Why does my child get cavities if he brushes his teeth?

We are all familiar with the importance of brushingto prevent tooth decay caries do not appear. The important thing is not only to brush, but also to do it properly.

It can be frustrating when even when brushing our teeth cavities continue to appearTherefore, we begin by clarifying that it is not only brushing alone that influences the development of caries.. Diet, saliva pH, enamel quality, and medication, among other factors, can also influence its occurrence.

As for brushing, we give you these 5 tips to carry them out with your children.

1. Let's start with the language

The tongue, in contrast to the teeth, has a rough surface where it large accumulation and growth of bacteria occursbeing one of the main causes of bad breath in children.

Whether with a toothbrush or a tongue cleaner, you can simply we must brush from as far back as we canand drag in the direction of on the tip of the tongue.

2. Time is important.

2. Time is important. Brushing should last for about 2 minutes and for this purpose it is advisable to have the help of an timerany type of clockor put some song for children to complete this time.

3. How many times a day?

Brushing is necessary 3 times a day, with the amount of fluoride indicated according to caries risk (1000 ppm fluoride, 1450 ppm fluoride or >1450ppm), which will be determined by your paediatric dentist. And with the amount of toothpaste according to age:

  • 6m-1 year: one scratch or half a grain of rice.
  • 2 years: one grain of rice.
  • > 3 years: one pea.

It is advisable to spit out the excess, but do not rinse after brushing.

4. Brushing mistakes

A error very common is to brush the teeth without touching the gums, So if we don't clean it properly, it will become inflamed and sometimes when we brush it, it will bleed and our child will be frightened.

It is important to teach them from an early age to brush "pink and white", i.e. the gum and the tooth. And if it bleeds, nothing happens, it is like a warning to tell us that we were not brushing that area properly and that it is inflamed because food has accumulated there. Until it is brushed gently, it will not reduce inflammation, nor will it stop bothering or bleeding, causing gingivitis.

5. Areas to brush

On the other hand, we must be aware of the areas to be groomed. Imagine the tooth in the mouth as a die, where we have both the outer part, the upper part (where we chew) and the inner part, which we have to brush with the toothbrush.

In addition, we have the lateral between tooth and tooth where food will be retained and the brush will not reach. To reach these spaces we need to use dental arches. The toothbrush should be passed through in a back-and-forth motion until it reaches the gum and then removed in the same way, removing any food debris.

Frequency and quality

It is important both the frequency as the quality from brushingIt is therefore necessary for parents to check how children do it, at least until how children do it, at least up to the age of the age of 8 years.

When in doubt, we can buy a plate developer which will stain the bacteria that accumulate on the teeth (dirt) and thus check in which area they are not brushing properly. This way we can make sure they are doing it properly.
