Allergies and Oral Health: What You Need to Know

As the seasons change, many of us experience the familiar symptoms of allergies—sneezing, congestion, itchy eyes, and sometimes even dry mouth. While these symptoms can be bothersome, it’s important to understand how allergies can also affect your oral health. Here’s what you need to know to keep your mouth healthy during allergy season.

1. Dry Mouth and Cavities

One of the most common side effects of allergies is a dry mouth, often caused by mouth breathing or the use of antihistamines. A dry mouth occurs when there is a lack of saliva, which is essential for washing away food particles and neutralising acids produced by bacteria. Without sufficient saliva, you may be at a higher risk of developing cavities, bad breath, and even gum disease.

What You Can Do:

• Stay hydrated by drinking plenty of water throughout the day.
• Chew sugar-free gum to stimulate saliva production.
• Consider using a humidifier at night to add moisture to the air, especially if you breathe through your mouth while sleeping.

2. Sinus Pressure and Tooth Pain

Allergies can cause your sinuses to become inflamed and congested, leading to pressure that sometimes manifests as tooth pain. This is especially common in the upper molars, which are close to the sinuses. If you experience sudden tooth pain during allergy season, it may not be a dental issue but rather sinus-related.

What You Can Do:

• Use a saline nasal spray to help relieve sinus congestion.
• Apply a warm compress to your face to reduce sinus pressure.
• If the tooth pain persists, visit us to rule out any potential dental problems.

3. Increased Risk of Gum Disease

Allergies and their associated symptoms can contribute to gum inflammation. For instance, frequent sneezing and mouth breathing can lead to dry and irritated gums, which may become more susceptible to gum disease over time.

What You Can Do:

• Maintain a consistent oral hygiene routine, including brushing twice a day and flossing daily.
• Rinse your mouth with a fluoride mouthwash to help strengthen your gums.
• If you notice persistent gum irritation or bleeding, schedule a visit with us for an evaluation.

4. Post-Nasal Drip and Bad Breath

Post-nasal drip, a common symptom of allergies, occurs when mucus accumulates at the back of your throat. This can lead to bad breath, as bacteria in your mouth break down the mucus and produce unpleasant odours.

What You Can Do:

• Stay on top of your oral hygiene by brushing your teeth, tongue, and the roof of your mouth regularly.
• Use an antibacterial mouthwash to help control the bacteria responsible for bad breath.
• Drink plenty of water to help thin the mucus and reduce post-nasal drip.

5. Managing Allergy-Related Oral Health Issues

The key to managing oral health during allergy season is to stay proactive. By recognising the connection between your allergies and oral health, you can take steps to prevent potential issues before they arise.
