Our teeth play a large part in shaping our mouths, helping us eat, talk, and smile. But how well do you know them? Do you know which one is a bicuspid and which is a molar? Understanding your teeth is the first step toward better oral health. When you know what each tooth does and how to care for it, you can prevent problems before they start.
At Valley Dental Health in Cockeysville, MD, Dr. Ashley Izadi and Dr. Roham Rafat help patients understand their teeth and how to keep them healthy for a lifetime. Whether you are due for a routine cleaning or need more advanced care, our team is here to guide you.
Primary vs. Secondary Teeth
Humans grow two complete sets of teeth in our lifetime: primary teeth and secondary teeth. Primary teeth are commonly known as baby teeth, and secondary teeth are the adult teeth.
Baby teeth begin growing when we are about six months old and are usually in place by age three. These 20 teeth are essential for chewing, speaking, and holding space in the jaw for the permanent teeth that will follow.
Secondary teeth begin replacing primary teeth between the ages of six and twelve years old. By the time we reach adulthood, most of us have 32 permanent teeth. However, not all of these teeth are the same. There are four types of teeth that serve different functions in the mouth, similar to the way players on a sports team all have different positions. They play their own role but work together as a team.
The Types of Teeth
Incisors
Incisors are the eight teeth in the front of your mouth that you see when you smile. There are four on top and four on the bottom. These teeth have a flat, sharp edge and are used to bite food into smaller, chewable pieces. They are also the most visible teeth when you smile, which is why they are the focus of cosmetic dentistry.
Canines
These teeth have a sharp, pointed appearance and are named after the fangs of a canine (dog). There is one canine on either side of each set of incisors, making a total of four canines in the mouth. Canine teeth are used for tearing and ripping food. They are also the longest teeth in the mouth and play an important role in guiding your bite.
Bicuspids (Premolars)
These teeth, also known as premolars, are used for chewing and grinding foods. We have four bicuspids, two on the top and two on the bottom, one on either side of the canine teeth. They are larger and stronger than incisors and canines, designed to withstand the pressure of grinding food into smaller pieces.
Molars
There are eight molars in the mouth, located in the back of the mouth. They are used for chewing and grinding food. There are four on top and four on the bottom. Molars commonly experience tooth decay because they are used more and are more difficult to clean thoroughly.
Wisdom Teeth
Some people grow third molars in early adulthood, which you might be familiar with as wisdom teeth. These have a higher probability of growing incorrectly and may need to be removed if they cause problems. Wisdom teeth can become impacted, meaning they don’t fully emerge from the gums, which can lead to pain, infection, and damage to adjacent teeth.
Understanding Tooth Anatomy
Each tooth has several layers that work together to keep it strong and healthy:
- Enamel: The outer layer of the tooth and the hardest substance in the human body. Enamel protects the inner layers of the tooth from decay and damage.
- Dentin: The layer beneath the enamel. Dentin is softer than enamel and contains microscopic tubules that lead to the nerve. When enamel wears down, dentin can become exposed, leading to sensitivity to hot, cold, or sweet foods.
- Pulp: The innermost layer of the tooth. The pulp contains nerves and blood vessels that keep the tooth alive. It’s located in the center of the tooth and extends down into the root.
- Root: The part of the tooth that is embedded in the jawbone. The root anchors the tooth in place and contains the pulp chamber.
- Crown: The visible part of the tooth above the gumline.
- Cementum: A layer of connective tissue that covers the root and helps anchor the tooth in the bone.
- Periodontal Ligament: Connective tissue fibers that attach the tooth to the bone and help absorb the forces of chewing.
Common Dental Problems and How to Prevent Them
Tooth Decay (Cavities)
Tooth decay occurs when bacteria in plaque produce acids that attack the enamel. Over time, these acids can create holes in the teeth called cavities. Cavities are more common in molars because they are harder to clean and have deep grooves where food can get trapped.
Prevention: Brush twice a day, floss daily, and visit your dentist regularly for cleanings and exams.
Gum Disease
Gum disease begins as gingivitis (gum inflammation) and can progress to periodontitis if left untreated. Symptoms include bleeding gums, bad breath, and receding gums. Advanced gum disease can lead to bone loss and tooth loss.
Prevention: Regular cleanings, daily flossing, and good oral hygiene habits can help prevent gum disease. Patients with gum disease may benefit from specialized periodontal therapy.
Tooth Sensitivity
Sensitivity to hot, cold, or sweet foods can be caused by exposed dentin, worn enamel, or gum recession.
Prevention: Use a soft-bristled toothbrush, avoid acidic foods and drinks, and talk to your Cockeysville dentist about treatment options.
Bruxism (Teeth Grinding)
Teeth grinding can lead to worn enamel, cracked teeth, and jaw pain. Many people grind their teeth at night without realizing it.
Treatment: A custom nightguard can protect your teeth and reduce the effects of grinding.
The Importance of Regular Dental Visits
Even with excellent home care, regular dental visits are essential for maintaining healthy teeth and gums. During a routine visit, your dentist will:
- Perform a thorough examination of your teeth, gums, and mouth.
- Take X-rays if needed to detect problems that aren’t visible to the naked eye.
- Clean your teeth to remove plaque and tartar buildup.
- Screen for signs of gum disease, tooth decay, and oral cancer.
- Discuss any concerns or treatment options.
Most patients should visit the dentist every six months. If you have gum disease or other ongoing issues, Dr. Izadi or Dr. Rafat may recommend more frequent visits.
