Top 3 Quickest Ways to Heal Canker Sores at Home – Must-Know Tips!

Canker sores, also known as aphthous ulcers, are small but painful sores that develop inside the mouth—often on the inner cheeks, lips, tongue, or gums. Although they are not contagious, they can make everyday activities like eating, drinking, and talking uncomfortable.

The good news is that many canker sores heal within 7–10 days, and there are several simple remedies you can try at home to reduce pain and speed up healing. Below are the top 3 quickest and most effective home treatments that many people find helpful.

1. Salt Water Rinse

Salt water is one of the simplest and most effective remedies for canker sores. It works by helping to clean the wound, reduce bacteria in the mouth, and promote faster healing.

How to use it

1. Dissolve 1 teaspoon of salt in a cup of warm water.

2. Swish the solution around your mouth for 20–30 seconds.

3. Spit it out and repeat 2–3 times per day.

Why it works

Salt has natural antiseptic properties, which can help prevent infection and reduce inflammation around the sore.

⚠️ You may feel a slight stinging sensation at first, but this usually fades quickly.

2. Baking Soda Paste

Baking soda (sodium bicarbonate) helps neutralize acids in the mouth, reduce irritation, and create a healthier environment for healing.

How to use it

1. Mix 1 teaspoon of baking soda with a few drops of water.

2. Stir until it forms a thick paste.

3. Apply the paste directly onto the sore using a clean finger or cotton swab.

4. Leave it on for 1–2 minutes, then rinse your mouth.

Repeat this 1–2 times daily for best results.

Why it works

Baking soda can help balance oral pH levels and soothe irritated tissues, which may shorten the healing time.

3. Honey Application

Honey is a powerful natural remedy known for its antibacterial, anti-inflammatory, and healing properties.

How to use it

1. Dab a small amount of pure honey directly onto the canker sore.

2. Let it sit for several minutes before swallowing or rinsing.

3. Apply 3–4 times per day, especially before bedtime.

Why it works

Honey helps keep the sore moist and protected, which may reduce pain and promote faster tissue repair.

In addition to the remedies above, these habits can make a big difference in how quickly your mouth heals:

Avoid irritating foods

Stay away from:

• Spicy foods

• Acidic fruits like oranges and pineapples

• Salty snacks

• Crunchy foods that may scrape the sore

Use a soft toothbrush

A soft-bristled toothbrush can prevent further irritation to the affected area.

Stay hydrated

Manage stress

Stress is a common trigger for canker sores. Relaxation techniques like deep breathing or short walks may help reduce flare-ups.

A healthcare professional can check for underlying issues such as vitamin deficiencies, hormonal changes, or immune conditions.
