\"Children<\/a>Those who have children will relate, and those who don’t will too: we have all experienced some kind of “battle” with our parents at tooth-brushing time. The good news is that children’s brushing can go from being a daily conflict to a moment of family connection<\/strong>, as long as it is approached with the right strategy. In this article you will find everything you need to know: when to start, how to adapt the technique to each age, and which tips really work to help little ones build the habit.<\/p>

The urgency is real. According to data published by Redacci\u00f3n M\u00e9dica<\/a>, 4 million children in Spain have tooth decay<\/strong>, which makes children’s oral hygiene a health priority, not just an aesthetic one. Starting on time and with the correct technique is the difference between a healthy mouth and years of avoidable treatments.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t

When to start children's brushing? An age-by-age guide<\/h2>\t\t\t\t<\/div>\n\t\t\t\t

One of the most common questions parents have is knowing when to begin oral hygiene<\/strong>. The answer is clear: sooner than you think. The Spanish Association of Paediatrics (AEP)<\/a> recommends starting from the first months of life, long before the first tooth appears.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t

From 0 to 2 years: cleaning gums and first teeth<\/h3>\t\t\t\t<\/div>\n\t\t\t\t
\n\t\t\t\t\t\t\t\t\t

Before any tooth erupts, clean the baby’s gums with a damp sterile gauze<\/strong> after feeds, especially the night feed. This gesture accustoms the baby to having their mouth handled and removes milk residues that can ferment.<\/p>

As soon as the first tooth appears \u2014 usually around 6 months, although it may be delayed until 14 \u2014 it is time to introduce a toothbrush with extra-soft bristles and a small head<\/strong>, specifically designed for babies. Fluoride toothpaste enters the picture from that moment: use an amount equivalent to a grain of rice of toothpaste with 1,000 ppm of fluoride<\/strong>. At this age the baby cannot spit, but that minimal amount is safe and effective for protecting the enamel.<\/p>

Brushing is always carried out by an adult: twice a day, with special attention to brushing before bedtime<\/strong>, since saliva production decreases at night and teeth are more exposed to bacteria.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t

From 2 to 6 years: supervised autonomy<\/h3>\t\t\t\t<\/div>\n\t\t\t\t

From the age of 2\u20133, children can begin to actively participate in their own brushing. Let them try on their own first \u2014 this builds autonomy and confidence \u2014 and then go over it yourself at the end to make sure no area has been left uncleaned. Adult supervision is essential until the age of 6\u20137<\/strong>, by which time most children have developed the fine motor skills needed to do it correctly.<\/p>

As for children’s toothpaste, from the age of 3 the amount increases to the equivalent of a pea<\/strong>, maintaining 1,000 ppm of fluoride. It is also at this stage that it is worth introducing dental floss<\/strong>: the AEP recommends starting to use it as soon as the teeth are in contact with each other, generally between the ages of 2 and 6, to remove the interdental plaque that the toothbrush cannot reach.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t

From 6 to 12 years: correct technique and mixed dentition<\/h3>\t\t\t\t<\/div>\n\t\t\t\t
\n\t\t\t\t\t\t\t\t\t

From the age of 6, children begin to lose their baby teeth and gain their permanent ones. This is the mixed dentition stage<\/strong>, in which temporary and permanent teeth coexist, and in which the first permanent molars make their appearance. These molars are particularly vulnerable to decay because they have deep fissures and children do not always reach them well with the toothbrush.<\/p>

From this age, toothpaste with 1,450 ppm of fluoride<\/strong> can be used \u2014 the same concentration as in adults \u2014 in a pea-sized amount. The child can now brush on their own, but it is worth checking from time to time that they are doing it correctly and not skipping the back molars.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t

Correct children's brushing technique step by step<\/h2>\t\t\t\t<\/div>\n\t\t\t\t
\n\t\t\t\t\t\t\t\t\t

Knowing how to motivate children is essential, but technique matters just as much, if not more<\/strong>: enthusiastic but poorly executed brushing does not remove the bacterial plaque where decay forms. Here is a simple and effective sequence:<\/p>

    \n
  1. Divide the mouth into four quadrants:<\/strong> upper right arch, upper left, lower right and lower left. Working by zones ensures no corner is forgotten.<\/li>\n
  2. Place the toothbrush at 45\u00b0 to the gum.<\/strong> This angle allows the bristles to reach the gingival margin, where the most plaque accumulates.<\/li>\n
  3. Make gentle circular movements<\/strong> over two teeth at a time, covering both the outer and inner surfaces. For preschool-age children, the circular movement technique (Fones technique) is the easiest to learn and execute.<\/li>\n
  4. Do not forget the chewing surfaces<\/strong> of molars and premolars: a gentle horizontal scrubbing over those surfaces removes residues accumulated in the fissures.<\/li>\n
  5. Brush the tongue<\/strong> with the toothbrush held perpendicular, making gentle sweeping movements from back to front. This reduces the bacterial load and improves breath.<\/li>\n
  6. Minimum duration: 2 minutes.<\/strong> Use a sand timer, a stopwatch or a two-minute song so the child knows when they have finished.<\/li>\n<\/ol>

    In children with mixed or permanent dentition, the modified Bass technique<\/strong> \u2014 bristles angled towards the gum with small vibratory movements \u2014 is the most effective for reducing plaque, including interdental plaque. Ask your paediatric dentist to show you both at the next check-up.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t

    Fluoride is the most important active ingredient in toothpaste because it remineralises enamel and slows the progression of decay<\/strong>. But the correct dose varies with age:<\/p>
