Canker sores can be frustrating, especially when they make eating, drinking, and talking painful. While it might be tempting to skip brushing and flossing due to the discomfort, maintaining good oral hygiene is essential to the healing process. At Post Family Dental, we’ve compiled a guide to help you understand canker sores, what causes them, and how to manage them effectively.
What Do Canker Sores Look Like?
Canker sores are typically small, round, reddish sores that appear on the soft tissues inside your mouth. You might find them on your tongue, the sides of your mouth, or at the base of your gums. In some cases, the sore may have a yellow or white center, making it more noticeable.
What Causes Canker Sores?
Several factors can contribute to the development of canker sores, including:
- Injuries: Biting your lip or cheek, sports-related injuries, or even vigorous brushing can lead to these painful sores.
- Toothpaste Sensitivity: Some people are sensitive to toothpastes that contain sodium lauryl sulfate, which can trigger canker sores.
- Certain Foods: For some, foods like chocolate, eggs, nuts, and spicy foods can cause canker sores to appear.
- Nutrient Deficiencies: A lack of vitamin B-12 or zinc in your diet can also play a role in the formation of canker sores.
How Can You Manage Canker Sores?
The best way to manage canker sores is by maintaining good oral hygiene. Here’s how:
- Brush Gently: Continue brushing your teeth at least twice a day. Be gentle when brushing near the sore to avoid irritation, but ensure you’re cleaning the entire area to prevent plaque buildup.
- Floss Daily: Flossing helps remove plaque and food particles from between your teeth, keeping your mouth healthy and aiding the healing process.
- Use a Mouthwash for Mouth Sores: You may consider using a mouthwash specifically designed for mouth sores to help reduce pain and inflammation.
- Avoid Irritating Foods: While you have a canker sore, try to avoid foods that could further irritate the sore, such as acidic or spicy foods.
When Should You See a Dentist?
Most canker sores heal within a week or two. However, if you’re experiencing frequent outbreaks or if your sores don’t heal within a week, it’s a good idea to visit our dentist in North Loop Chicago. We can assess your oral health and provide guidance on how to manage recurring canker sores or offer treatments to speed up the healing process.
