Care of the teeth
Although teeth are very strong, they need to be taken care of. There are many bacteria that live inside the human mouth. Some of these bacteria cause tooth decay. They also combine with saliva and food residues and form a sticky substance called plaque.
A build-up of plaque on the surface of the teeth can cause gum disease. Plaque is easily removed by brushing. If it is not removed, it hardens and forms a substance called tartar. This can only be removed by a doctor.
Bacteria in the mouth feed on food residues, mainly sugar, and produce an acid. This acid attacks the enamel, then the dentine. If it infects the pulp cavity, it causes pain which is commonly known as a toothache. If the infection spreads deep into the tooth, it becomes rotten and has to be extracted.
For your teeth to remain strong and healthy, take care of them as follows:
Floss your teeth once in a while. To floss is to clean between individual teeth using dental floss. Dental floss is a thread that is used to remove food and plaque between the teeth.
Rinse the mouth well after brushing.
Pay regular visits to the dentist, at least twice in a year, for dental check-ups.
To exercise your jaw and strengthen your teeth, eat hard food occasionally. You can, for example, chew raw carrots or sugarcane.
Eat a diet that contains enough supply of calcium, phosphorus, and fluorine, and vitamins A, D, and C. All these are essential for healthy teeth.
