Over the last century, dentistry has undergone a monumental transformation, with our understanding and capabilities evolving exponentially in recent decades. Unlike our ancestors, who lacked the technology and research we possess today, we now have a clearer picture of oral health. Let's delve into some historical dental misconceptions and the modern scientific truths that have replaced them.
Cavities: Not Caused by Tooth Worms
Centuries ago, particularly during the Middle Ages, a prevalent belief was that cavities were caused by tiny worms residing within teeth. It was thought that the wiggling of these "tooth worms" was the source of toothaches. This notion, however, is simply untrue. There are no worms that live in teeth. Modern dentistry has revealed that cavities are the result of plaque buildup on teeth. This plaque is teeming with enamel-eating bacteria that cause tooth decay.
While cavities remain a common issue, battling them no longer requires medieval weaponry. Instead, regular brushing, flossing (or interdental cleaning), and routine dental checkups are your best defenses. Consistent and proper oral hygiene is remarkably effective in preventing cavities from taking hold.
Everyone Has the Same Number of Teeth (Mostly)
Contrary to the belief of figures like Aristotle, who mistakenly thought men had more teeth than women, the reality is that men and women have the same number of teeth. This misconception highlights how even brilliant minds can be incorrect about certain biological facts.
Here's what you should know about the typical progression of teeth:
Most people have 20 baby teeth (primary teeth) that typically begin to emerge around six months of age, as noted by the American Dental Association.
As we age, these baby teeth are replaced by permanent teeth.
Adults generally have 32 permanent teeth, which include 8 incisors, 4 canines, 8 premolars, and 12 molars (this count includes 4 wisdom teeth).
The "mostly" in the title comes into play with wisdom teeth. It's common for wisdom teeth (third molars) to not erupt at all. Some individuals may have only one or two emerge, while others may have all four. When wisdom teeth do erupt, they often lead to issues like overcrowding or becoming impacted beneath the gumline, causing swelling and discomfort. This is why wisdom tooth removal surgery is a common procedure.
Teeth Develop Before Birth
Another widespread myth was that teeth only begin to grow after birth. This is also false. Both primary and permanent teeth actually start to develop while a baby is still in the womb. The only exception to this is wisdom teeth, which develop later during adolescence.
Just as we've learned that the world isn't flat and humans have indeed landed on the moon, we now know that tooth worms are a myth and teeth begin developing prenatally. Understanding these dental facts is beneficial, but even more important is practicing proper oral care to prevent cavities. Your dentist will certainly agree that good oral hygiene is a fact worth embracing.
