Children's 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.

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.

The Importance of Children's Dental Care

“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.

4 Steps for Your Child's Oral Hygiene and Fluoride Treatment

4 Steps to Your Child's Oral Hygiene and Fluoride

At Clínica Dr. Paulo Cardozo, guidance on oral hygiene and fluoride use follows a protocol adapted to the child's age and their individual risk of decay.

Oral hygiene assessment and caries risk

The dentist assesses the child's oral hygiene status, the presence of bacterial plaque, the condition of the gums and the individual risk of decay. When indicated, imaging examinations (bitewings) are requested to detect hidden cavities.

Personalised Guidance for Parents

Parents receive practical guidance on brushing technique, the appropriate amount of fluoride toothpaste for the child's age, brushing frequency, and the use of dental floss. The team tailors the recommendations to the family's routine.

Professional fluoride application (when indicated)

In children at high risk of tooth decay, the dentist may apply a high-concentration fluoride varnish to the tooth surfaces. The procedure is quick, painless and reinforces enamel protection for several months.

Follow-up at Routine Appointments

At the six-monthly appointments, the team checks the effectiveness of brushing, the condition of the teeth and gums, and adjusts the preventive plan according to the child's growth and needs. Guidance is reinforced at each appointment.

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.

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.
