When it comes to toothpaste, we couldn't be more familiar with it. We brush our teeth with toothpaste daily, yet few realize that improper use can actually increase cancer risk. How is this possible? Though brushing is a daily routine, do we truly understand it? Are you aware of common brushing misconceptions? Let's explore these frequent pitfalls together—don't let ignorance harm your teeth any longer.
Using Too Much Toothpaste May Trigger Oral Cancer
It's widely known that an unclean mouth fosters bacteria and fungi, promoting the formation of nitrosamines and their precursors. When oral inflammation occurs, cells enter a proliferative state, becoming more sensitive to carcinogens and increasing the risk of oral cancer.
Chemicals like sodium lauryl sulfate, commonly found in toothpaste, are linked to stomach disorders and liver toxicity. They can increase susceptibility to oral ulcers, potentially leading to oral cancer.
Furthermore, abrasive agents in toothpaste may damage gums, making them more vulnerable to injury and compromising oral health. Therefore, avoid using excessive toothpaste to prevent oral cancer risks.
Beyond avoiding excessive toothpaste, other common brushing misconceptions also threaten oral health.
Four Major Misconceptions About Brushing Teeth
Misconception 1: Brushing Immediately After Waking Up
99% of people brush their teeth first thing in the morning before breakfast. This practice causes the effective tooth-protecting ingredients in toothpaste to be swallowed with breakfast rather than remaining on the teeth.
It's recommended to brush 20 minutes after eating. After waking up, rinse your mouth with water, have breakfast, and brush 20 minutes later for optimal health.
Misconception 2: Brushing with Cold Water
Many people habitually brush with cold water in the morning. This practice can actually cause significant harm to teeth.
Cold water can cause tooth sensitivity, especially for those with dentin hypersensitivity. Moreover, cold water hinders the active ingredients in toothpaste from working effectively. The main components of toothpaste are abrasives and fluoride. Laboratory studies have found that these active ingredients work best at around 37°C (98.6°F).It is recommended to brush with lukewarm water close to body temperature.
Misconception 3: Brushing horizontally
Many people habitually brush their teeth horizontally. This actually causes physical wear on the enamel. Horizontal brushing fails to remove debris from between teeth and may lead to issues like root wedge defects, gum damage, and dentin sensitivity.It is recommended to brush vertically along the gaps between teeth.
Misconception 4: Brushing Too Hard
Many believe vigorous brushing cleans teeth better, unaware that excessive force actually damages teeth. Applying about 200 grams of pressure—equivalent to lifting an ice pop with your fingers—is sufficient. Use wrist motion rather than arm force when brushing.
Preventive Measures for Oral Cancer
1. Avoid prolonged unnecessary sun exposure to prevent lip cancer.
2. Avoid smoking and alcohol consumption.
3. Denture wearers should promptly repair ill-fitting dentures. Seek immediate medical attention if pain or inflammation develops under the dentures.
4. Maintain a balanced diet with a mix of textures and proper nutrition. Avoid extremely hot liquids or foods to prevent irritating oral tissues.
5. Address oral diseases promptly. Remove broken roots or crowns (if present).
4. Maintain a balanced diet with a mix of coarse and fine foods for proper nutrition. Avoid consuming extremely hot liquids or foods to prevent irritating oral tissues.
5. Promptly address oral diseases: extract residual roots or crowns (non-restorable teeth), and wear well-fitted dentures to avoid tissue irritation.
6. Develop good oral hygiene habits and brush regularly.
