Adult teeth or permanent teeth replace the primary teeth. They aid in digestion, speech and general appearance. There are 32 permanent teeth, with the main difference from primary teeth is that there are 4 premolars and 6 molars in each arch.
At age six or seven, the first adult or permanent teeth come in. They are known as the "first molars," or the "six-year molars. They come in at the back of the mouth, behind the last baby or primary teeth.
The human teeth function to mechanically break down items of food by cutting and crushing them in preparation for swallowing and digesting. Humans have four types of teeth: incisors, canines, premolars, and molars, which each have a specific function. The incisors cut the food, the canines tear the food and the molars and premolars crush the food.
Healthy teeth are really important for our overall health. They help us to smile and speak and bite and chew the food we need to sustain ourselves. It's important to understand the different types of teeth you have throughout your life. Milk teeth are the first teeth we get as babies.
Teeth start developing in the unborn baby. Good nutrition from the mother during pregnancy is important in tooth development. The mother's diet should have adequate amounts of calcium, phosphorus, vitamin C, and vitamin D.
Since the enamel of permanent teeth is slightly transparent, the yellowish colour of the underlying dentine is shown through it. Therefore, permanent teeth will appear slightly yellowish. As we get older, the dentine increasingly grows thicker, and it is normal that our teeth become more yellowish.
Permanent teeth or adult teeth are the second set of teeth formed in diphyodont mammals. In humans and old world simians, there are thirty-two permanent teeth, consisting of six maxillary and six mandibular molarsfour maxillary and four mandibular premolarstwo maxillary and two mandibular caninesfour maxillary and four mandibular incisors. The first permanent tooth usually appears in the mouth at around six years of age, and the mouth will then be in a transition time with both primary or deciduous dentition teeth and permanent teeth during the mixed dentition period until the last primary tooth is lost or shed.
Sometimes, parents mistake 6-year molars for primary teeth because they arrive so early. However, they are permanent teeth, and need to be cared for as such. Baby teeth and adult teeth both require care and attention for a healthy smile.
