How Human Teeth Have Evolved

You can tell a lot about a species from the shape of its teeth. For example, you can see that a dog or cat has two long pointed teeth in the front. These are called canines. In the wild, the shape of canines is optimal for tearing meat. Human teeth are designed to eat both meat and plants. Our canines are smaller than cats’ or dogs’, but they serve the same purpose. The flat teeth located in the back of our mouths, the molars, are optimal for chewing plants.

Throughout human history how we have used our teeth has changed. With the advances in technology, we have been able to place less and less strain on our teeth. Over time we developed methods of cooking that made food softer, built tools that break food into smaller pieces and created processed food so that is easier to eat. As a result, strong jaws and teeth became less and less essential for survival. While the need for strong teeth was diminishing over thousands of years, human teeth and jaws gradually became smaller. This is one of the reasons why there is often not enough room for wisdom teeth to grow in properly. Thankfully, the progress of modern technology has allowed us to safely treat this issue and maintain a higher level of oral hygene than our predecessors.

How is Toothpaste for Sensitive Teeth Different?

If you have sensitive teeth, you are not alone. According to The Journal of the American Dental Association, one in eight people have sensitive teeth. There are a variety of factors that could contribute to teeth sensitivity including eating acidic food, teeth grinding, brushing too aggressively, or anything else that erodes enamel. When enamel thins as the result of these activities, the nerves in the teeth are more vulnerable to painful stimulation such as hot or cold. Luckily, sensitive toothpastes are offered by many popular brands.

But what does sensitive toothpaste actually do for your teeth? Unfortunately, sensitive toothpaste can’t make enamel grow back. However, sensitive toothpaste can strengthen enamel, protecting it against more wear. Desensitising toothpaste can also reduce pain by preventing nerves from receiving painful stimulation and blocking the transmission of pain. Not all toothpastes offer the same qualities, so it is worth looking into which one is best for you.

Early Stages of Tooth Development

The story of your teeth starts at the eariest stages of life. Before a baby is even born, two sets of teeth have already begun forming under the gums. However, it is not until age 3-7 months that baby teeth first break through the gums. This is known as “teething.” It can take up to 3 years for all baby teeth to fully grow in. Babies and todlers need help learning to take care of their teeth.

Over the next few years, the jaw will grow and make room for adult teeth. At around age 6, baby teeth will begin to fall out. Occasionally, an adult tooth can partially grow in before the baby tooth has fallen out yet! This is perfectly normal. The last baby tooth has usually fallen out by around age 12.

Throughout your life, everyday use will wear down the outer layer of your teeth. This process can be slowed down by following advice from your hygenist and dentist. If taken care of properly, adult teeth can stay strong for your entire life!
