Canker sores are small but mighty when it comes to causing discomfort. These tiny sores can make eating, drinking, and even speaking a challenge. At Bowdental of Evanston, we understand how frustrating these oral irritations can be. Our dentist in Evanston is here to help you understand canker sores, their causes, and how to manage them effectively.
What Do Canker Sores Look Like?
Canker sores typically appear as small, round lesions with a reddish border. They form on the soft tissues of your mouth, including:
- The inside of your cheeks
- The sides and underside of your tongue
- The base of your gums
The center of the sore may be white or yellow, and while they are non-contagious, they can cause significant pain, especially when irritated by food, drinks, or speaking.
What Causes Canker Sores?
Several factors can trigger canker sores, including:
- Mouth Injuries: Accidental bites, sports injuries, or overly aggressive brushing.
- Dietary Sensitivities: Certain foods like nuts, chocolate, eggs, and spicy dishes can irritate sensitive mouths.
- Toothpaste Ingredients: Some people are sensitive to sodium lauryl sulfate, a common ingredient in toothpaste.
- Nutritional Deficiencies: Low levels of vitamin B-12, zinc, or other essential nutrients.
- Stress or Hormonal Changes: These can weaken your immune system, making you more prone to canker sores.
If you experience frequent or severe sores, it’s important to consult our dentist in Evanston to rule out underlying health issues.
How to Manage and Prevent Canker Sores
While canker sores can’t always be avoided, the following steps can help minimize their occurrence and discomfort:
- Maintain Good Oral Hygiene: Brush gently at least twice a day and floss daily to reduce bacteria buildup.
- Avoid Irritating Foods: Identify and limit foods that trigger sores for you personally.
- Use Protective Products: Look for a toothpaste and mouthwash designed for sensitive mouths.
- Keep Your Mouth Clean: Even with a sore, don’t skip brushing or flossing. This helps prevent infection and supports faster healing.
- Reduce Stress: Relaxation techniques may reduce stress-related outbreaks.
When to See a Dentist
Most canker sores heal within 7 to 10 days. However, if your sores last longer, are unusually large, or are accompanied by fever or extreme pain, it’s time to visit Bowdental of Evanston. Our dentist in Evanston can evaluate your oral health and recommend personalized solutions.
