Frequently asked questions
How much does a fissure sealant cost in London?
Advertised prices for a fissure sealant in London currently sit at £25–£150 (44 clinics compared). The median is £52.50 - treat it as the going rate, not a quote.
Why do prices vary so much?
Four things move the price of a fissure sealant: the materials, who is doing it, how complex your case is, and the postcode. In London that currently spans £25 to £150 for the same headline treatment - which is why a “from” price is a starting point, never a promise.
Are these prices guaranteed?
No. Every figure is a real advertised fee recorded from the clinic, but fees move. The comparison tells you who to call first; the clinic confirms the final number.
Prices shown are indicative of advertised private fees and may change. They are a guide only - your individual treatment may differ. Always confirm the exact cost directly with the clinic before booking.
