Posted on 8/15/2026 by Dr. Michael Allard |
 Taking care of your mouth is super important, not just for a bright smile, but for your overall health. That's where prevention dentistry comes in. One of the most important parts of good oral care is keeping an eye out for anything unusual in your mouth. Catching problems early, especially something like oral cancer, can make a HUGE difference. An oral cancer screening is a simple, painless way to check for early signs of trouble.
Why Oral Cancer Screening Matters
Oral cancer can affect any part of your mouth, including your lips, tongue, cheeks, gums, and the roof and floor of your mouth. Like any cancer, early detection is key to successful treatment. Many people don't realize they have oral cancer in its early stages because the symptoms can be subtle or mistaken for something else. That's why regular oral cancer screenings are so important. They can help find problems before they become serious.
Warning Signs: What To Look For
Knowing the signs of oral cancer can help you be proactive about your oral care. Here are some things to watch out for:
| • |
Sores That Don't Heal: Everyone gets a mouth sore now and then. But if you have a sore, ulcer, or irritation in your mouth that doesn't heal within two weeks, it's important to get it checked out. |
| • |
Red or White Patches: Look for unusual red or white patches inside your mouth. These patches, called leukoplakia (white) or erythroplakia (red), can be precancerous or cancerous. |
| • |
Lumps or Thickening: Feel around inside your mouth for any lumps, bumps, rough spots, or thickening of the skin. These could be signs of abnormal tissue growth. |
| • |
Difficulty Chewing or Swallowing: If you suddenly have trouble chewing, swallowing, speaking, or moving your jaw or tongue, it could be a sign of a problem. |
| • |
Numbness or Pain: Persistent numbness, pain, or tenderness in any area of your mouth or on your tongue should be evaluated. |
| • |
Changes in Your Bite: Notice if your teeth no longer fit together properly when you close your mouth. This could indicate a change in the structure of your jaw. |
| • |
Loose Teeth: Teeth that become loose for no obvious reason need to be examined. |
Who Should Get Screened?
While everyone should be aware of the signs of oral cancer, certain people are at higher risk and should be especially vigilant about screenings. These include:
| • |
Smokers: Tobacco use, including cigarettes, cigars, pipes, and chewing tobacco, is a major risk factor. |
| • |
Heavy Drinkers: Excessive alcohol consumption increases your risk. |
| • |
People with HPV: Infection with the human papillomavirus (HPV), especially HPV-16, is linked to certain types of oral cancer. |
| • |
Those with a Family History: If you have a family history of oral cancer, you may be at higher risk. |
Even if you don't fall into these categories, it's still a good idea to have regular oral cancer screenings as part of your routine oral care.
What To Expect During a Screening
An oral cancer screening is a quick and simple part of your dental check-up. Your dentist or oral surgeon will visually examine your mouth, looking for any abnormalities. They will also feel for any lumps or bumps in your neck and jaw. If anything suspicious is found, further tests, such as a biopsy, may be recommended to determine if cancer is present.
Taking good care of your mouth is about more than just brushing and flossing. It's about being aware of changes and taking action when something doesn't seem right. If you notice any of the warning signs of oral cancer, don't hesitate to schedule an oral cancer screening. Early detection can save lives.
