When you flash your biggest and brightest smile, your central incisor teeth are front and center. These are the two upper and lower teeth at the very front of your mouth. On either side of your central incisors are the lateral incisors, making eight incisors in total. Due to their position, incisors are the most noticeable teeth in your mouth, and they have various functions beyond playing the leading role in your smile. But what exactly is a central incisor, and why is it so important?

Central Incisor: Function and Shape
Central incisors are flat and thin, and they slice through food when you take a bite. Although upper and lower central incisors are similar shapes, they are different sizes. The upper central incisors are wide and the most prominent teeth in the human mouth. The lower central incisors are narrow and smaller.
Functions of central incisors include:
- Supporting the shape and appearance of the lips.
- Helping to pronounce certain sounds.
- Biting into the food you eat. Think of how you eat an apple or other solid food.
- Guiding the jaw into the correct position when the mouth closes.
When Do Central Incisors Appear?
Did you know that the central incisor is often a baby's first tooth? According to the Cleveland Clinic, the lower central incisors usually appear when the baby is six to ten months old. The upper central incisors follow, coming in between the ages of eight to 12 months. And just as they were the first to come in, the central incisors are often the first teeth children lose, usually at six or seven years of age.
Caring for Central Incisors
The central incisors' prominent position in the mouth means that any discoloration, decay, or chips are especially noticeable. They're the first thing that's noticed when you smile, so no wonder you want to take care of them!
If you're a parent, you should clean your babies' first teeth as soon as they appear. You can brush them twice a day with a toothbrush made of extra soft bristles. This ensures that you clean your baby's teeth effectively while also taking the gentle care necessary for your baby's developing mouth.
Teens and adults should also maintain a regular oral care routine and visit their dental professional every six months. A rigorous oral care routine includes brushing your teeth twice a day, cleaning between your teeth with floss, a water flosser, or an interdental brush, and rinsing with mouthwash to wash away any remaining bacteria. If the central incisors are poorly positioned, discolored, or chipped, orthodontists and dentists can use braces, teeth whitening, veneers, and a range of other treatments to fix the problem and improve your smile.
A central incisor was probably the first tooth to erupt in your mouth when you were a baby. Beyond the cuteness, central incisors perform essential roles in your everyday life. From eating and speaking to maintaining your facial appearance and jaw position, it's critical to keep your central incisors and your child's central incisors clean and strong. We recommend taking care of your central incisors as best you can. And don't forget to communicate with your dental professional if you notice any urgent issues!
