused by allergens and increases your risk of cavities and plaque buildup.
