Why Do We Number Teeth?
The tooth chart that the dentists use to monitor changes in your dental health contains a diagram of your teeth. Each tooth is provided with a number that reflects the Universal Numbering System of the American Dental Association. The diagram is taken with your mouth wide open so that all the teeth are clearly visible.
- The numbering follows from the top right and continues going down to the bottom left. The first tooth on the right is number 1, and the last tooth on the left is number 16.
- The numbering of the bottom teeth then follows from left to right. The first tooth on the bottom left is number 17, and the last tooth on the bottom right is number 32.
- Numbers 1, 16, 17, and 32 are your third molars, also known as wisdom teeth. These may not be visible in your mouth if there isn’t enough space for them to come through.
What Is Inside a Tooth?
A tooth has several parts, and each part plays an important role in keeping your tooth healthy. Here is a simplified breakdown of each part:
- Crown: This is the outer part of the tooth that you can see inside your mouth. It’s covered with a hard outer layer called enamel. The crown helps you to chew food.
- Root: The root of the tooth is that part located under the gums and holds it in the mouth.
- Enamel: This is the hard, shiny outer layer of the crown. It protects the inside of the tooth from damage, such as cavities and decay.
“Do you know? Enamel is the hardest substance in your body, but it can still get worn down by things like sugary food or drinks.”
- Dentin: Just below the enamel, though softer than the enamel that supports the tooth.
- Pulp: This is the soft center of the tooth, and contains blood vessels and nerves. It helps the tooth to stay healthy and alive.
Tooth Chart For Different Ages
Children:
Children have 20 baby teeth, also known as primary teeth. These start coming in when babies are about 6 months old, and most kids have all their baby teeth by the time they are 3 years old.
As children age, their baby teeth gradually fall out and are replaced by 28 permanent teeth. Sometimes, the new permanent teeth push out the baby teeth, but mostly, new teeth come in the back of the mouth, behind the last baby tooth. Most kids lose all their baby teeth by the time they are 14.
| Age | Baby Teeth (Primary Teeth) | Permanent Teeth |
| Around 6 months | First baby teeth start to appear. | |
| Around 3 years | Most children have all 20 baby teeth. | |
| Around 6 years | First baby teeth start to fall out (lower central incisors). | First permanent teeth (6-year molars) come in. |
| Around 6-7 years | Adult central incisors appear (around the same time as 6-year molars). | |
| Around 12-14 years | Most children have lost all their baby teeth and have all 28 permanent teeth. |
Adults:
Most people develop four wisdom teeth between their late teens and early twenties, giving them a total of 32 teeth by the age of 21.
| Age | Teeth (Permanent Teeth) |
| Around 6 years | First permanent molars (6-year molars) come in. |
| Around 7-8 years | Central incisors (front teeth) come in. |
| Around 9-12 years | Lateral incisors (next to the central incisors) appear. |
| Around 10-12 years | Canines (cuspid teeth) come in. |
| Around 11-13 years | First premolars (bicuspids) come in. |
| Around 12-13 years | Second premolars appear. |
| Around 17-21 years | Third molars (wisdom teeth) come in if space allows. |
Tips For Keeping Your Teeth Healthy
- Brush Your Teeth Twice a Day – Brush your teeth for two minutes daily in the morning, and before bed preferably with fluoride toothpaste.
- Floss Every Day – Flossing helps clean between your teeth where a toothbrush can’t reach and cleans away food and plaque from your teeth.
- Eat Healthy Foods – Eat foods that are good for your teeth like fruits, vegetables, and dairy, and avoid too many sweet snacks and drinks.
- Drink a lot of Water
Drinking water helps wash out food particles and keeps your mouth moist.
