How to Relieve Canker Sore Pain

Canker sores can make eating, drinking, brushing your teeth, and even talking uncomfortable. Although there isn’t an instant cure, there are several ways to reduce discomfort while the sore heals naturally. Most canker sores improve on their own within one to two weeks.

Why Are Canker Sores So Painful?

Canker sores are shallow ulcers that develop inside the mouth.

Because they expose sensitive tissue, everyday activities such as eating or brushing your teeth can become uncomfortable.

The discomfort often seems worse when the sore comes into contact with:

• Spicy foods
• Acidic foods
• Salty foods
• Hot beverages
• Toothbrush bristles

Fortunately, the pain usually improves as the sore heals.

How Can You Reduce the Pain?

Although you can’t make a canker sore disappear overnight, you can often make it more comfortable while it heals.

Helpful measures may include:

• Rinsing with warm salt water
• Drinking cool water
• Eating softer foods
• Avoiding foods that irritate the sore
• Maintaining good oral hygiene

These simple steps may help reduce irritation and support healing.

Should You Keep Brushing Your Teeth?

Yes.

Continue brushing and cleaning between your teeth every day.

Good oral hygiene helps reduce bacteria in the mouth and supports overall oral health.

Brush gently around the sore using a soft-bristled toothbrush to avoid additional irritation.

Which Foods Should You Avoid?

Some foods may increase discomfort while a canker sore is healing.

You may feel more comfortable avoiding:

• Citrus fruits
• Tomatoes
• Pineapple
• Spicy foods
• Salty snacks
• Crunchy foods with sharp edges

Choosing softer, milder foods for a few days may make eating more comfortable.

Can Over-the-Counter Products Help?

Many over-the-counter products are available to help manage canker sore discomfort.

Depending on the product, they may:

• Form a protective coating over the sore
• Temporarily numb the area
• Reduce irritation while eating or drinking

Because different products work in different ways, ask your dentist or pharmacist if you’re unsure which option is appropriate for you.

Should You Pop or Scrape a Canker Sore?

No.

Trying to scrape, puncture, or remove a canker sore may increase irritation and delay healing.

Allowing the sore to heal naturally is the healthiest approach.

How Long Will the Pain Last?

For many people, discomfort is greatest during the first few days.

As healing progresses, the pain usually becomes less noticeable until the sore resolves completely.

Most canker sores heal within one to two weeks.

When Should You See a Dentist?

Although most canker sores heal on their own, you should schedule an evaluation if:

• The sore lasts longer than two weeks.
• It becomes unusually large.
• The pain continues to worsen.
• Eating or drinking becomes very difficult.
• You experience frequent outbreaks.
• You’re unsure whether it’s actually a canker sore.

We’ll evaluate the area and determine whether additional treatment or further evaluation is needed.
