<strong>How to protect your child’s teeth from decay</strong>

Sharing is caring!

A child’s dental health is crucial, not just for their present well-being but also for their future. As UK dental professionals, it is part of our remit to advocate for preventive dental care, and one such method is through the application of dental varnish. This post will discuss how to protect your child’s teeth from decay and why dental varnish is so essential.

Understanding Tooth Decay in Children

Tooth decay, also known as dental caries, is a widespread problem among children. The combination of a sugar-heavy diet and inadequate dental hygiene practices often leads to the erosion of tooth enamel.

In the UK, it is a significant public health concern with almost a quarter of 5-year-olds having experienced tooth decay. This results in discomfort, an impact on a child’s quality of life, and sometimes the need for treatments using handpieces and other dental instruments.

The Role of Dental Varnish

Dental varnish, typically containing fluoride, is a proven method for preventing tooth decay. Fluoride is a natural mineral that helps rebuild tooth enamel and prevents the growth of harmful bacteria. The varnish is a concentrated form that is professionally applied to teeth surfaces and hard-to-reach areas.

It works in two ways: it strengthens the enamel and makes the tooth more resistant to acid attacks from bacteria, and it reduces the ability of bacteria to produce acid.

When to Start Using Dental Varnish

The sooner you begin the prevention, the better. As soon as a child’s first tooth appears, generally around six months old, dental varnish can be considered. The application of it is not limited to a specific age group.

It’s a preventive measure for children who are at a high risk of developing tooth decay, and it’s also suitable for older children and adults.

The Application

The process of applying dental varnish is simple, quick, and painless. Using a small brush, the dental professional coats the teeth surfaces with the varnish. This process usually takes a few minutes, and the child can eat or drink immediately after the application.

It is recommended that it is applied twice a year. However, for children at high risk of tooth decay, more frequent applications may be necessary.

Importance of Regular Dental Check-ups

Regular dental check-ups are crucial for maintaining your child’s dental health. A dental professional can examine your child’s mouth, identify potential issues early on, and take preventive measures such as advising on optimal oral hygiene practices.

During these visits, dental professionals can also show children how to brush their teeth effectively and can answer any questions that parents may have about their child’s oral health.

Other Preventive Measures

While dental varnish is highly effective, it should be viewed as part of a comprehensive approach to dental health. Other important aspects of oral care include:

  • Effective brushing: Ensure your child brushes their teeth at least twice a day using fluoride toothpaste. Teach them to brush all surfaces of their teeth.
  • Diet control: Limit the intake of sugary foods and drinks. Ensure your child has a balanced diet that includes plenty of vegetables and fruits.
  • Fissure sealants: These are a plastic coating applied to the chewing surfaces of the back teeth, protecting them from decay.

Building Trust and Comfort with Dental Visits

Taking your child to dental visits from a young age is not only about maintaining oral health but also about creating a comfortable and trusting relationship between the child and dental professionals. This familiarity reduces anxiety related to dental visits and treatments. Regular check-ups provide an opportunity for children to learn about their oral health in an engaging and informative way.

In these visits, dental professionals can use fun, child-friendly explanations to describe the importance of treatments like the application of dental varnish. Through this, they can impart the understanding that handpieces and dental instruments are friends, not foes.

The Role of Dental Professionals in Promoting Preventive Care

As dental professionals, we have an important role to play in promoting preventive dental care. We should consistently communicate with parents and caregivers about the importance of regular check-ups, maintaining a good oral hygiene routine, and a healthy diet. This includes providing age-appropriate resources and tips to parents and caregivers, facilitating better understanding and more effective implementation at home.

We can also lead by example, showcasing proper techniques for brushing, flossing, and even the application of dental varnish during visits. By doing so, we can help parents and caregivers ensure their children are on the right track towards maintaining their oral health. Ultimately, we should remember that we are part of a crucial team effort, along with parents, in protecting children’s teeth from decay.


A dental varnish is a powerful instrument in our preventive arsenal against tooth decay in children. Regular dental check-ups, combined with the use of dental varnish, an appropriate diet, and good oral hygiene practices, can help protect your child’s teeth from decay.

As dental professionals, it is our duty to educate and provide the highest level of care to our patients. By explaining the benefits and application of dental varnish, we are equipping parents with the knowledge they need to ensure their child’s long-term dental health. Remember, prevention is always better than cure, and it’s never too early to start.
