Asthma is a condition that you may have at the back of your mind. You might be doing your best to avoid triggering it while also being prepared to deal with any attacks if they come about. However, did you know that your oral health can be affected by it? It might seem odd, but you should make sure your smile stays in great shape for the benefit of your asthma. Here’s what you need to know and how to protect your grin.

What Can Asthma Do to Affect My Oral Health?

As you likely already know, asthma affects your breathing. When you are trying to catch your breath due to your asthma, you might experience dry mouth. You won’t be able to produce adequate levels of saliva, which can have an impact on your oral health.

Since you’ll have more trouble washing away harmful bacteria, they’ll be able to linger on your smile and attack your teeth and gums. You’ll be more likely to develop a cavity or periodontal disease. Not only that, but bad breath is also common!

Can My Asthma Medication Cause Any Issues?

During an asthma attack, you might rely on an inhaler to manage your symptoms, but these can also affect your grin. It’s estimated that 80% of the dose doesn’t actually reach your lungs. It can hang around your mouth at the base of your tongue, soft palate, tonsils, and the back of your throat. This can also lead to dry mouth or make existing dental problems worse.

However, this doesn’t mean you shouldn’t take the asthma medication you need altogether! Talking with your dentist and physician can help you find ways to ensure you avoid any complications.

How Can I Preserve My Oral Health with Asthma?

Although this condition can affect your oral health, there are ways you can prevent the harm it may do. These are some easy tips you can follow:

  • Drink Plenty of Water: This will keep your mouth moist and promote saliva production. Be sure to have a glass after using your inhaler as well.
  • Keep Up with Your Oral Hygiene: Brushing and flossing twice daily will remove bacteria from your smile.
  • Chew Sugar-Free Gum: Having some on hand will help encourage saliva production.
  • Visit Your Dentist Consistently: Letting your provider take a look at your mouth will help ensure there aren’t any problems arising. If there are, you can get the prompt treatment you need for a stronger grin.
