Who Benefits from Fluoride Treatment?
While everyone can benefit, these groups see the most dramatic results from professional fluoride application.
Children & Teenagers
Developing teeth benefit most from fluoride. Applied every 6 months, studies show it may reduce childhood cavities by up to 43%
Dry Mouth Sufferers
Medications, medical conditions, or ageing can reduce saliva. Fluoride compensates for lost natural protection
Post-Whitening Care
Teeth whitening temporarily opens enamel pores. Fluoride reseals and strengthens for lasting results
High Cavity Risk
History of fillings? Sugary diet? Poor enamel? Fluoride provides excellent protection against future decay
The Science Behind Fluoride Treatment
Professional fluoride isn't just prevention — it's active repair for your tooth enamel.
Remineralise Weak Enamel
Fluoride penetrates the tooth surface, depositing calcium and phosphate to rebuild and strengthen weakened areas before cavities form
Reverse Early Decay
Catch and reverse white spot lesions and early demineralisation — avoiding the need for fillings entirely
Reduce Sensitivity
Clinical fluoride seals exposed dentine tubules, providing relief from hot, cold and sweet sensitivity within days
Protect After Whitening
Essential post-whitening care that remineralises enamel and reduces sensitivity after bleaching treatments
Safe for All Ages
Recommended for children (as soon as teeth erupt), adults with high cavity risk, and elderly patients with root exposure
Fast & Comfortable
Just 5 minutes in the chair. No tooth preparation, no discomfort, no downtime — eat and drink normally within 30 minutes
What to Expect
Your fluoride treatment takes just 5 minutes — here's how it works.
Clean & Dry
Teeth are polished and dried to ensure maximum fluoride absorption
Apply Varnish
Clinical-strength fluoride varnish is painted onto all tooth surfaces
Set & Protect
Varnish sets on contact with saliva, releasing fluoride over 24 hours
Ongoing Protection
Fluoride continues strengthening enamel for weeks after treatment
Fluoride Treatment FAQs
Everything you need to know about professional fluoride varnish
Professional fluoride varnish contains 22,600 ppm fluoride — approximately 100 times stronger than regular toothpaste (1,000-1,500 ppm). This clinical concentration penetrates deeper into enamel, providing protection that daily brushing simply cannot achieve. One professional application provides weeks of continuous fluoride release.
