What Makes Up Human Teeth?

What Makes Up Human Teeth?

Human teeth have several parts, each with its specific function. These parts work together to help us chew and grind food and speak clearly.

The first part of a tooth is the enamel, the hard, white outer layer covering the crown (visible part) of the tooth. Enamel is made up of tightly packed crystals of a substance called hydroxyapatite, which is a type of calcium phosphate. Enamel is the hardest substance in the human body and is responsible for protecting the tooth’s inner layers from wear and tear.

Beneath the enamel is the dentin, a softer, yellowish layer that makes up most of the tooth. Dentin is less hard and mineralized than enamel and composed of cells called odontoblasts. Dentin is important because it helps to support the enamel and provides protection for the innermost layer of the tooth, called the pulp.

The pulp is the soft tissue inside the tooth that contains nerves, blood vessels, and connective tissue. The pulp is responsible for providing nutrients to the tooth and maintaining health. If the pulp becomes infected or damaged, it can lead to tooth decay or a tooth abscess.

Teeth are anchored in the jawbone by the roots, which are not visible because the gums cover them. The roots of the teeth are made up of a rigid, fibrous material called cementum, which is responsible for attaching the tooth to the jawbone.

In addition to the enamel, dentin, pulp, and roots, teeth also have a layer called the cementum, which covers the tooth’s root and helps anchor the tooth in the jawbone.
There are four types of teeth in the human mouth: incisors, canines, premolars, and molars. Each type of tooth has a specific function and is designed for chewing or biting.

Incisors are the teeth at the front of the mouth and are used for biting and cutting food. Canines, also called cuspids, are sharp, pointed teeth located just behind the incisors and are used for tearing and ripping food. Premolars, also called bicuspids, are located behind the canines and are used for grinding and crushing food.

In addition to the different types of teeth, the human mouth also contains several other structures that are important for maintaining the health of the teeth and gums. These include the gums, the soft tissues that surround and support the teeth, and the tongue, which helps move food around in the mouth and aids in the process of chewing and swallowing.

Overall, human teeth are complex structures that play a vital role in food digestion and maintaining good oral health. By taking care of our teeth through regular brushing and dental check-ups, we can help to ensure that they stay healthy and strong throughout our lives.

  • My hygienist was Claudia, and I now have a best friend forever. She was so welcoming and kind, put me completely at ease, walked me through all of the procedures, costs, and reasons why, and introduced me to everyone who walked in or by the door. Dr. Smith was equally as helpful and amazing. Every person went out of their way to ensure my comfort and understanding. I NEVER write reviews, and was so impressed that I couldn't wait to get home and write one!

  • We love IHDC! They do everything possible to ensure our safety, and Alaine is an absolute gem! She treats my daughter with the patience of a saint and we love her for it! The whole team is amazing!

  • If you’re a believer in good vibes and positive energy then this is the place for you. Everyone here is so warm & inviting. They really do feel like family, ya know, the ones you actually like! I’ve been going here for years but when I had my daughter, there was no question about where i would take her for her dental needs. They are so great with her and she is never nervous when we go because they just radiate positivity and make her feel so calm and relaxed. I can’t recommend them enough. Oh, they are also really great with Botox 😉

  • Could not possibly thank Dr. Houck, Gabby, and staff enough for the wonderful care I receive. In addition to excellent dentistry, their compassionate approach and communication really sets them apart. They are always kind, caring, and take time to explain things in detail. Easy to contact the office with any needs, and they are always quick to respond. Highly recommend.

  • Just wanted to leave a quick review on Claudia! She is an excellent dental hygienist. She is very thorough with her cleanings, she has a sweet personality and takes the time to explain things to you. I 10/10 would recommend Claudia to all of my friends and family.

  • Amazing place. Started taking our family there in 2014. Professional, kind, and most importantly excellent at every level of service.
