That Sore in Your Mouth That Hasn't Healed in Two Weeks: What Should You Do?

If you have a lingering sore or lesion in your mouth that hasn't healed within two weeks, it's time to contact your dentist for an exam. This could be an early indicator of oral cancer, and the earlier we diagnose it, the better your chances are for successful treatment. Here's what you should know. 

The Facts about Oral Cancer

Oral cancer is a bit tricky to diagnose on your own because it often progresses slowly, doesn't cause too much pain in the beginning, and it can look much like other conditions, like a canker sore, which might cause you to dismiss it. However, a sore or lesion in your mouth that persists beyond two weeks is a red flag, and you should have your dentist take a look at it. 

Here are some of the other signs of oral cancer:

  • White or red patches on your soft tissues or gums
  • A hard spot or lump on your cheek, tongue or gums
  • Numbness on your tongue or lips
  • Pain or difficulties with chewing or swallowing
  • Earaches or pain

Oral cancer is one of the conditions that our dentists screen you for during every routine preventive exam, which is one reason why these visits are so essential for your oral health and overall well-being. When you consistently visit your dentist every six months for preventive visits, oral cancer is highly preventable. 

Protect Your Dental Health

Preventive cleans and exams also guard against concerns like tooth decay, gum disease, and cavities. You can also protect your dental health with a consistent home care routine that includes brushing your teeth twice daily and flossing once. This helps remove plaque and bacteria that contribute to problems like tooth decay and gum disease.
