"Baby teeth aren't important."
Oh, no! Guys.
Oh, my goodness.
Can I rip this?
Yeah. Rip it, rip it.
Yah!
"Acidic fruits will whiten your smile."
Oh, please don't do this.
Lin: Yeah.
"Fillings last forever."
Yeah. They're kind of like relationships.
Hi, I'm Dr. John Yoo.
I'm a pediatric dentist in New York City and New Jersey.
It was between this and K-pop.
Lin: Oh, my God. [Yoo laughs]
Hi. I'm Dr. Jason Lin.
I'm an orthodontist, and I straighten teeth for a living.
And today we will be debunking myths about teeth.
"Cavities are irreversible."
That's all you, bud.
Yes, it's a myth.
That doesn't mean, though, that we've been fooling you guys
for your entire life.
Some cavities are reversible, some are irreversible.
Depends on the depth of the cavity.
If you look at the three layers of your teeth,
the outer layer, enamel,
has the capability to remineralize.
If the cavity is within the enamel,
technically it's reversible.
If the cavity penetrates to the second layer, dentin,
which is made up of a bajillion microtubules,
the bacteria can now shoot through the tubes
into the pulp, which is the center of your tooth
where your blood supply and your nerves are housed.
If it goes into the second layer,
I may recommend to the patient,
"Hey, this is most likely going to get bigger.
We don't know how fast, but we don't want to wait too long."
