The Link Between Oral Health and Allergies

As flowers bloom and days grow warmer, we know summer is near. But for many, it also marks the return of seasonal allergies — and their effects go beyond sneezing and congestion. Allergies can impact your oral health, too.

In this blog post, we’ll explore the connection between allergies and oral health, and share tips to protect your smile during allergy season.

How Seasonal Allergies Impact Your Oral Health

Seasonal allergies are triggered by allergens like pollen, dust mites, and mold spores. When exposed, your immune system releases histamines, causing inflammation in the sinuses, nasal passages, and even affecting your mouth.

Here’s how allergies can impact your teeth and gums:

• Dry Mouth: Many allergy medications, especially antihistamines, can cause dry mouth. Saliva protects your teeth; without enough, you’re at higher risk for cavities, gum disease, and bad breath. 
• Sinus Pressure and Tooth Pain: Congested sinuses, especially the maxillary sinuses, can create pressure that feels like a toothache — particularly in the upper back teeth. It’s important to distinguish this from true dental issues. 
• Mouth Breathing: Nasal congestion often leads to mouth breathing, which dries out the mouth and increases the risk of tooth decay and gum inflammation. 
• Postnasal Drip: Excess mucus can irritate the throat and contribute to mouth breathing, indirectly encouraging bacterial growth and plaque buildup in the mouth. 
• Sore Throat: Constant throat irritation might make swallowing uncomfortable and promote mouth breathing, further drying oral tissues. 

Tips for Maintaining Oral Health During Allergy Season

While allergies can pose some challenges, a few simple steps can keep your smile healthy:

• Stay Hydrated: Drink plenty of water to help counteract dry mouth. Limit sugary and acidic drinks, which can worsen enamel erosion and cavities. 
• Practice Good Oral Hygiene: Brush at least twice a day, floss daily, and consider using an antibacterial mouthwash to reduce bacteria buildup. 
• Rinse Your Sinuses: Use a saline nasal spray or rinse to help clear allergens and reduce sinus pressure. This can ease oral discomfort caused by sinus congestion. 
• Choose Allergy Medications Wisely: Some medications cause less dry mouth than others. Speak with your doctor or pharmacist about the best options for you. 
• Visit Us at Oliver Park Dental Regularly: Routine dental checkups at our Edmonton clinic are key to spotting and addressing problems early.
