Braces are an incredible tool for achieving a straight, healthy smile—but they can come with a few temporary side effects, especially in the early stages. One of the most common complaints from new orthodontic patients? Canker sores.
If you or your child is dealing with small, painful ulcers inside the mouth while wearing braces, you’re not alone. These pesky sores can make eating and talking uncomfortable, but the good news is: they’re treatable, manageable, and usually temporary.
In this post, we’ll explain what causes canker sores with braces, how to treat them, and what you can do to prevent them from coming back.
What Are Canker Sores—and Why Do Braces Cause Them?
Canker sores (also called aphthous ulcers) are small, shallow lesions that appear on the soft tissues inside your mouth, such as the cheeks, lips, tongue, or gums. They’re not contagious, but they can be painful—especially when irritated by braces.
Common causes of canker sores with braces include:
- Friction from brackets or wires rubbing against the cheeks or lips
- Accidental biting of the inside of the mouth
- Stress or minor mouth trauma
- Sensitivity to certain foods (like acidic fruits or spicy snacks)
While they’re more common during the first few weeks after getting braces, they can pop up any time there’s irritation in the mouth.
How to Treat Canker Sores From Braces
Most canker sores heal on their own within 7–10 days, but there are ways to reduce pain and speed up the healing process:
1. Rinse With Salt Water or a Mild Antiseptic Mouthwash
A warm saltwater rinse (1 tsp of salt in 1 cup of water) can reduce inflammation and help keep the sore clean. Use 2–3 times per day.
2. Apply Orthodontic Wax
Place a small piece of wax over any bracket or wire that’s causing friction. This acts as a barrier between your braces and the inside of your mouth.
3. Use Over-the-Counter Treatments
Topical gels like benzocaine (e.g., Orajel or Anbesol) can numb the area and provide temporary relief.
4. Avoid Irritating Foods
Stay away from acidic, spicy, or crunchy foods while the sore is healing. Stick to soft, bland options like yogurt, smoothies, and soups.
5. Stay Hydrated and Maintain Oral Hygiene
Drinking plenty of water and keeping your mouth clean helps prevent infection and promotes faster healing.
When Should You See Your Orthodontist or Dentist?
While most canker sores go away on their own within a week or two, there are times when it’s best to check in with a professional. If a sore lasts longer than two weeks, becomes unusually large or painful, or is accompanied by symptoms like a fever or swollen lymph nodes, it could indicate something more serious. In these cases, your orthodontist or dentist can evaluate the sore, rule out other issues, and recommend a stronger or prescription treatment if needed.
Preventing Canker Sores While Wearing Braces
Although it’s not always possible to completely avoid canker sores during orthodontic treatment, there are several habits that can help reduce the likelihood of developing them.
Regular use of orthodontic wax can create a protective barrier between your brackets and the inside of your mouth, minimizing irritation. Brushing gently with a soft-bristled toothbrush also helps keep your mouth clean without aggravating sensitive areas. Avoiding sharp or crunchy foods—like chips or crusty bread—can prevent accidental trauma, and staying consistent with your orthodontic checkups ensures wires and brackets are adjusted properly to reduce rubbing and pressure over time.
As your mouth adapts to braces, canker sores typically become less frequent and easier to manage.
