Can tooth decay be reversed?
Quick answer
Can tooth decay be reversed?
Partly, and only early. Tooth decay at the white-spot stage — before a physical hole has formed — can be stopped and partially remineralised with high-fluoride toothpaste, less frequent sugar and better cleaning.
Once a cavity has broken through the enamel the damage is permanent and needs a filling, from £175 at York House Dental Practice in West Byfleet. Caught early, it is the difference between simple monitoring and a filling.
Can early decay remineralise at home?
Enamel is in a constant tug-of-war: acids produced by plaque bacteria after sugar pull minerals out, and saliva plus fluoride put them back. Decay wins when the acid attacks are more frequent than repairs can cope with — five sugary hits in a day does far more damage than one larger one, because your teeth need 30–60 minutes to recover after each. That frequency, not volume, is the detail most people miss.
At what point does decay need a filling?
Dentists act on early decay without drilling: fluoride varnish, monitoring at your £52 examination, and treating white spots before they become holes — our white spots guide covers the cosmetic side. Once a cavity forms, a white filling from £175 stops the rot; deeper decay means root canal (£525–£775) or, worst case, extraction.
How do you prevent tooth decay?
The prevention stack is unglamorous but proven: fluoride toothpaste (1,350ppm or more) spit-not-rinsed, cleaning between teeth daily, sugar kept to mealtimes, and a check-up every six to twelve months. Children get fluoride varnish as routine. Membership from £22.99 a month bundles your examinations and hygiene visits so early decay never gets the years it needs.
