Oral health and HAE: What you need to know
Fact-checked by Hereditary angioedema (HAE) is a condition that causes recurring episodes of swelling, most commonly affecting the face (including the eyes, lips, mouth, and tongue), airway, limbs, and intestines.
Sometimes swelling occurs without a clear cause. Other times, it can be triggered by physical injury or emotional stress. Because dental care can involve both physical stress to the body and anxiety for some people, dental visits are a known trigger for HAE attacks.
For this reason, it’s important to understand what to expect and how to manage flare-ups if you have a dental appointment scheduled.
How HAE affects the mouth and face
HAE is typically caused by genetic mutations that lead the body to overproduce an important molecule called bradykinin.
Normally, this molecule regulates blood pressure and inflammation, among other things. In people with HAE, excess bradykinin causes fluid to leak from blood vessels and collect in nearby tissues, leading to swelling.
When HAE affects the mouth and face, it can cause sudden facial swelling that may be very noticeable and sometimes painful. Swelling in the lips, cheeks, jaw, or mouth can make it harder to speak, chew, or eat, and such episodes may occur without warning or after exposure to a known trigger.
Swelling can also affect the tongue or throat. While this is less common, it may cause changes in your voice or difficulty swallowing or breathing. Being aware of these signs and monitoring any unusual symptoms can help you and your healthcare team respond quickly if care is needed.
Dental care as a trigger for HAE attacks
There are very specific dental triggers for angioedema, including procedures like dental impressions and wisdom tooth removal. These types of procedures have been known to trigger HAE swelling, which most often occurs within 48 hours of the dental work.
In addition to the physical effects of dental procedures, being aware of stress as an HAE trigger is helpful. Some studies have found that emotional stress (like anxiety around visiting the dentist) is the most common trigger factor for HAE flare-ups.
For this reason, you may want to discuss the use of sedation to reduce your anxiety and alleviate discomfort or pain during a procedure.
How to prepare for dental visits when you have HAE
It’s important not to put off dental care because of concerns about HAE attacks. Taking a proactive approach can help you get the care you need while reducing your risk of swelling.
This begins with selecting a dentist who is familiar with HAE or is willing to collaborate with your medical team to discuss potential risks and precautions.
Asking the right questions ahead of your appointment can also help you feel more prepared and supported. Consider discussing the following with your healthcare provider and dental team:
- Do I need preventive (short-term) treatment before this dental procedure?
- Which dental procedures are higher risk for triggering an HAE attack?
- Should I consider conscious sedation to help manage my anxiety?
- Should I bring my on-demand medication to the appointment, and how should it be used if symptoms start?
- How long after dental work should I watch for symptoms, and what signs should prompt action?
- What should my emergency plan be if I develop swelling?
You might also want to consider asking your healthcare team whether they can communicate directly with your dentist regarding your HAE care plan.
Everyday oral care tips for people with HAE
Maintaining good oral health can help prevent dental problems and reduce the need for more invasive dental procedures in the future.
Preventive dental care for HAE is similar to oral care recommendations for the general population: Brush and floss regularly, use interdental brushes or mouthwash as needed, and schedule routine dental visits.
Depending on your specific needs and oral health, your dentist may recommend additional precautionary measures.
When oral swelling becomes an emergency
Oral or throat swelling can sometimes become serious for people with HAE, so it’s important to know the signs that require immediate attention.
During or after dental procedures, watch for swelling in the face, lips, tongue, or throat, as well as changes in your voice, difficulty speaking, or trouble breathing or swallowing. If any of these symptoms occur, seek medical care immediately by contacting your doctor or visiting the emergency department.
Your dentist can help reduce these risks by performing the least invasive procedures necessary and monitoring for signs of swelling during treatment.
Ultimately, with the right planning and support from your healthcare team, you can manage your oral health and HAE safely and effectively.
