Myths and truths about dental health

Myths about dental health:

1. "Brushing harder cleans teeth better." (False)

   Recent studies have shown that brushing with too much pressure can cause enamel abrasion and gum recession, exposing the roots and increasing sensitivity. The ideal technique is gentle circular brushing to remove plaque without damaging the tissues.

2. "Cavities appear if you eat a lot of sweets." (False)

   While sugar remains a key factor in cavity formation, recent research highlights that the frequency of consumption is more important than the quantity. Processed foods, acidic drinks, and poor oral hygiene also increase risk. Modern cariology now emphasizes the balance between demineralization and remineralization, promoting the use of fluoride and xylitol to prevent cavities.

3. "If your gums bleed, it’s better not to brush them." (False)

   Bleeding is an early sign of gingival inflammation (gingivitis) caused by accumulated bacterial plaque. Stopping brushing only worsens the condition, allowing inflammation to progress to periodontitis. Current recommendations are to continue brushing and use dental floss.

4. "Chewing sugar-free gum replaces brushing." (False)

   The American Dental Association recognizes that sugar-free gums with xylitol can help reduce plaque and stimulate saliva production, but they DO NOT replace brushing. Plaque cannot be removed by saliva or gum alone; it´s necesary use the toothbrush and dental floss is necessary.

5. "If it doesn't hurt, there are no dental problems." (False)

   Current studies show that 60-70% of early-stage cavities are asymptomatic. Diseases such as initial caries, periodontal disease, and dental infections can progress silently. Semiannual checkups are essential to detect problems before they cause pain or require invasive treatments.

Oral Health Facts:

1. "Sugar promotes the development of cavities." (True)

Recent studies confirm that bacteria such as Streptococcus mutans and Lactobacillus metabolize sugars and produce acids that demineralize tooth enamel. The WHO recommends reducing free sugar intake to less than 10% of total daily calories to prevent cavities and other systemic diseases.

2. "Mouthwash does not replace brushing." (True)

Mouthwashes can help reduce bacterial load, but they do NOT remove the plaque adhered to teeth. Mechanical brushing and flossing remain the foundation of effective oral hygiene.

3. "Smoking harms oral health." (True)

Recent evidence shows that tobacco doubles the risk of periodontal disease and increases the risk of oral cancer up to 10 times. Additionally, vaping (e-cigarettes) also damages the oral mucosa and can cause gingival inflammation, so it is not a safe alternative.

4. "Dental hygiene in childhood is key to oral health in adulthood." (True)

Recent evidence shows that tobacco doubles the risk of periodontal disease and increases the risk of oral cancer up to 10 times . Furthermore, vaping (e-cigarettes) also damages the oral mucosa and can cause gum inflammation , so it is not a safe alternative.

5. "Dental hygiene in childhood is key to oral health in adulthood." (True)

Longitudinal studies show that children with poor habits have a higher risk of cavities and periodontal disease in adulthood. Current recommendations include:

✔ Using fluoride toothpaste from the eruption of the first tooth.

✔ Visiting a pediatric dentist.

✔ Avoiding bottles with sugary drinks.
