Parts of the Tooth and How to Protect Them
Your teeth are actually made up of different parts. Understanding how these layers work together helps you to take care of them and monitor your oral health. While each tooth is relatively small, the design of teeth is impressive.
Tooth Structure Basics
A human tooth has four main parts or layers:
- Enamel
- Dentin
- Pulp
- Cementum
In effect, these four sections of your tooth are like parts of a security system, with each protecting the one beneath it.
The part you visibly see is the crown, sitting above the gums and covered in enamel. Enamel is the hardest substance in the body. Although it’s tough, it’s not indestructible. Acid, abrasion from excess tooth grinding, and age can eventually break down tooth enamel, especially if it doesn’t receive the daily care it deserves.
Just under the enamel sits dentin. This layer is also hard, but not as hard as the dentin. This is partly because it contains many tiny channels that go between the exterior and the center of the tooth. When enamel wears down, dentin conveys drastic temperature changes (hot drinks or cold ice cream, for example) straight to the next layer of the tooth.
At the center of a tooth is the pulp, the living core of the tooth. Blood vessels nourish it, and nerves send signals when something’s off. It’s basically the tooth’s “alarm system,” and it doesn’t hesitate to speak up when needed. Just like a fire alarm or burglar alarm, you need to pay attention to signals that come from the nervous system inside each tooth.
Down where the crown meets the root is the neck of the tooth. Below that, the root anchors everything into the jaw, working cooperatively with the periodontal ligament, a fibrous support system that works like a suspension bridge. This structure provides shock absorption, while also promoting adhesion to the jawbone. That stability is beneficial every time you chew hard foods.
Cementum also coats the root and helps keep everything locked in place. Cementum quietly does its job, anchoring the root of your tooth, covering and protecting the dentin, providing additional shock absorption, and adapting and repairing the root surface when it becomes damaged.
Like reliable coworkers who never take a day off, all of these layers work together for your benefit. They do have a little help, though. The teeth rest in and are surrounded by a bed of tissue that is critical to their long-term health.
Gums Tissue Matters
The gingiva, or gums, wrap around each tooth like a protective collar, further anchoring them, sealing out harmful bacteria from reaching the dentin, and protecting the jawbone beneath. Healthy gums have the following characteristics:
- Firm and pink, not red or white
- Don’t bleed during brushing or flossing
- Fit closely around each tooth
If gums regularly bleed, look swollen, or feel tender, it’s usually the mouth’s way of alerting you to the need for professional attention! Be sure to address changes in your gums with your dental provider earlier rather than later for the best results. Waiting to long to address problems with the gums can quickly lead to an emergency dental visit.
Caring for the Teeth and Gums
Caring for your teeth and gums is the easiest way to avoid dental problems and preserve your them both for a lifetime. You can avoid dental emergencies by doing the following things regularly:
- Brush twice a day with fluoride toothpaste (yes, even when you’re “too tired”)
- Floss once a day
- Visit the dentist at least twice a year
- Go easy on sugary and acidic foods and drinks
- Relax the jaw and avoid clenching
Teeth respond well to a good hygiene routine, together with a good diet. Consistency is important. Your teeth will last longer as a result, and you can avoid the need for emergency dental services.
