1. 0:00Wait, what is that black spot?
2. 0:03>> Drum, drum, feel the beat. Books are
3. 0:05smart, let's read and play.
4. 0:07>> Smart beats all day.
5. 0:11>> A cavity? What's that?
6. 0:12>> A cavity is a tiny hole in the tooth
7. 0:15caused by germs called bacteria.
8. 0:18>> Yuck.
9. 0:19>> So, the bacteria made that hole?
10. 0:21>> That's right. When we don't brush well,
11. 0:23they eat the enamel.
12. 0:24>> My strong enamel is getting weaker.
13. 0:27>> What is the enamel?
14. 0:30>> Before I tell you what is the enamel,
15. 0:33let's talk about the tooth parts.
16. 0:35>> Hmm.
17. 0:36>> Our tooth has [music] two main parts,
18. 0:39the crown and the root.
19. 0:43The crown has three special layers,
20. 0:46enamel, dentin, and pulp.
21. 0:49>> This is the enamel, the strongest part
22. 0:51[music] of the tooth. It's a super hard
23. 0:53shield. It's like armor.
24. 0:54>> Exactly.
25. 0:56>> But, cavities can break through it.
26. 0:59>> We're going inside the tooth?
27. 1:01>> Yes. Let's explore its layers.
28. 1:03>> Wow!
29. 1:04>> [screaming]
30. 1:05>> Look, this feels [music] softer. This
31. 1:08represents dentin. It supports the tooth
32. 1:10structure, but it's easier to damage.
33. 1:12>> They're going deeper.
34. 1:15>> Let's follow them.
35. 1:18>> Wow!
36. 1:22This is actually awesome.
37. 1:25>> This is the pulp, where the nerve lives.
38. 1:27>> Too hot. Too hot.
39. 1:30>> Yes, when the cavity reaches the nerve,
40. 1:32it hurts.
41. 1:32>> So, the nerve is inside the pulp?
42. 1:34>> Exactly. [music]
43. 1:35>> What do the nerves do?
44. 1:37>> I'm the tooth's messenger. When
45. 1:39something happens, I quickly send a
46. 1:41signal to the brain. If you bite
47. 1:42something hard, drink icy water right
48. 1:45away.
49. 1:46>> The nerve sends super fast messages to
50. 1:49the brainstem, telling your brain that
51. 1:51something is happening to the tooth.
52. 1:53>> So, that's why my tooth hurts when I eat
53. 1:56ice cream sometimes?
54. 1:57>> Exactly. I'm trying [music] to protect
55. 1:59your tooth by telling your brain that
56. 2:00something needs attention.
57. 2:02>> Healthy teeth keep the nerves safe
58. 2:03[music] and comfortable, but decay can
59. 2:05expose the nerves and make them very
60. 2:07sensitive.
61. 2:09Let's continue our adventure.
62. 2:11>> [laughter]
63. 2:20>> Woah! What is this pink soft texture?
64. 2:23>> These are the gums.
65. 2:25>> They hold teeth tightly. So, without
66. 2:27gums, teeth would fall out.
67. 2:29>> Exactly. They're super important.
68. 2:31>> And what is hiding under the gum?
69. 2:35>> The root.
70. 2:36It's the part of the tooth you can't
71. 2:38see.
72. 2:42>> What does the root do?
73. 2:44>> It holds the tooth tightly in the jaw
74. 2:46and helps keep it healthy.
75. 2:49>> Let's continue our adventure.
76. 2:53Look, we found the tonsils.
77. 2:55Hi tonsils. What do you do?
78. 2:58>> [laughter]
79. 3:00[music]
80. 3:02>> We're tiny guards.
81. 3:04>> We help catch germs and help keep your
82. 3:06body healthy.
83. 3:07>> Thank you, tonsils, for protecting us.
84. 3:11Let's go and tell Dad about what we
85. 3:12learned.
86. 3:13>> [laughter]
87. 3:15[crying]
88. 3:17>> Brush your teeth [music] every morning
89. 3:19and every night. Use floss to clean
90. 3:22between them. Clean your tongue to keep
91. 3:24it fresh. Visit your dentist, too. See
92. 3:26you next time.
93. 3:27>> It is fact time.
94. 3:31>> [music]
95. 3:33>> Wait, did you know that we have four
96. 3:35different types of teeth? [music]
97. 3:36Incisors are for cutting.
98. 3:38Canines are for tearing.
99. 3:41Premolars help crush food and molars do
100. 3:44the big chewing.
101. 3:46Here's another fun fact. Kids have 20
102. 3:49baby teeth.
103. 3:50>> When we grow up, we usually have 32
104. 3:52adult teeth. See you next time.
