Study Notes
Tooth Development and Cavities
- Understanding tooth development is crucial for recognizing how and why cavities occur, and for preventing and treating dental issues effectively.
- Tooth development forms a foundation for maintaining dental health from an early age.
Cavities Formation
- Cavities are small holes or deteriorations that form on the surfaces of teeth due to bacteria that naturally reside in the mouth.
- These bacteria thrive on sugars found in foods and drinks, converting them into acids through a metabolic process.
- The acid produced subsequently attacks the enamel, the teeth's tough protective outer coating.
- Repeated exposure to these acids can erode the enamel, eventually leading to the formation of cavities.
Ancient Humans and Cavities
- Archaeological remains show that ancient humans had cavities in their teeth, likely caused by the same tiny microbes that live in our mouths.
- These microbes are present from birth and accumulate on our teeth as we eat, depending on our diet.
- Diets high in sugary foods cause an explosion of bacteria, leading to cavities.
- Ancient humans may have consumed low-sugar diets, but their teeth were still exposed to sugars from carbohydrates in root vegetables, nuts, and grains.
Treating Cavities
- Ancient humans used sharpened flint to remove rotten teeth and made rudimentary drills to smooth out holes left behind, as well as beeswax to plug cavities.
- Today, we have more sophisticated techniques and tools to treat cavities, including tooth fillings and fluoride in toothpaste and water supplies.
- The best way to avoid a cavity is by cutting down on sugar intake and practicing good oral hygiene.
Modern-Day Cavities
- The Industrial Revolution led to an increase in refined sugar consumption, resulting in a surge in cavities.
- Today, 92% of American adults have had cavities in their teeth.
- High sugar consumption is a major contributor to cavities, although some people may be more susceptible due to genetic weaknesses.
- Besides reducing sugar intake, using fluoride, practicing good oral hygiene, and avoiding sugary, starchy, and sticky foods can help minimize cavities.
