Relief for Canker Sores
Canker sores are small, round, ulcerated sores that appear, often two or three at a time, on the inside of lips and cheeks and on tongues, palates, and gums. Although their cause is unknown, they often occur after tissue abrasions from braces or ill-fitting dentures, tissue injuries such as bitten cheeks or lips, and ingestion of citric fruits. They generally disappear without scars after two weeks but often return a few times each year. They are not contagious and afflict only half of all people for whom they are merely a painful annoyance and do not require professional attention.
Most mild cases heal on their own, but ongoing or severe outbreaks should not be ignored. At Highbridge Dental Associates, we provide supportive care, evaluation, and treatment when canker sores become recurrent, unusually painful, or persistent. Our goal is to help reduce discomfort, promote healing, and rule out underlying concerns that may be contributing to irritation.
When Canker Sores Need Professional Care
In some instances, however, canker sores pose greater risk and professional assistance is necessary. You should promptly seek care if:
- You experience canker sores for the first time
- Your canker sores are large (almost one half inch in diameter), extremely painful, and scarring
- Your afflictions become more frequent
- Your canker sores become more numerous
- Your canker sores last longer than two weeks
- Rashes, joint pain, fever, or diarrhea accompany your canker sores
Recurring sores may signal irritation from dental appliances, nutritional deficiencies, immune conditions, or other health concerns. A professional evaluation ensures proper diagnosis and relief.
Symptoms
Typical symptoms include a round, shallow ulcer with a white or yellow center and a red border. Many patients notice a tingling or burning sensation one to two days before the sore appears. Eating acidic or spicy foods may increase pain during flare-ups. Although discomfort is temporary for most individuals, recurring outbreaks can affect eating, speaking, and daily comfort.
Keeping track of triggers and noting frequency helps guide your dentist in forming an effective management plan.
Canker Sore Treatment
We will carefully examine your canker sores and may provide you with prescription gels and/or creams that will mitigate their pain, deter their growth, and accelerate their healing.
During your visit, we may also:
- Recommend protective wax or appliance adjustments if irritation is due to braces or dentures
- Suggest mouth rinses or sensitivity-soothing solutions to reduce inflammation
- Discuss nutritional or lifestyle factors that may play a role
- Evaluate for underlying conditions when sores present with systemic symptoms
Our goal is to reduce discomfort quickly and help you heal efficiently while preventing recurring irritation when possible.
Schedule Your Visit
Avoiding acidic foods, maintaining gentle brushing habits, and managing irritation from appliances can reduce outbreaks. Staying hydrated, managing stress, and using soft-bristle toothbrushes may also support oral comfort over time.
If recurring or painful canker sores are affecting your quality of life, Highbridge Dental Associates can help you find relief and healing support. Contact us today to schedule an evaluation and receive guidance tailored to your symptoms and comfort.
Frequently Asked Questions
Are canker sores the same as cold sores?
No. Cold sores are caused by a virus and appear outside the mouth, while canker sores appear inside and are not contagious.
Can certain foods trigger canker sores?
Yes. Citrus, acidic foods, and some spices can irritate tissues and may trigger outbreaks in sensitive individuals.
Do canker sores always need treatment?
Mild sores usually heal on their own, but large, painful, or frequent sores benefit from professional care.
Can stress contribute to flare-ups?
Stress and fatigue are known factors that may increase irritation or frequency for some patients.
