Teeth are essential by all means. They are instrumental, especially in grinding the food you take every day. You may not notice it, but your teeth are the best asset you have. Your smile won’t be complete without a good set of teeth. This is probably one reason why there are people who invest and spend money to beautify their teeth. Some individuals spend hundreds of dollars just to get the whitening treatment they want or to get the perfect smile they dream of. It’s really a good thing that people are still treating their teeth as gems that need to be taken care of properly.
Speaking of teeth, did you know that the anatomy of permanent teeth says that you can categorize your teeth into four? These four parts are, namely, molars, premolars, canine, and incisors. Molars are located in the inner part of the mouth, and these are usually used for grinding food. Premolars grow beside molars and canines. Canines are situated between premolars and incisors. And lastly, incisors are the teeth located in the front or close to the lips of humans. Knowing these categories can help you distinguish your own set of teeth or the teeth of your babies. Since premolars are one of the significant parts of your teeth, here are some of the useful data about this tooth type.
When do premolar teeth appear in babies?
The first premolar in the upper jaw comes out after 13 to 19 months while the second appears after 25 to 33 months. In the lower jaw, premolars appear after 14 to 18 months for the first premolar and 23 to 31 months for the second. The development of babies’ teeth can take up to 3 years before they can finally smile with a complete set of teeth.
At this stage, you may be challenged to distinguish premolars and molars. Well, they both have pits and fissures where the food can insert. Molars have deeper crevices, and it’s tougher to keep the cavities away from molars than premolars. Premolars in kids and adults have single roots except for the maxillary first premolars, which can have one or more roots.
When waiting for the teeth of your baby to come out, you must use a teether to aid in the development. Molars and premolars will appear late, so expect that your baby will have to spend a long time to feel the pain of teeth growing. And just in case you don’t know, premolar teeth are permanent teeth.
Where are premolars located?
Premolars are located between canines and molars. It usually grows in pairs. If you try to look at the anatomy of teeth, you will find two premolars beside the molars. Both the upper and lower jaws can grow this kind of teeth. The premolars of adults and kids are called maxillary first premolar, maxillary second premolar, mandibular first premolar, and mandibular second premolar. The maxillaries are located in the upper jaw while the mandibular first and second premolars are in the lower jaw.
How many premolars does a human have?
A human has eight premolars in total–4 in the upper jaw and 4 in the lower jaw. There are two maxillary first premolars in both sides of the mouth, two maxillary second premolars, two mandibular first premolars, and two mandibular second premolars.
What are the functions of premolars?
If molars are used entirely for griding food, what do premolars do? Since premolars are located between canines and molars, they serve as a bridge to get the food to the grinders. Premolars have two cusps, and they are considered as transitional teeth when a human is chewing or in the process of mastication. They possess the characteristics of canines so that food can be transferred to molars for grinding. Rather than from canine to molars, premolars stay in between to be the viaduct.
Whatever types of teeth you have in your mouth, it’s important to remember that you need to take care of them properly, especially the molars and premolars that can insert food and cavities easier. Brushing your teeth three or more times a day will lessen the possibility of decaying and breaking. but if that happens you could always use veneers to improve the aesthetics of your teeth. Your premolars need care too! Don’t hesitate to give them what they need.
