What Is Fluoride Treatment?

Fluoride treatment is a professional dental procedure that strengthens tooth enamel and helps prevent cavities by applying a concentrated fluoride solution to the teeth. It is often recommended for individuals at increased risk of tooth decay, including children, adults with weakened enamel, and those with a history of frequent cavities.

At True Dental Studio, we provide fluoride treatment (starting at $27.25 NETT) as an optional step after teeth cleaning procedures such as scaling and polishing (starting at $49.05 NETT). This additional treatment helps protect the enamel and supports long-term oral health.

How Does Fluoride Treatment Work?

Fluoride treatment works by integrating into the tooth structure, remineralising the enamel, strengthening its surface, and enhancing its durability. This helps to:

  • Prevent Cavities – Strengthens enamel, making it more resistant to acid attacks from plaque bacteria, dietary acids, and acid reflux, reducing the risk of tooth decay.
  • Reverse Early Decay – Remineralises weakened enamel by restoring lost minerals, helping to halt the progression of early-stage cavities before permanent damage occurs.
  • Reduce Tooth Sensitivity – Helps protect exposed dentin by reinforcing enamel and blocking dentinal tubules (tiny channels in the dentin that transmit sensations to the tooth nerve), reducing discomfort from external stimuli such as cold, heat, and acids.

While fluoride is available in lower concentrations in home-use products such as toothpaste, mouth rinses, and prescription gels for daily maintenance, professional fluoride treatment in clinics provides a higher concentration for enhanced and prolonged protection.

Who Should Consider Fluoride Treatment?

Fluoride treatment offers advantages for people of all ages, particularly for those who are more prone to tooth decay. This includes:


What Happens During a Fluoride Treatment?

A fluoride treatment session is a quick and painless procedure that typically involves the following steps:

  1. Teeth Cleaning – Plaque and debris are removed, usually through scaling and polishing, to prepare the teeth for fluoride application.
  2. Application of Fluoride – A fluoride gel, foam, or varnish is applied to the teeth using a brush, tray, or swab.
  3. Setting Period – The fluoride remains on the teeth for a few minutes to take effect.
  4. Post-Treatment Care – Avoid eating, drinking, or rinsing for at least 30 minutes to ensure fluoride fully adheres to the enamel.

To maximise fluoride absorption, avoid hot, acidic, crunchy, or sugary foods and drinks, as well as brushing, for at least 4 to 6 hours. These can reduce fluoride’s effectiveness or wear away the varnish prematurely.

Are There Any Side Effects of Fluoride Treatment?

Fluoride treatment is generally well tolerated, but some individuals may experience mild side effects, such as:

  • Temporary Tooth Discolouration – Fluoride varnish may cause temporary white spots due to mineral deposition on the enamel, but these typically fade over time.
  • Mild Gum Irritation – Some individuals may experience slight gum sensitivity, especially if fluoride comes into contact with the soft tissues.
  • Nausea from Excessive Fluoride Ingestion – In rare cases, consuming too much fluoride can cause stomach discomfort, which is why professional application is carefully controlled.

How Often Should You Get Fluoride Treatment?

Fluoride treatment frequency depends on your oral health needs. Most people receive fluoride treatment every six months, typically during routine scaling and polishing, which helps keep teeth clean and maximises fluoride absorption.

For those at low risk of cavities, a yearly application may be sufficient. However, individuals with frequent cavities, weakened enamel, or a high risk of decay may require more frequent treatments as recommended by their dentist.

Frequently Asked Questions

Fluoride treatments are widely considered safe when professionally applied in appropriate amounts. They help strengthen enamel, prevent cavities, and reverse early decay. The controlled application minimises the risk of excessive fluoride ingestion, which can lead to mild side effects such as temporary tooth discolouration or nausea in rare cases. It is best to discuss with your dentist to determine if fluoride treatment is suitable and beneficial for your oral health needs.

Fluoride treatment is beneficial for both adults and children. For children, it strengthens developing enamel and helps prevent cavities. For adults, it remineralises weakened enamel, reduces sensitivity, and lowers the risk of decay, particularly for those with dry mouth, gum recession, or undergoing orthodontic treatment. The frequency and type of fluoride treatment may vary based on individual needs, so consulting a dentist can help determine the most appropriate approach.

Fluoride treatment is commonly referred to as 氟化处理 (fú huà chǔ lǐ) or 氟化涂层 (fú huà tú céng) in Chinese. Dentists may also describe it as 牙齿氟化 (yá chǐ fú huà), which translates to "tooth fluoridation." These terms are used to describe professional fluoride applications designed to strengthen enamel and reduce the risk of cavities.

Mild tooth sensitivity after fluoride treatment is not uncommon, especially for those with enamel wear or exposed dentin. As fluoride strengthens enamel and seals microscopic openings, temporary sensitivity to temperature changes may occur. This effect typically resolves within a few hours. If sensitivity persists, consult your dentist for further evaluation.

Fluoride treatment is generally recommended for individuals at higher risk of cavities, such as those with weakened enamel, frequent decay, orthodontic appliances, or dry mouth. While fluoride from toothpaste and water offers daily protection, professional treatment provides a higher concentration to strengthen enamel more effectively. Your dentist can assess whether fluoride treatment would be beneficial based on your oral health condition.

Fluoride treatments are generally well tolerated, but excessive ingestion may cause mild and temporary stomach discomfort. This is rare when applied by a dental professional, as fluoride exposure is carefully controlled to minimise intake. Avoiding food and drinks for at least 30 minutes after treatment can help reduce any discomfort.

You should avoid swallowing immediately after fluoride treatment to ensure it remains on your teeth for optimal absorption. While small amounts from saliva are generally harmless, excessive ingestion may cause mild stomach discomfort. It is recommended to refrain from eating, drinking, or rinsing for at least 30 minutes to maximise fluoride’s effectiveness.

Fluoride treatments are generally beneficial for preventing cavities, strengthening enamel, and reducing sensitivity. However, excessive fluoride intake may cause mild side effects such as temporary white spots on teeth or, in rare cases, stomach discomfort. When applied professionally in appropriate amounts, fluoride treatments support long-term oral health and cavity prevention.

It is recommended to wait at least 4 to 6 hours before brushing your teeth after fluoride treatment, especially if fluoride varnish was applied. This allows the fluoride to fully absorb into the enamel for maximum effectiveness. If a fluoride gel or foam was used, waiting 30 minutes before eating, drinking, or brushing is usually sufficient. Your dentist may provide specific instructions based on the type of fluoride treatment received.

Fluoride treatment strengthens tooth enamel, helps prevent cavities, and reverses early-stage decay by replenishing lost minerals. It also reduces tooth sensitivity by sealing dentinal tubules, which transmit sensations to the nerves. While daily fluoride use in toothpaste and mouthwash helps, professional fluoride treatment provides enhanced and longer-lasting protection.

After fluoride treatment, avoid hot, acidic, crunchy, or sugary foods for at least 4 to 6 hours, as they can reduce fluoride absorption and wear away the protective layer. Opt for soft foods and lukewarm beverages to maintain fluoride’s effectiveness. Refrain from alcohol or strong mouthwash, as they may interfere with the treatment. Following your dentist’s post-treatment care instructions helps maximise fluoride retention and enamel strengthening.

At True Dental Studio, fluoride treatment costs range from $27.25 to $65.40, available as an optional add-on after scaling and polishing. Our scaling and polishing prices range from $49.05 to $98.10 for children and teenagers (18 years and below) and $98.10 to $174.40 for adults. CHAS subsidies may apply for eligible individuals. Contact us for more details on pricing and financing options.

Fluoride treatment is beneficial for individuals at risk of cavities, enamel erosion, or tooth sensitivity. It provides additional protection beyond regular brushing and flossing, especially for those undergoing orthodontic treatment, dry mouth, or frequent acid exposure. While not essential for everyone, it is a cost-effective preventive measure that can reduce the risk of future dental issues and minimise the need for restorative treatments like fillings or crowns.

Fluoride treatment is generally well tolerated, but minor side effects can occur, such as temporary white spots on teeth, mild gum irritation, or stomach discomfort if excessive fluoride is ingested. In rare cases, overexposure to fluoride over long periods may contribute to enamel fluorosis, which causes discoloration. However, when professionally applied in appropriate amounts, fluoride treatment is widely regarded as safe and beneficial for dental health.

Fluoride treatments provide enamel protection for several months, typically lasting three to six months, depending on oral health and dietary habits. Regular fluoride exposure through toothpaste, mouth rinses, and dietary sources helps maintain protection between treatments. Fluoride treatment is generally recommended every six months, but individuals more prone to cavities or enamel erosion may require more frequent applications.

Yes, you can request to opt out of fluoride treatment at the dentist. While fluoride treatment is beneficial for most individuals, it is optional and based on your preference. If you have concerns about fluoride exposure, discussing them with your dentist can help determine whether fluoride treatment is suitable for your oral health.

Fluoride can help reverse early-stage cavities (demineralised enamel) by remineralising the affected area before it progresses into a cavity requiring a filling. However, fluoride cannot repair cavities that have already developed into deeper decay. If a cavity has formed, a dentist may need to restore it with a filling or other dental treatment.
