What Is the Most Common Disease in the World Today?

More people get tooth decay, or cavities, than any other disease. Almost everyone in the world has a cavity sometime during his life.

How, then, do you get cavities? After you eat, tiny bits of food are left in your teeth. Bacteria that live on your teeth cause these bits of food to form an acid. This acid starts to eat away at the enamel, the outside covering of your teeth. This eating-away then goes deeper, to the dentin, the layer beneath the enamel and creates a hole, or a cavity.

If your tooth is not filled quickly, the cavity goes even deeper and reaches the soft pulp layer, which contains blood vessels and nerves. A cavity this deep can become infected. Not only is this a very painful toothache, but the infection can be carried to other parts of your body.

Therefore, to avoid this pain and infection, you should always brush your teeth very carefully several times a day to remove the food bits from your teeth.

Animals get cavities too, and they must be treated or the tooth pulled by a veterinarian!

  1. Moral lesson in this article would be to brush your teeth as often to prevent tooth decay, as it is the most common disease in the world.

  2. Tooth decay is the most common disease where food is left on teeth and carbohydrate like sugar is changed to acid demineralisation by plaque bacteria. Decay is easy to prevent.

    Over 80% of cavities occur inside pit and fissures on chewing surfaces where food is left trapped after every meal or snack and brushing cannot reach, while saliva has no access to neutralise acid and remineralise demineralised tooth like on other tooth surfaces.

    Fillings, sealants or chewing carbohydrate free food before eating to block meals or snacks being trapped and changed to acid, halt the caries process.

    Chewing fresh fibre veg like celery after eating forces saliva into trapped food to dilute carbohydrate like sugar, neutralise acid and remineralise demineralised tooth.

    The big challenge for toothbrush manufacturers is to produce a bush to chew toothpaste before brushing to force fluoride toothpaste inside pits and fissures to remineralise tooth like on other more accessible surfaces.

  3. Don’t forget about the bacteria responsible for dental daries: S.mutans! There are many cases where those with high caries rates also have a high occurance rate of these bacteria. Bacteria + carbs + tooth structure = decay
