Tooth decay

Good oral hygiene for children

Many parents ask themselves the question when and how to start promoting good oral hygiene habits for their kids.

Dentists emphasise that the sooner we start forming good dental hygiene habits for children, the greater are the chances for healthy and beautiful teeth in the future.

Good oral hygiene for children

The most important thing in oral hygiene for children is to take care of the child’s teeth from the first months of its life. If milk teeth are healthy, there is a bigger chance for strong permanent teeth. One should remember that teaching good oral hygiene habits to children should include cleaning teeth in the morning and in the evening, having appointments with the dentist and limiting snacks between meals.

0 – 2 years

We often forget that children are born with all tooth buds. At the beginning they are covered by the gums, but that doesn’t free us from the obligation to take care of the mouth from early childhood. At the beginning of creating good oral hygiene habits for children we should clean the oral cavity with a gauze swab or soft washcloth, at least two times a day. It helps to remove food remains and bacteria from the gums and mouth. During teething, which usually takes place between the 6th and 9th month of life, we should also clean the mouth with a gauze swab. After a few days from the tooth eruption, we should start brushing it with a baby toothbrush with soft bristles. At first, brush only with water, then consult your dentist or paediatrician to find out when is the appropriate time to start using kids toothpaste. Good oral hygiene is extremely important in the first months of the baby’s life, otherwise tooth decay may attack the newly erupted teeth. To avoid the so called “baby bottle tooth decay”, occurring in babies fed with milk, sugared mashes and juices, one should always take away the bottle after the baby has finished eating and should not put the baby to bed with it. To take care of the gums and teeth of a baby, one should use toothbrushes intended only for the youngest, which are made of soft bristles and fitted for the baby’s mouth.

When the baby turns one, we should take it for the first appointment with the dentist. During the appointment the parent can check if he/she takes good care of the baby’s teeth, and the baby has the opportunity to get to know the dentist's office, which will help to reduce the fear of the dentist in the future.

Over the age of 2

When the baby turns two, we should start using kids toothpaste (containing fluoride), which helps prevents tooth decay. We apply a small amount of paste onto the brush and we make sure that the baby spits out everything after brushing. Before the baby learns how to wash the mouth, after every brushing we should clean the teeth with a swab moistened with water. Between 3 and 4 years of age is the time when children start learning to brush their teeth on their own. It is important to choose the right toothbrush, which even in the hands of a clumsy 3-year old, will reach the places with difficult access.


Before the child turns 3, we should discourage it from sucking its thumb or pacifier, so that it won’t turn into a habit which may cause problems with the healthy development of the mouth and teeth. Habitual thumb or pacifier sucking in the period of teething, that is between the 6th and 12th month of life, may lead to various occlusion abnormalities, such as an open bite, which may cause discomfort during biting, and early wear of teeth. Between 3 and 5 years of age one should visit the dentist every six months because check-up appointments help the early detection of tooth decay or abnormalities in teeth, which then can be eliminated more easily.

Over the age of 6

After turning 6 years old, a crucial moment for children is when milk teeth start falling out and permanent teeth start to appear. It is advisable to prepare your child for the falling out of teeth, so that it won’t feel scared when it has to give away its first tooth to the “tooth fairy”.

Together with the eruption of permanent teeth, when mixed dentition occurs, the adjacent surfaces of milk molars are more prone to tooth decay. That’s why parents should start using dental floss to clean those areas.

A child isn’t able to take good care of its mouth, that’s why parents should supervise the cleaning and flossing of the child’s teeth until it turns 8 or 9. They can correct the child’s moves, if need be, so that it won’t form bad oral hygiene habits. One should pay attention to the cleaning of the side teeth, where more plaque builds up and which most frequently aren’t brushed by children because they have difficulty reaching them. It is extremely important because when the child is about 6 years old the first molar erupts! One should remember that after turning 6 children should use a toothpaste with up to 1500 ppm of fluoride.

Short tip

Do you know that children’s teeth begin forming before birth?

Over the age of 8

If we were scrupulous in teaching our children good oral hygiene, we can let them take care of their teeth on their own, when they turn 10. Now, our task is to choose the appropriate toothbrush and toothpaste, and remind them to brush their teeth in the morning, in the evening and when they eat sweets or drink sugared beverages. The best idea is to encourage children to eat sweet or salty snacks directly after the meal to limit eating between meals. As soon children turn 12 they should use dental floss on their own to clean adjacent surfaces of teeth. Encouraging children to take care of their mouth will help them to have beautiful and a healthy smile, which will have a positive impact on their lives because we all like smiling people better. What is more, good oral hygiene habits and good cleaning of teeth, will allow them to limit the appointments with the dentist in the future to painless check-up appointments.
