Are Your Braces Triggering Your Canker Sores?

It’s Time To Love Your Smile

  • Dr. Garcia
  • October 16, 2019

blog-featured-image-braces-causing-canker-soresA few weeks into orthodontic treatment, you notice a tingling or burning sensation in your mouth. A few days later, canker sores appear. Fortunately, canker sores are not often a serious issue, but they sure can be annoying! These small ulcers can pop up in your mouth and on the inside of your lips and take days to heal. However, they are quite easy to prevent, especially once you understand what triggers them!

Braces and Canker Sores

The unfortunate news is that braces can contribute to canker sores. This mainly happens in patients that are already prone to canker sores. They may experience an increase in sores because the mouth is adjusting to a big change when beginning orthodontic treatment. Braces can irritate oral tissue, which leaves it vulnerable to tiny lesions to form, such as canker sores.

Luckily, avoiding possible triggers and practicing good oral hygiene can help you to avoid or lessen the instances of canker sores.

Common Triggers to Avoid Canker Sores

  • Stress – Stress is known to weaken your immune system, which makes it easier for canker sores to form. Make sure you’re keeping your stress at a healthy level in order to avoid canker sores!
  • Tissue Injury – Cuts or scrapes inside of your mouth can make you more vulnerable to canker sores.
  • Foods – Avoid foods that are high in acidity such as lemons, pineapples, and tomatoes, as they can trigger canker sores.
  • Sickness – You have a higher chance of getting a canker sore when infection is present in your body.

Knowing what triggers canker sores for you makes them easier to avoid. If your braces are irritating your mouth, don’t hesitate to have the spots checked out and/or ask for more dental wax.

You can also modify your oral care routine to help eliminate instances of canker sores.

  1. Rinse your mouth each day with saltwater
  2. Using a soft-bristled toothbrush will help to avoid irritating oral tissue
  3. Also, try using a toothpaste that doesn’t contain sodium lauryl sulfate

Talk to Orthodontist Dr. Francisco Garcia

If your canker sores are still persisting, be sure to speak to schedule an appointment at Garcia Orthodontics to see if there is anything else we can do to help. Whether that be a clinical rinse or gel that can provide you with relief, your smile is our priority.

Jessy is absolutely the best. She always takes amazing care of my son and does it with a genuine smile and such positive energy. It’s clear she truly cares, and that means everything to a parent. We’re so grateful to have her.

Finishing my orthodontic treatment with Nory felt like closing a long chapter and stepping into a completely new one. What started as something that seemed intimidating and slow turned into a process I’m genuinely grateful for. Nory made every appointment feel easy, explaining what was happening and why, so I never felt confused or left in the dark. Over time, I could actually see the gradual shift—small adjustments adding up to a huge transformation. The day everything finally came off felt surreal. It wasn’t just about straighter teeth; it was about confidence, patience, and seeing how consistency pays off. Walking out of that final appointment, I felt proud of the commitment I had made and incredibly thankful for how smooth and supportive the whole experience was.
