The Signs and Symptoms of Oral Cancer

Oral cancer is characterized by abnormal cell growth in the mouth, lips, tongue, or throat. With early detection, oral cancers have a high rate of successful treatment. The people at the greatest risk for oral cancers are those over the age of 45, but regardless of your age, you should opt for oral cancer screening if you’ve experienced any of the following symptoms:

  • Discoloured patches in your mouth or on your lips, including white or dark red in colour.
  • Unfamiliar lumps or unusual changes in texture.
  • Canker sores that won’t heal, numb patches, or persistent bleeding.
  • Unusual feeling tongue, change in sense of taste, and difficulty swallowing.

The Risk Factors for Oral Cancer

There are several behaviours and conditions that are associated with a higher risk of oral cancer. These include:

  • Smoking or consuming tobacco products such as cigarettes, cigars, and chewing tobacco.
  • Heavy or moderately heavy consumption of alcohol, especially combined with tobacco.
  • Possibility of human papillomavirus infection of the mouth.
  • Excessive exposure to the sun; a lifestyle that includes lots of sun exposure.
  • A poor diet or poor eating habits.
  • Family history of oral cancer.
  • Oral cancer is more common in men than in women.
  • A history of leukoplakia, which is a thick, whitish coloured patch that develops inside the mouth.

Prevention, Detection, and Treatment of Oral Cancer

Spotting Early Signs of Cancer

We want to keep our Dundas community healthy and thriving, so the goal of an oral cancer screening is the early detection of cancer or precancerous conditions in your mouth. During the exam, one of our dentists will look over the inside of your mouth and under your tongue for red or white patches or suspicious sores. We will also feel the tissues in your mouth to check for lumps or odd textures and may also feel the outside of your throat and neck for lumps.

Diagnosis and Treatment

If signs of cancer are detected during your oral screening, you may be asked to undergo additional testing, such as a biopsy (where a small piece of the suspicious tissue is removed for lab examination) or imaging tests like X-rays, ultrasounds, CT scans, or an MRI. To remove confirmed tumours, surgery, chemotherapy, or radiation therapy may be necessary.

Prevention of Oral Cancer

You can take steps now to help prevent oral cancer later. To help reduce your risk of oral cancer, see your dentist regularly for routine exams, stop using tobacco products, drink responsibly, be mindful of your exposure to direct sunlight, use UV protective lip balms, eat a healthy diet with plenty of fruits and vegetables, and during your routine brushing and flossing, check your mouth for signs or symptoms so that you can report any concerns to your dentist.

Contact us today

to schedule an initial consultation & exam.

Your consultation will include an examination of everything from your teeth, gums and soft tissues to the shape and condition of your bite. Generally, we want to see how your whole mouth looks and functions. Before we plan your treatment we want to know everything about the health and aesthetic of your smile, and most importantly, what you want to achieve so we can help you get there.

Frequently Asked Questions

If you have any of the risk factors for oral cancer, it’s a good idea to ask for an oral cancer screening during your regular dental exam. If you discover an unusually coloured or textured patch in your mouth or a lump or suspicious sore, you are encouraged to schedule an appointment to have it checked out.

Your dentist will examine your lips and the inside of your mouth, including your cheeks, gums, and all sides of your tongue. They will also carefully feel around for any lumps or unusual textures. The dentist may also feel your face, jaw, throat, and neck for unusual lumps or tenderness.

Wash your hands with warm soapy water. In front of your bathroom mirror, examine the roof of your mouth, your lips, tongue, and gums. Pull your top lip up and bottom lip down to see behind them. You may use a piece of gauze or a cotton pad to help you grip your tongue to check the sides and underside. Do your best to look at your gums and use your fingers to feel the insides of your mouth. You’re looking and feeling for colour changes, lumps, bumps, unusual textures, or tenderness. Let your dentist know if you have any sores that have not healed after two weeks.

Small, usually painless, flat patches that may appear red, white, gray, or yellow with red edges. These small patches can affect any area of the mouth, including the lips, gums, cheeks, tongue, and the roof of the mouth. As a good rule of thumb, it’s a good idea to have anything that looks or feels unusual checked out by your doctor or dentist.

It had been a while since my last dental visit — not because I didn’t want to go, but because my longtime dentist had retired (or changed career paths), and a new dentist had taken over the practice. As the “new kid on the block,” I was admittedly hesitant at first. I’ve always been a bit anxious about dental work due to very sensitive teeth (and what feels like an extra set of nerves in my jaw!), so it usually takes me time to build trust with a new dentist. That said, my experience at Dundas Valley Dentistry has been exceptional from day one. Dr. Osama has a truly outstanding chairside manner. At first glance, he may look young — but his knowledge, confidence, and calm, reassuring presence quickly put any concerns to rest. He takes the time to clearly explain what he’s doing before and during treatment, which made me feel completely at ease. Watching him work almost feels like watching an artist at their craft — precise, thoughtful, and professional. His dental assistant Bethany was equally professional and made me feel comfortable during this long procedure. Most recently, I needed caps placed on two cracked molars — a procedure that can be uncomfortable for someone with sensitive teeth like mine. Dr. Osama took extra care to ensure I was fully frozen and comfortable before proceeding. His patience and attention to detail made all the difference. When the caps were placed, they fit perfectly — no adjustments, no discomfort, just seamless work. The entire team at the front desk is equally fantastic — Hillary and Sarah are both friendly, welcoming, and thorough. They always take the time to explain upcoming procedures and what to expect at my next appointment, which I really appreciate. I’m very selective about who I recommend, especially when it comes to dentists — but Dundas Valley Dentistry is an easy 10/10. Absolutely deserving of a five-star review. ⭐⭐⭐⭐⭐

Honestly, the first week of January tends to be really stressful and moody and I couldn’t wait to get to this dentist to see Dr. Osama and his staff. That’s how much I really appreciate their vibe friendliness and support. Best dentist in Dundas.!

I enjoyed my experience both times I've been in this year. The staff in general are so lovely. The front desk staff are a true joy, and a pleasure to speak with. Dr. Osama is excellent and thorough. He explains very clearly where improvement is needed (flossing) but with understanding and kindness. I will now be flossing because I understand the function and importance. That's actually a big deal. Most grateful.

Can’t express how thankful I am with my cleaning experience. I haven’t felt this in quite a few years. Explaining every detail. The dentist was not pushy in getting things done but did let me know what was needed and I could do it when I wanted. The ladies at the front desk were so accommodating, helpful and worked with me on all the details. Thank you to everyone for such a wonderful experience! I will definitely be back and highly recommend anyone to try it.

Was looking for a new Dentist for my family, we gave Dundas Valley a shot and we love the fact we gave them a chance. They were great with my young kids which was my biggest concern. They taught them proper brushing techniques and really made them feel at ease. The Dentist is not always a fun trip but my son asked if we could go back the next day lol. If you're looking for a great dentist with an awesome team give Dundas Valley a shot.
