Oral Hygiene and Fluoride
Children's oral hygiene and fluoride use: how to protect your child's teeth from an early age
Supervised brushing and the correct use of fluoride form the foundation of cavity prevention in children.
According to the guidelines of the AAPD (American Academy of Pediatric Dentistry) and the EAPD (European Academy of Paediatric Dentistry), brushing with fluoride toothpaste should begin as soon as the first tooth erupts, using age-appropriate amounts and with parental supervision until at least the age of 7.
At Clínica Dr. Paulo Cardozo, in Benavente, the paediatric dentistry team guides parents on best oral hygiene practices for each age group and assesses the need for professional fluoride application based on each child's individual risk of tooth decay.
If you would like guidance on your child's oral hygiene and fluoride use, book an assessment appointment.
Digital imaging examinations
At Clínica Dr. Paulo Cardozo, the assessment of the child's oral hygiene is complemented by digital imaging examinations that allow detection of hidden cavities and monitoring of the health of the teeth and gums.
Caries Detection with Bitewing Radiographs
Bitewing radiographs are the reference examination for detecting caries between the teeth, particularly in areas that brushing cannot easily reach. They allow identification of lesions at an early stage, when intervention is simpler and more conservative.
Diagnosis with Periapical Radiograph
The digital periapical radiograph is used to assess a specific tooth in detail when deep caries or a root abnormality is suspected. It is a quick and comfortable examination for children, with a very low radiation dose.
Panoramic View with Orthopantomogram
The digital panoramic X-ray provides an overall view of the child's entire dental arch and allows assessment of the development of the permanent teeth, the presence of caries, and any anomalies. It is an important examination for long-term preventive monitoring.
“Teaching a child to care for their teeth from an early age is one of the most important investments parents can make in their child's health. With correct brushing, the right dose of fluoride, and regular check-ups, most cavities can be prevented.”
What is supervised children's oral hygiene and how is fluoride used in children?
Supervised children's oral hygiene consists of brushing the child's teeth under the guidance and active participation of the parents, until the child develops the manual dexterity needed to brush effectively on their own.
The EAPD (European Academy of Paediatric Dentistry) recommends that parents supervise brushing until at least the age of 7.
Brushing should be carried out twice a day with fluoride toothpaste.
According to the guidelines of the AAPD and the ADA (American Dental Association), the recommended amount of toothpaste is grain-of-rice sized for children up to age 3, and pea-sized for children between the ages of 3 and 6.
Fluoride is one of the most effective agents in the prevention of tooth decay. It acts in two ways: it strengthens tooth enamel and helps to remineralise areas where enamel is beginning to weaken.
In addition to fluoride toothpaste, the dentist may recommend the professional application of fluoride varnish to children at high risk of decay.
At Clínica Dr. Paulo Cardozo, guidance on oral hygiene and fluoride use forms part of every routine paediatric dentistry appointment, adapted to the age and individual risk of each child.

I didn't know the right amount of toothpaste to use for my 2-year-old son. The team's guidance was very clear and practical. We now brush together without any worries.

Everything you need to know about children's oral hygiene and fluoride
Tooth decay is the most common chronic disease in childhood, but it is largely preventable.
The foundation of prevention is daily brushing with fluoride toothpaste, a balanced diet, and regular dental check-ups.
Primary teeth should be brushed as soon as they erupt.
In the early years, parents are responsible for brushing, and as the child grows, responsibility is shared until the child can brush effectively on their own. Supervision is recommended until at least the age of 7.
The amount of fluoride toothpaste should be adjusted according to age: a grain-of-rice-sized amount up to age 3, and a pea-sized amount from ages 3 to 6.
It is important that young children spit out the toothpaste after brushing and do not swallow excessive amounts, to balance the protective effect of fluoride with the prevention of dental fluorosis.
Professional fluoride (fluoride varnish) can be applied by the dentist to children at high risk of decay, at intervals ranging from 3 to 6 months depending on individual risk.
This measure complements daily brushing and fissure sealants as part of a comprehensive prevention programme.
At Clínica Dr. Paulo Cardozo, prevention is the cornerstone of children's oral health. If you would like guidance on your child's oral hygiene, book an appointment.
Main Problems Prevented with Oral Hygiene and Fluoride
Supervised brushing and the correct use of fluoride allow the most common oral problems in childhood to be prevented.
At Clínica Dr. Paulo Cardozo, each child receives a preventive plan adapted to their age and risk. Find out about the most frequent problems.
Dental Caries in Childhood
Tooth decay is the progressive destruction of tooth enamel caused by acids produced by bacteria in dental plaque.
In children, the most commonly affected areas are the grooves of the molars and the spaces between the teeth. Brushing twice daily with fluoride toothpaste is the most effective measure to prevent it.
At Clínica Dr. Paulo Cardozo, caries risk assessment and personalised guidance on brushing and fluoride form part of every routine paediatric dentistry appointment.
Early Childhood Caries (Bottle Caries)
Early childhood caries affects very young children and is frequently associated with habits such as prolonged use of a bottle containing sugary liquids or falling asleep with a bottle.
Brushing teeth from the eruption of the first tooth and guidance on dietary habits are fundamental for its prevention.
At Clínica Dr. Paulo Cardozo, appointments from the first year of life allow risk factors to be identified early and parents to be guided on effective preventive practices.

Frequently Asked Questions

When should a child start brushing their teeth?
Brushing should begin as soon as the first tooth erupts, typically at around 6 months of age. In the early years, parents are responsible for brushing their child's teeth.
How much fluoride toothpaste should be used?
Up to age 3, the recommended amount is the size of a grain of rice. From ages 3 to 6, it should be the size of a pea. The toothpaste should contain fluoride at the concentration recommended by the dentist.
Until what age should parents supervise brushing?
Parental supervision is recommended until at least the age of 7. Before this age, most children do not have the manual dexterity needed to brush effectively on their own.
What is professional fluoride application?
This is the application of a high-concentration fluoride varnish to the tooth surfaces, carried out by the dentist. It is indicated in children with a high risk of tooth decay and reinforces enamel protection for several months.
Is fluoride application safe for children?
Yes. When used in the recommended quantities and frequencies, fluoride is safe and is one of the most effective agents in preventing tooth decay. The dentist adapts the dose and frequency to the individual caries risk of the child.
How many times a day should a child brush their teeth?
Brushing is recommended at least twice a day: in the morning and before bed. Brushing before bed is especially important because saliva production decreases during the night.
