Improper toothpaste use can harm our health. Below are five common toothpaste misconceptions you should avoid. In fact, toothpaste isn't just for cleaning teeth—it has many practical uses in daily life that bring convenience.
1: Using too much toothpaste may increase oral cancer risk.
Several active ingredients in toothpaste raise concerns. The widely used chemical "sodium lauryl sulfate" is believed to potentially cause gastrointestinal issues and liver toxicity, making the mouth more susceptible to ulcers and oral cancer. Abrasives in toothpaste are also thought to damage gums, leaving them more vulnerable to injury. Therefore, avoid squeezing out too much toothpaste.
2: Improper use of fluoride toothpaste can cause dental fluorosis.The line between fluoride's anti-cavity benefits and its toxicity is very narrow. Excessive fluoride intake can cause spots on teeth, known as dental fluorosis, with children being the most common victims. This is because children often lack full control over swallowing, making them more likely to accidentally swallow fluoride toothpaste while brushing, leading to increased fluoride intake.Since toothpaste packaging typically lacks usage instructions, target audience information, or dosage guidelines, it often leads to adults and children sharing the same toothpaste. This practice is compounded by the tendency to apply excessive amounts of toothpaste to the brush, as demonstrated in television commercials.
Three: Children should avoid using high-foam toothpaste.
Children should avoid using high-foam toothpaste. Toothpaste falls into three categories: high-foam, medium-foam, and low-foam, with foam volume determined by soap content. High-foam toothpaste contains higher soap levels, which can irritate oral mucosa.
Experts advise consumers to use no more than 1 cm of fluoride toothpaste per application. Children should ideally avoid fluoride toothpaste or use it cautiously under parental supervision.Additionally, fluoride is a highly toxic substance. Excessive absorption can cause fluorosis. National regulations stipulate that free fluoride in fluoridated toothpaste should range between 400–1200 ppm. Particular caution is needed for children under 3–4 years old, as they may swallow 1/8–1/4 of the toothpaste.
Four: Using the same toothpaste morning and night is detrimental to oral health.
Dental experts recommend rotating toothpaste products according to seasonal changes and physical conditions, rather than consistently using the same brand or type. In advanced Western countries, over 80% of consumers use separate toothpaste for morning and nighttime brushing, and they also maintain regular dental check-up habits.Research indicates that most oral issues stem from bacteria. While human saliva naturally possesses antibacterial properties, daytime saliva production is 3-4 times higher than at night, effectively suppressing bacterial growth. During sleep, however, reduced salivary gland activity leads to oral dryness and acidification, failing to inhibit bacterial proliferation and triggering various oral problems.
5: Medicated toothpaste should not be used long-term.
Numerous medicated toothpastes—such as desensitizing, anti-inflammatory, deodorizing, and hemostatic varieties—have emerged, heavily promoted through widespread advertising. Many people treat these as miracle cures for oral diseases, using them regardless of whether they have dental issues. This practice is inadvisable.Oral bacteria fall into two categories: pathogenic and non-pathogenic. They maintain a delicate "ecological balance" within the mouth through mutual restraint.
Long-term use of medicated toothpaste with strong antibacterial properties not only causes pathogenic bacteria to develop resistance but also suppresses and kills normal oral flora while targeting pathogens. This disrupts the oral "ecological balance," potentially triggering new oral diseases and infections.Additionally, some medicated toothpastes contain alkaloids and highly irritating substances. Prolonged use not only damages the delicate mucous membranes in the mouth but also causes inflammation of the gums, oral cavity, and tongue due to constant irritation, leading to conditions like gingivitis, stomatitis, and glossitis.Individuals with allergic asthma may experience wheezing and gastrointestinal discomfort due to the pungent odor of medicated toothpaste. Some medicated toothpastes also contain dyes that, with prolonged use, can stain tooth surfaces, causing teeth to lose their luster and affecting their appearance.
For those with oral health issues, alternating between fluoride toothpaste and medicated toothpaste is advisable. For middle-aged and elderly patients with both cavities and periodontal disease, pairing fluoride products with herbal formulations morning and night is recommended. Those experiencing sensitivity to hot or cold should combine desensitizing anti-acid products with regular fluoride toothpaste.
