Seasonal allergies can be an annual annoyance for many, causing sneezing, itchy eyes, and congestion. But did you know that these allergies could also impact your oral health?

While most people associate allergies with respiratory symptoms, they can also have surprising effects on your teeth and gums. Recognizing these issues can help you take  steps to protect your smile during allergy season.

How Seasonal Allergies Can Impact Oral Health

Seasonal allergies happen when your immune system overreacts to allergens like pollen, dust mites, or grass. While the connection between allergies and sinus congestion is well-documented, the effects on your teeth and gums often go unnoticed.

From sinus pressure to the ingredients in allergy medications, several factors can affect the health of your mouth.

Toothaches from Sinus Congestion

One of the most common oral health complaints during allergy season is tooth pain, which is often linked to sinus congestion.

Your sinus cavities (a normal part of your anatomy, unlike cavities that can occur in teeth) sit right above your upper molars. When allergies cause your sinuses to swell, the added pressure can create discomfort that feels very similar to a toothache. This pain is generally dull and affects multiple teeth, making it easy to confuse with a dental issue.

How to Manage It:

• Stay Hydrated: Drinking a sufficient amount of water can thin the mucus in your sinuses and help relieve pressure.
• Use a Saline Rinse: A saline nasal spray can reduce sinus inflammation and keep passages clear.
• See Your Dentist: If pain persists or is limited to one tooth, it may not be sinus-related. A dental visit can rule out the possibility of cavities or infections.

Dry Mouth

Another common issue during allergy season is dry mouth. This can be caused by several factors, including mouth breathing (when congested) and the use of antihistamines. Less saliva can make it difficult to wash away bacteria and food particles, increasing the risk of cavities and gum disease.

How to Manage It:

• Chew Sugar-Free Gum: This helps stimulate saliva production and keeps your mouth moist.
• Stay Hydrated: Sipping water throughout the day keeps your mouth hydrated and reduces the feeling of dryness.
• Avoid Caffeine and Alcohol: These can exacerbate dry mouth symptoms.
• Use a Mouthwash for Dry Mouth: Over-the-counter rinses specifically designed for dry mouth can be a helpful addition to your routine.

Swollen Gums

Allergy-related inflammation doesn’t just affect your nasal passages; it can extend to your gums as well. When your immune system is in overdrive, it can sometimes trigger gum swelling or tenderness. This is especially likely in individuals prone to gum sensitivity or underlying periodontal issues.

Swollen gums can make it more challenging to maintain good oral hygiene, increasing the likelihood of plaque buildup.

How to Manage It:

• Stick to a Consistent Oral Care Routine: Brush twice daily and floss to minimize plaque buildup.
• Rinse with Salt Water: A simple saltwater rinse can soothe swollen gums and reduce inflammation.
• Visit Your Dentist: If swelling persists, your dentist can evaluate your gums and provide personalized treatment options.

Additional Sugar from Allergy Medications

Many over-the-counter allergy medications, especially liquid formulations designed for children, contain added sugar to improve taste. The downside? Regular exposure to sugar can increase the risk of cavities, particularly if teeth aren’t brushed soon after taking the medication.

How to Manage It:

• Look for Sugar-Free Medications: Look for sugar-free or tablet alternatives that don’t pose a risk to your teeth.
• Rinse After Medication: Encourage rinsing the mouth with water after taking liquid medications to minimize sugar exposure.
• Brush and Floss Regularly: Maintain excellent oral hygiene by brushing twice daily and flossing at least once per day.

Sore Throat

Post-nasal drip is a common symptom of seasonal allergies, where mucus from the sinuses drips down the back of your throat. This can lead to a sore, irritated throat. But did you know that post-nasal mucus can also coat your teeth, creating a breeding ground for bacteria and bad breath?

How to Address It:

• Gargle: Gargling with warm salt water can help soothe your throat and clear mucus buildup.
• Maintain Oral Hygiene: Brush and floss regularly to remove any harmful bacteria from your teeth.
• Rinse with Mouthwash: Consider an antibacterial mouthwash for extra protection.
