Mouth sores are a common problem that can affect people of all ages. Whether you have a canker sore, a cold sore, or another type of lesion, these tiny but painful areas can make eating, drinking, and even speaking uncomfortable. Fortunately, several home remedies for mouth sores can help relieve pain and accelerate the healing process. Sunshine Dentistry in Richmond Hill, Ontario, believes in providing our patients with the knowledge they need to care for minor oral issues at home while also knowing when to seek professional assistance.
What Are Mouth Sores?
Mouth sores are small ulcers or lesions that appear inside the mouth, on the gums, tongue, lips, or the inner lining of the cheeks. The most common types are:
- Canker sores: Small, round, non-contagious ulcers that appear inside the mouth.
- Cold sores: Blister-like lesions usually found on or around the lips, caused by the herpes simplex virus. These are contagious.
- Other mouth sores: These can result from trauma, irritation, allergic reactions, or even systemic health conditions.
Most mouth ulcers are harmless and will heal within one to two weeks, but they can be uncomfortable in the meantime. That is why many people seek out effective home remedies for mouth sores to alleviate symptoms and promote healing.
Effective Home Remedies for Mouth Sores
If you’re looking for relief from mouth sore discomfort, try these tried-and-true home remedies for mouth sores:
1. Salt Water Rinse
A salt water rinse is a traditional and simple home remedy for mouth sores. Salt is a natural disinfectant that can help alleviate inflammation. Dissolve one teaspoon of salt in a cup of warm water, swish the solution in your mouth for 15–30 seconds, and spit it out. Repeat several times a day as needed.
2. Baking Soda Rinse
A baking soda rinse is also a practical option. Baking soda helps to neutralize acids in the mouth and can provide soothing relief for mouth ulcers. Mix one teaspoon of baking soda with half a cup of warm water, rinse, and spit it out.
3. Honey Application
Honey is widely recognized for its natural antibacterial and healing properties. Applying a small dab of honey directly to the mouth sore several times a day can help reduce pain and may speed up healing.
4. Milk of Magnesia
Over-the-counter milk of magnesia can be used to coat and protect mouth sores from further irritation. Apply a small amount to the sore three to four times daily for relief.

5. Ice Chips
Allowing ice chips to dissolve slowly in your mouth is another simple home remedy for mouth sores. The cold numbs the area, relieving pain and swelling.
6. Aloe Vera Gel
Aloe vera is famous for its soothing and healing effects. Applying a small amount of pure aloe vera gel to a mouth sore can relieve irritation and aid in the healing process.
7. Avoiding Trigger Foods
Certain foods can aggravate mouth sores and delay healing. Spicy, acidic, salty, or rough-textured foods should be avoided while the sore heals. Opt for soft, bland foods instead.
8. Maintaining Good Oral Hygiene
Keeping your mouth clean is critical when dealing with sores. Brush gently with a soft-bristled toothbrush and avoid harsh mouthwashes with alcohol. This prevents infection and helps the healing process.
When to See a Dentist for Mouth Sores
While most home remedies for mouth sores are safe and effective in minor cases, it is sometimes necessary to see a dentist. Seek professional care if:
- The mouth sore lasts longer than two weeks without improvement.
- The pain is severe or interferes with eating and drinking.
- You have frequent outbreaks of mouth sores.
- Sores are unusually large or spreading.
- You notice other symptoms, such as fever, swollen lymph nodes, or a rash
- There are signs of infection, like pus, spreading redness, or swelling.
Persistent or recurring sores may indicate an underlying health condition, such as a vitamin deficiency, autoimmune disorder, or oral cancer. At Sunshine Dentistry in Richmond Hill, Ontario, our dental team will assess your symptoms, determine the underlying cause, and recommend the most effective treatment to protect your oral health.

Why Professional Dental Care Matters
Although home remedies for mouth sores often provide relief in most cases, dental intervention may be necessary for an accurate diagnosis and treatment. A dentist can recommend topical medications, oral rinses, or other therapies to help with healing and address any underlying issues. Early diagnosis can also rule out more serious conditions, giving you peace of mind.
Tips to Prevent Mouth Sores
Prevention is just as important as treatment. Here are some strategies to help you reduce the risk of developing mouth sores:
- Practice good oral hygiene: Brush and floss your teeth daily, and visit your dentist regularly for cleanings and check-ups.
- Eat a balanced diet: Deficiencies in certain vitamins and minerals can contribute to mouth sores.
- Manage stress: Stress can trigger outbreaks in some people.
- Use a soft-bristled toothbrush: This reduces trauma to delicate mouth tissues.
- Avoid known triggers: If you notice certain foods or oral care products make you prone to sores, try to avoid them.
By following these guidelines and applying home remedies for mouth sores as needed, you can alleviate discomfort and promote oral health.
