Early detection saves lives — here’s what to watch for.
Not every sore or spot in your mouth is cause for concern — but some dental symptoms may signal something more serious, like oral cancer. Recognizing the early signs is key to catching it early, when treatment is most effective.
Oral cancer can affect the lips, tongue, cheeks, gums, roof or floor of the mouth, and even the throat. While it’s more common in adults over 40, especially those who smoke or drink alcohol regularly, it can affect anyone — including people with no known risk factors.
Common Signs and Symptoms of Oral Cancer
Here are some warning signs that you should never ignore. If any of these symptoms last longer than two weeks, it’s time to book an appointment with your dentist or doctor.
- 🔴 Persistent Mouth Sores
A sore or ulcer that doesn’t heal, bleeds easily, or keeps coming back could be an early sign of oral cancer. - 🔴 Red or White Patches
Unusual red (erythroplakia), white (leukoplakia), or mixed red-and-white patches inside the mouth may indicate abnormal cell changes. - 🦷 Lumps, Bumps, or Thickened Areas
A new lump, swelling, or area that feels thicker than the surrounding tissue — whether on the tongue, cheeks, or floor of the mouth — should be checked. - 🔄 Numbness or Tingling
Unexplained numbness, tingling, or loss of sensation in your mouth, lips, or tongue may be a sign of nerve involvement. - 🗣️ Difficulty Swallowing or Speaking
Changes in how you speak, chew, or swallow — especially if they come on gradually — should be investigated. - 🔁 Changes in Bite or Jaw Movement
If it feels like your teeth no longer fit together properly, or you have trouble moving your jaw, it could be a sign of something deeper. - 🔥 Persistent Sore Throat or Hoarseness
Ongoing hoarseness, a sore throat, or the feeling of something being “stuck” in your throat can sometimes point to oropharyngeal cancer (affecting the throat or tonsils).
When to See a Dentist or Doctor
If you’ve noticed one or more of these symptoms for more than two weeks — especially if they don’t seem to be improving — it’s important to seek care right away. Don’t wait for pain: oral cancer can be painless in its early stages.
At our clinic, we include oral cancer screenings as part of your routine dental exam. These quick, non-invasive checks help us spot any abnormalities early and refer you for further testing if needed.
Who’s at Higher Risk?
While oral cancer can affect anyone, certain risk factors increase the likelihood:
- Tobacco use (smoking or chewing)
- Heavy alcohol consumption
- HPV infection (especially HPV-16)
- Excessive sun exposure (especially for lip cancer)
- Age (more common after 40)
- Poor oral hygiene or chronic irritation
- Family history of cancer
Even without these risks, regular checkups are your best defence.
Final Thoughts
Early signs of oral cancer often look and feel like common dental issues — but if they persist, they need attention. A simple dental visit could be life-saving.
