Can Bad Oral Hygiene Cause Cancer?

Feb 27, 2024

No, bad oral hygiene is not considered a direct cause of cancer. However, poor oral hygiene in Australia has been linked to an increased risk of mouth and throat cancers, according to the Oral Health Committee of the Royal Australasian College of Dental Surgeons.

This association is thought to be partially due to chronic inflammation caused by oral bacteria, potentially creating an environment conducive to cancer development. However, other factors like tobacco and alcohol use play a much stronger role in these cancers.

Maintaining good oral hygiene is still crucial for overall health, but it’s essential to remember it’s just one piece of the puzzle in cancer prevention. Want to get a check-up? Our friendly team is looking forward to welcoming you to our clinic.

What is Oral Cancer?

Oral cancer is a type of cancer that develops in the mouth and throat, affecting tissues like the tongue, lips, cheeks, gums, and the roof and floor of the mouth. While less common than other cancers, it can have a significant impact on individuals and their families.

How Does Oral Cancer Affect Your Mouth?

Oral cancer can cause various symptoms, including:

  • Mouth sores that don’t heal
  • Lumps in the mouth or neck
  • Difficulty swallowing or chewing
  • Changes in voice
  • Unexplained bleeding in the mouth
  • Loose teeth or dentures

Early detection and treatment are crucial for improving the chances of successful recovery. Regular dental checkups and self-examinations are essential for identifying potential signs early on.

What Causes Oral Cancer?

Several factors can increase the risk of developing oral cancer, including:

Risk Factor Explanation

Excessive alcohol consumption: Especially when combined with tobacco use Can damage oral tissue and weaken the immune system.
HPV infection (certain strains): Human papillomavirus Linked to some oral and throat cancers, with HPV 16 and 18 being the most high-risk strains.
Excessive sun exposure to lips: Particularly for fair-skinned individuals Increases the risk of lip cancer.
Poor oral hygiene: While not directly causative May contribute to chronic inflammation, potentially creating an environment for cancer development.


Can Poor Oral Hygiene Lead to Oral Cancer?

Studies have shown an association between poor oral hygiene and a higher risk of oral cancer. Chronic inflammation caused by gum disease and the presence of harmful bacteria in the mouth are potential contributing factors. However, poor oral hygiene is not the only cause of oral cancer, and other risk factors play a more significant role.

Dental Visits to Prevent Oral Cancer

Regular dental checkups are very important for early detection of oral cancer. Dentists can screen for abnormalities during routine examinations and recommend further investigations if necessary. Maintaining good oral hygiene practices, including regular brushing, flossing, and professional cleanings, can contribute to a healthy oral environment and potentially reduce the risk of associated complications.

  • Practising a healthy diet.

Oral cancer is a serious health concern, but it’s largely preventable through adopting healthy lifestyle practices, maintaining good oral hygiene, and attending regular dental checkups. By understanding the risk factors and taking proactive steps, individuals can significantly reduce their risk and improve their overall oral health.
