Mouth Cancer

What is Mouth Cancer?

Mouth cancer is a dangerous abnormal growth that can affect any part of the mouth.


There are very few! and you won’t always be able to spot the earliest warning signs of oral cancer. That’s why regular check-ups with both your dentist and physician are so important. Your dentist is trained to detect early warning signs of oral cancer. If you are a smoker and drink alcohol, your risk of developing oral cancer is increased significantly.


In addition to check-ups, you should see your dentist if you notice any of the following:

  • A sore on the lips, gums, or inside of your mouth that doesn’t heal
  • A lump or thickening in the cheek that you can feel with your tongue
  • Loss of feeling or numbness in any part of your mouth
  • White or red patches on the gums, tongue or inside of mouth
  • Difficulty chewing or swallowing food
  • Soreness or unexplained pain in your mouth, or feeling that something is caught in your throat with no known cause
  • Swelling of the jaw causing dentures to fit poorly
  • Change in voice

Mouth Cancer Treatment 


You should expect your dentist to:

  • look at your face and neck
  • feet under your jaw and down your neck
  • examine the inside of your mouth with a small mirror, looking at your lips, cheeks, tongue, the roof of your mouth and your throat. Your dentist can see parts of your mouth that you can’t easily see or feel yourself. Your dentist may notice something in your mouth that needs to be monitored or needs to be seen by a specialist.
