Four facts about your smile

Four Facts About Your Smile

Learn some lesser-known facts about your teeth and gums.


The world of modern dentistry has seen many advances over the years. With it comes a wealth of information regarding our oral health. One of the best ways to stay on top of your oral health is to stay informed and educated about properly caring for your teeth and gums. Read on to learn some things you may not know about your smile…

1.  Enamel is the hardest substance in the body

The outermost layer of the teeth is known as enamel. The function of the enamel is to protect the teeth from damage, and for this reason, it is extremely tough. In fact, the enamel is the hardest substance in your body. Made up primarily of the minerals calcium and phosphate, the enamel is even stronger than the bones. It is because of the proteins and crystallites that it contains. Although enamel is very strong, it can still be damaged by bacterial plaque and acids. Therefore, you must take steps to protect it every day. Proper oral hygiene plays a key role in maintaining the condition of your enamel. It includes brushing your teeth with fluoride toothpaste and a soft-bristled toothbrush at least twice a day. It also involves eating a diet low in sugar and avoiding acidic foods and drinks.

2.  Your mouth is full of bacteria

Your mouth is naturally packed with many species of bacteria. Some of these, such as those found in plaque, can cause damage to the teeth. When these bacteria digest the sugars and other carbohydrates we eat, they convert these foods into acids that can erode the enamel of the teeth. If left to accumulate, bacterial plaque will continue to grow and spread. Eventually, it will harden into tartar and contribute to issues like tooth decay and gum disease.

You must remove bacteria and other debris from your mouth regularly. To do so, you should brush and floss regularly and see your dentist for a professional clean every six months.

3.  Saliva supports oral health

The body produces a considerable amount of saliva every day, and this helps maintain a healthy mouth. Saliva plays an important role in keeping your smile in good shape for many reasons. It washes away food debris after eating. It also contains minerals that help neutralise the effects of the acids found in plaque, reducing the risk of tooth decay and dental erosion. Saliva also makes it easier to swallow food and even plays a role in the digestive process.

If you suffer from dry mouth and suspect that you are not producing as much saliva as you should, it is a good idea to consult with your dentist.

4.  Your teeth are unique

Everybody has teeth that are unique to them, and no two people will have an identical smile. For this reason, dental records help identify human remains. Interestingly, the tongue also has a unique print, much like a fingerprint.

Everyone has 32 teeth — these include eight incisors at the front of the mouth, four canines, eight premolars, and 12 molars at the back of the mouth.
