Canker Sores
Canker Sore Treatment in Toledo, OH
Our team helps patients find fast, effective relief from painful canker sores. If a sore in your mouth is making it hard to eat, drink, or talk comfortably, we’re here to help.
What is a Canker Sore?
A canker sore is a small, shallow ulcer that forms inside the mouth — usually on the inside of the cheeks or lips, the tongue, or the base of the gums. Unlike cold sores, canker sores are not contagious and don’t appear on the outside of the mouth. They typically show up as a white or yellow center surrounded by a red, inflamed border, and can range from mildly irritating to quite painful.
What Causes Canker Sores?
Canker sores can be triggered by a variety of factors, including:
- Minor injury to the mouth (biting your cheek, aggressive brushing, dental work)
- Stress or lack of sleep
- Certain foods, especially acidic or spicy items
- Vitamin deficiencies (B12, folate, iron, or zinc)
- Hormonal changes
- Toothpaste containing sodium lauryl sulfate (SLS)
- Underlying health conditions affecting the immune system
If you notice canker sores appearing frequently, it may be worth discussing your diet, oral care routine, and overall health with our team.
Signs to See a Dentist for Canker Sores
Most canker sores heal on their own within one to two weeks. However, you should schedule a visit with our office if you experience:
- A sore that lasts longer than two weeks
- Sores that are unusually large or keep spreading
- Severe pain that over-the-counter treatments don’t relieve
- Frequent, recurring canker sores
- Sores accompanied by fever or other symptoms

Canker Sore vs. Cold Sores
These two are commonly mixed up, but they’re quite different:
Canker Sores:
- Occur inside the mouth, not contagious, not caused by a virus
- Often linked to stress, minor injury, certain foods, or vitamin deficiencies
- Heal within 7 to 14 days, no scarring
Cold Sores:
- Appear on or around the lips, contagious, caused by the herpes simplex virus
- Often start with tingling before a blister forms and scabs over
- Can recur during stress, illness, or sun exposure
Knowing which one you have matters — cold sores are contagious and may call for antiviral treatment, while canker sores don’t spread and are managed differently. If you’re unsure which type you have, our team can help identify it and recommend the right care.
Home Care Tips for Canker Sore Relief
While you wait for a sore to heal, these tips can help ease discomfort:
- Rinse with warm salt water or a baking soda rinse
- Avoid spicy, acidic, or rough-textured foods
- Use a soft-bristled toothbrush
- Try an over-the-counter oral gel for pain relief
- Avoid picking at or irritating the sore
Frequently Asked Questions
How Long Do Canker Sores Usually Last?
Most canker sores heal on their own within 7 to 14 days. If a sore lasts longer than two weeks, it is a good idea to have it checked by a dentist.
Are Canker Sores Contagious?
No. Unlike cold sores, canker sores are not caused by a virus and cannot be spread through kissing, sharing utensils, or other contact.
What Is the Fastest Way to Get Rid of a Canker Sore?
While there is no instant cure, rinsing with warm salt water, avoiding acidic or spicy foods, and using an over-the-counter oral gel can speed up healing and ease pain. Persistent or severe sores may benefit from a prescription treatment from our office.
Why Do I Keep Getting Canker Sores?
Frequent canker sores can be linked to stress, vitamin deficiencies such as B12 or iron, certain toothpaste ingredients, or an underlying health condition. If they keep coming back, our team can help identify possible triggers.
Should I See a Dentist for a Canker Sore?
Most sores do not require a dental visit, but you should schedule an appointment if a sore is unusually large, lasts more than two weeks, keeps recurring, or comes with a fever or other symptoms.
Can Children Get Canker Sores?
Yes, canker sores are common in both children and adults. If your child has a recurring or unusually painful sore, our pediatric dental team can help.
