Dental Myths – Fact or Fiction

DENTAL MYTHS – FACT OR FICTION?

This month we’d like to look at some dental myths that are floating around and we get asked about regularly by our patients.

  • Rinse you mouth after brushing – FALSE
    • Rinsing with plain water or mouthwash washes out the active ingredients in toothpaste that protect teeth (such as Fluoride)
    • Spitting out after brushing leaves a thin layer of fluoridated toothpaste on the teeth, which gets absorbed into the enamel to slowly strengthen it
  • Charcoal is safe to whiten teeth – a bit of both
    • Charcoal can absorb and neutralise toxins, so it is often used in gastro cases.
    • It is claimed to similarly absorb tooth stains
    • Charcoal can be abrasive so can strip the enamel if overused
    • It can lodge at the edges of fillings or in cracks, leaving a stain behind
    •  
  • Oil pulling is good for teeth and gums – a bit of both
    • Swishing coconut oil around in the mouth for 10-20 minutes has been used in Ayurvedic medicine to reduce bacteria in the mouth
    • It is safe and may have similar effects to common mouthwashes
    • It doesn’t replace good brushing and flossing as will not remove all tooth deposits that may lead to cavities and gum disease.
    •  
  • Mouthwash is always good – False
    • Prolonged use of some mouthwashes can alter taste
    • Some studies have linked alcohol-containing mouthwashes to oral cancer
    • Good brushing and flossing, which removes plaque, is more beneficial that mouthwash
    • Some specific medicated mouthwashes prescribed by dentists may be essential for patients with gum disease or extensive cavities.
    • Many over-the-counter mouthwashes simply freshen the breath
  • Babies leach calcium from mum’s teeth – False
    • If mother’s calcium intake is low it will first of all be lost from her bones
    • Other things during pregnancy (e.g., snacking, reflux, vomiting) is more likely to increase tooth decay at this time
  • Root canals cause health problems – False
    • Root canals save teeth with infected nerves
    • There is no sound evidence to prove this link
    • This myth is from 1900s, when root canal treatment was primitive and not as precise as it is now.
