If you’re curious about canker sores, our Phillips Ranch – Family & Cosmetic Dentistry team is happy to tell you all about them! Canker sores are red ulcers that have a white or yellow center. They generally develop on the inside of your lip or cheek or they form on the tongue. The causes and treatments of this sore include:


Even though the causes of canker sores are unknown, the sores tend to develop when you:

  • Are tired or stressed
  • Have hurt your mouth, such as biting your lip
  • Eat food that you are allergic to
  • Consume a product that contains a high amount of acid
  • Do not get enough vitamins and minerals in your diet
  • Are on your menstrual cycle, if you are a woman
  • Have braces


You don’t generally need a treatment for your canker sore because it should go away in a couple days. However, if you don’t want to wait for the sore to disappear, you can try using antimicrobial mouthwash, corticosteroid ointment, or an over-the-counter numbing solution. It is also recommended to avoid eating hot and spicy foods, foods with sharp edges (like nacho chips), and acidic products.
