The benefits of fluoride treatments and how they can prevent cavities

Unlock the secret to a healthier smile with the power of fluoride treatments. While most of us are familiar with fluoride as a key ingredient in toothpaste, its benefits go far beyond just cavity prevention. In fact, fluoride treatments have been proven to be a game-changer in dental care, offering a wealth of hidden benefits that are often overlooked.

From strengthening enamel to reducing tooth sensitivity, fluoride treatments provide a protective shield for your teeth, ensuring they stay strong and healthy for years to come.

In this article, we will delve into the science behind fluoride and its impact on dental health. We will explore the various ways fluoride treatments can benefit your oral hygiene routine and why they should be an essential part of your dental care regimen.

Understanding the importance of fluoride for dental health

Fluoride is a naturally occurring mineral that is found in water sources, soil, and some foods. When it comes to dental health, fluoride plays a crucial role in preventing tooth decay and strengthening tooth enamel.

It works by remineralising the enamel, which is the outer protective layer of the teeth. Enamel is constantly subjected to acids produced by bacteria in the mouth and the foods we consume. Over time, these acids can erode the enamel and lead to cavities. Fluoride helps to counteract this process by making the enamel more resistant to acid attacks, thus reducing the risk of cavities.

Research has shown that communities with fluoridated water have significantly lower rates of tooth decay compared to those without fluoride. This is why many municipalities add fluoride to their water supplies to improve oral health on a community-wide scale.

However, despite the widespread availability of fluoridated water, additional fluoride treatments can still provide significant benefits, especially for individuals at higher risk of tooth decay.

The history of fluoride in dentistry

The use of fluoride in dentistry dates back to the early 20th century when researchers began to notice that people living in areas with naturally high levels of fluoride in their water had fewer cavities. This observation led to the development of fluoride-based treatments and the introduction of fluoride in toothpaste. Over the years, extensive scientific research has been conducted to further understand the benefits and optimal use of fluoride in dental care.

Community water fluoridation has been carried out in countries around the world for more than 60 years including right here in New Zealand. Today, fluoride is widely recognised as one of the most effective tools in preventing tooth decay and promoting oral health.

A review carried out by the Prime Minister’s Chief Science Advisor and the Royal Society of New Zealand Te Apārangi in 2014 found that water fluoridation in New Zealand was perfectly safe,

“From a medical and public health perspective, water fluoridation at the levels used in New Zealand poses no significant health risks and is effective at reducing the prevalence and severity of tooth decay in communities where it is used. Communities currently without CWF [community water fluoridation] can be confident that this is a safe option that is cost saving and of significant public health benefit – particularly in those communities with high prevalence of dental caries.”

Here in New Zealand, tater treatment plants are monitored regularly to ensure fluoride concentrations do not exceed the maximum acceptable level set out in the Drinking Water Standards for New Zealand (ie, 1.5mg per litre). Any exceedances must be reported to Taumata Arowai (the water services regulator).

Community water fluoridation is affordable

The Sapere Research Group was commissioned by Manatū Hauora – the Ministry of Health in 2015 to examine the benefits and costs of water fluoridation.

The Sapere Report reviewed evidence found in numerous New Zealand and international studies and reports. It estimated the benefit of water fluoridation as follows: 

• 40% lower lifetime incidence of tooth decay among children and adolescents,
• 48% reduction in hospital admissions for the treatment of tooth decay among children aged 0-4 years,
• 21% reduction in tooth decay among adults aged 18–44 years,  
• 30% reduction in tooth decay among adults aged 45 years and over. 

Key conclusions of this independent report were that:

• “A large body of epidemiological evidence over 60 years, including thorough systematic reviews, confirms water fluoridation prevents and reduces dental decay across the lifespan.”
• “We estimate that adding fluoride to New Zealand’s water treatment plants classified as medium (i.e. those supplying populations over 5,000) is cost-saving, and for those plants classified as minor (i.e. those supplying populations over 500) it is likely to be cost-saving.”
• “Because of the increased amount of dental decay among Māori and those who are most deprived, we expect these groups to have a greater absolute benefit from water fluoridation.”

The Sapere report also estimated the average ongoing cost of community water fluoridation is just $2.60 per person per year for water supplies that serve populations of over 500 people and that every dollar spent on water fluoridation will save around $9 in dental care costs. These savings will mostly benefit individual New Zealanders needing to pay for fewer fillings and tooth extractions.

Benefits of fluoride treatments for preventing tooth decay

One of the primary benefits of fluoride treatments is their ability to prevent tooth decay. When applied to the teeth, fluoride interacts with the minerals in the enamel, forming a stronger compound that is more resistant to acid attacks. This process, known as remineralisation, helps to repair the early stages of tooth decay and prevent the development of cavities.

Fluoride treatments are particularly beneficial for individuals who are at higher risk of tooth decay, such as children, teenagers, and those with a history of cavities. Children, in particular, can benefit greatly from fluoride treatments as their teeth are still developing and more susceptible to decay. Regular fluoride applications can provide a protective shield for their teeth, ensuring that their smiles stay healthy and cavity-free.

In addition to preventing tooth decay, fluoride treatments can also help to reduce tooth sensitivity. Many people experience discomfort when consuming hot or cold foods and beverages due to exposed dentin, which is the layer beneath the enamel. Fluoride treatments can help to strengthen the enamel and reduce dentin sensitivity, allowing individuals to enjoy their favourite foods and drinks without any discomfort.

Furthermore, fluoride treatments have been shown to inhibit the growth of harmful bacteria in the mouth. By reducing the levels of oral bacteria, fluoride treatments can help to prevent gum disease and other oral infections. This is particularly important for individuals with compromised immune systems or those who are undergoing certain medical treatments that may increase the risk of oral infections.

How fluoride treatments work

Fluoride treatments are typically applied topically to the teeth in the form of a gel, varnish, foam, or rinse. The dentist or dental hygienist will carefully apply the fluoride treatment to the teeth and allow it to sit for a specified period. During this time, the fluoride ions penetrate the enamel, strengthening it and making it more resistant to acid attacks.

The fluoride treatment works by replenishing the lost minerals in the enamel and forming a protective layer over the teeth. This layer helps to prevent the demineralisation of the enamel and promotes the remineralisation process, resulting in stronger, more resilient teeth.

The frequency of fluoride treatments may vary depending on an individual’s oral health needs and risk factors for tooth decay. In general, children and individuals at higher risk of cavities may benefit from more frequent fluoride applications. It is best to consult with your dentist to determine the optimal frequency and timing of fluoride treatments for your specific situation.

Different types of fluoride treatments

Fluoride treatments are available in various forms, each with its own advantages and considerations. The most commonly used fluoride treatments include:

1. Fluoride Gel: Fluoride gel is a highly concentrated form of fluoride that is applied to the teeth using a tray or brush. It is typically left on the teeth for a few minutes before being rinsed off. Fluoride gel is often recommended for individuals at higher risk of tooth decay or those with existing cavities.
2. Fluoride Varnish: Fluoride varnish is a sticky, resin-based material that is painted onto the teeth. It adheres well to the enamel and slowly releases fluoride over time. Fluoride varnish is a popular choice for children and individuals with sensitive teeth as it provides long-lasting protection.
3. Fluoride Foam: Fluoride foam is a whipped foam that is applied to the teeth using a mouthguard or tray. It is left on the teeth for a few minutes before being rinsed off. Fluoride foam is easy to apply and can be a good option for individuals who have difficulty tolerating other forms of fluoride treatments.
4. Fluoride Rinse: Fluoride rinse is a liquid solution that is swished around the mouth for a specified time before being spat out. It is often recommended for children and teenagers who are old enough to rinse without swallowing. Fluoride rinse is convenient to use and can be incorporated into a daily oral hygiene routine.

It is important to note that fluoride treatments should always be performed by a dental professional to ensure safe and effective application. Your dentist will evaluate your oral health needs and recommend the most suitable type of fluoride treatment for you.

Who can benefit from fluoride treatments?

Fluoride treatments are beneficial for individuals of all ages, from young children to older adults. Children, in particular, can benefit greatly from fluoride applications as their teeth are still developing and more susceptible to decay. Regular fluoride treatments can provide an extra layer of protection for their growing teeth, reducing the risk of cavities and promoting healthy oral development.

Adults can also benefit from fluoride treatments, especially if they have a history of cavities or are at higher risk of tooth decay. As we age, our teeth can become more vulnerable to decay due to factors such as receding gums, dry mouth, or certain medications. Fluoride treatments can help to strengthen the enamel and protect against cavities, ensuring that our smiles stay healthy and vibrant.

Individuals with certain medical conditions or undergoing certain medical treatments that may increase the risk of oral infections can also benefit from fluoride treatments. By inhibiting the growth of harmful bacteria in the mouth, fluoride treatments can help to prevent gum disease and other oral infections, promoting overall oral health.

It is important to consult with your dentist to determine if fluoride treatments are suitable for you and how they can be incorporated into your oral care routine.

Potential risks and side effects of fluoride treatments

Fluoride treatments are generally safe and well-tolerated when performed by a dental professional. However, it is important to note that excessive fluoride intake can lead to a condition called dental fluorosis, which causes white spots or streaks to appear on the teeth. This condition is primarily a cosmetic concern and occurs when fluoride is ingested in excessive amounts during tooth development.

To minimise the risk of dental fluorosis, it is important to use fluoride products as directed by dental professionals and to supervise children to ensure they do not swallow fluoride toothpaste or mouthwash. Your dentist will evaluate your individual risk factors and recommend appropriate fluoride treatments to minimise the risk of dental fluorosis while maximizing the benefits of fluoride for your oral health.

If you have any concerns or questions about fluoride treatments, it is best to consult with your dentist, who can provide personalized advice and guidance based on your specific needs.

Incorporating fluoride treatments into your oral care routine

Fluoride treatments should be seen as a complementary component of a comprehensive oral care routine. While fluoride can provide significant benefits in preventing tooth decay and promoting oral health, it is important to combine it with other essential practices for optimal results.

Here are some tips for incorporating fluoride treatments into your oral care routine:

Brush with fluoride toothpaste

Use a fluoride toothpaste that is approved by dental professionals and brush your teeth thoroughly at least twice a day. This will ensure that your teeth receive a consistent dose of fluoride and are protected against cavity-causing bacteria.

Use fluoride mouthwash

Incorporate a fluoride mouthwash into your daily oral care routine. Swish the mouthwash around your mouth for the recommended time and then spit it out. This will provide an extra layer of protection and help to freshen your breath.

Floss daily

Flossing is an essential part of maintaining good oral hygiene. It helps to remove plaque and food particles from between the teeth and along the gumline, where toothbrush bristles cannot reach. By keeping your teeth and gums clean, you can reduce the risk of cavities and gum disease.

Maintain a balanced diet

A healthy diet plays a crucial role in oral health. Limit your intake of sugary and acidic foods and drinks, as they can contribute to tooth decay and enamel erosion. Instead, opt for a balanced diet rich in fruits, vegetables, whole grains, and lean proteins. Drinking plenty of water throughout the day can also help to rinse away food particles and maintain a healthy pH balance in the mouth.

Visit your dentist regularly

Regular dental check-ups are essential for maintaining good oral health. Your dentist can assess your oral health needs, provide professional cleanings, and recommend appropriate fluoride treatments based on your individual risk factors. These routine visits will help to identify any potential issues early on and prevent them from progressing into more serious problems.

By incorporating these practices into your daily oral care routine and following your dentist’s recommendations regarding fluoride treatments, you can ensure that your teeth stay strong, healthy, and cavity-free.
