DO YOU KNOW what the parts of the human tooth are? We’d like to give you a quick tooth anatomy lesson, because the more patients know about their teeth, the better they will understand the importance of good dental health habits like brushing, flossing, and avoiding sugary treats. We’ll start in the crown and work our way down to the roots.
The Three Layers of the Dental Crown
Everything visible of a tooth above the gums is the crown, and it consists of three layers. Let’s take a closer look at each one.
The outermost layer of the tooth is the enamel layer. Tooth enamel is mostly composed of inorganic hydroxyapatite crystals, which make it the hardest substance in the entire body. We need it to be that way so that we can chew a lifetime’s worth of food!
However, because it’s inorganic, enamel can’t repair or replace itself if it is eroded or damaged too much. It’s also extremely vulnerable to acid. That’s why brushing, flossing, cutting back on acidic and sugary foods and drinks, and regular professional cleanings are so important!
The next layer of the crown is the dentin, which is very similar to bone. It’s more yellowish than enamel and there’s more of it in adult teeth than baby teeth (if you’ve noticed that brand new adult teeth seem more yellow than baby teeth, that’s why). Microscopic tubules run through the dentin so that the nerves in the center of the tooth can detect temperature changes. When the enamel erodes, these become exposed and cause tooth sensitivity.
The Pulp Chamber
The core of the tooth is the pulp chamber, where the blood vessels and nerves are. The pulp is what makes a tooth alive and how we feel the temperature of our food. It’s also how we feel pain when something’s wrong with the tooth. Don’t ignore tooth pain; it’s the body’s natural warning sign that it’s time to see the dentist!
The Roots of the Teeth
Underneath the gumline are the roots of our teeth, which are longer than the crowns and anchored in the jawbone. They are cushioned and held in place by the periodontal membrane between them and the bone. Roots don’t have enamel to protect them; the gum tissue does that (as long as it’s healthy) and they are coated in a calcified layer called cementum. At the tip of each root is a tiny hole through which blood vessels and nerves can reach the pulp chamber.
Keep Those Teeth Healthy From the Roots to the Crowns!
Every part of the tooth, from the enamel to the pulp, from the crown to the supporting periodontal structures, needs to stay healthy. Keep brushing and flossing to protect the enamel and gums, and don’t forget your regular dental appointments!
JE, UNAJUA sehemu za jino la binadamu ni zipi? Tunapenda kukupa somo la haraka la anatomia ya meno, kwa sababu kadiri wagonjwa wanavyojua zaidi juu ya meno yao, ndivyo watakavyoelewa umuhimu wa mazoea mazuri ya afya ya meno kama kusafisha, kutumia kitambaa, na kuepuka vyakula vyenye sukari. Tutaanza katika taji na kufanya kazi njia yetu chini ya mizizi. Sehemu ya tatu ya taji la meno ni taji la meno, ambayo ni sehemu ya juu ya meno ambayo inaonekana. Hebu tuchunguze kila moja kwa makini zaidi. Safu ya nje zaidi ya jino ni safu ya enamel. Enamel ya meno ni ya inorganic hydroxyapatite, ambayo ni ngumu zaidi katika mwili. Tunahitaji kuwa hivyo ili tuweze kutafuna chakula kinachohitajiwa kwa maisha yetu yote! Hata hivyo, kwa sababu ni isiyo ya kikaboni, enamel haiwezi kurekebisha au kubadilisha yenyewe ikiwa imeharibika au kuharibiwa sana. Pia ni hatari sana kwa asidi. Hiyo ndiyo sababu ni muhimu sana kusafisha meno, kutumia kitambaa cha meno, kupunguza vyakula na vinywaji vyenye asidi na sukari, na kusafishwa kwa ukawaida na wataalamu! Safu inayofuata ya taji ni dentin, ambayo inafanana sana na mfupa. Ni manjano zaidi kuliko enamel na kuna zaidi yake katika meno ya watu wazima kuliko meno ya watoto (kama umegundua kwamba meno mapya ya watu wazima yanaonekana manjano zaidi kuliko meno ya watoto, hiyo ndiyo sababu). Vipande vidogo vya meno vinafanya kazi katika meno, na hivyo neva zilizo katikati ya meno huweza kutambua mabadiliko ya joto. Wakati enamel inapoharibika, hizo hufunuliwa na kusababisha udhaifu wa meno. Chumba cha Pulp - Chumba cha Pulp ni sehemu ya msingi ya meno ambayo ina mishipa ya damu na neva. Pulp ni sehemu ya meno ambayo hufanya mwili uwe na nguvu na ambayo hufanya mwili uwe na nguvu za kupima joto la chakula. Pia ndivyo tunavyohisi maumivu wakati kuna tatizo na jino. Usipuuze maumivu ya meno; ni ishara ya kiasili ya mwili ya onyo kwamba ni wakati wa kumwona daktari wa meno! Chini ya gumline ni mizizi ya meno yetu, ambayo ni ndefu kuliko taji na imewekwa katika mfupa wa taya. Vipuli hivyo huhifadhiwa na kushikiliwa mahali pake na utando wa meno ulio kati ya vipuli hivyo na mfupa. Mizizi haina enamel kuwalinda; tishu ya gum hufanya hivyo (kwa muda mrefu kama ni afya) na wao ni coated katika safu calcified aitwaye cementum. Kwenye ncha ya kila mizizi kuna shimo dogo ambalo mishipa ya damu na neva zinaweza kupitia. Weka Meno Yako Yakiwa Na Afya Kutoka Mizizi Hadi Vipande vya Meno! Kila sehemu ya jino, kuanzia enamel hadi pulp, kutoka taji hadi miundo ya periodontal inayounga mkono, inahitaji kubaki na afya. Endelea kupiga mswaki na kutumia kitambaa cha meno ili kulinda enamel na taya, na usisahau kwenda kwa ukawaida kwa daktari wa meno!
