An initial carious lesion is the earliest stage of dental caries (tooth decay). At this stage, the tooth surface is not yet cavitated (no hole).
Key points
What happens: Loss of minerals (demineralization) from enamel due to acids produced by bacteria.
Appearance: Often seen as a chalky white spot on enamel (called a white spot lesion), especially near the gum line or between teeth.
Pain: Usually no pain.
Reversibility: Yes — this stage can be reversed.
Management / Treatment
Improved oral hygiene
Topical fluoride (toothpaste, varnish, or gels)
Diet control (reduce sugary and acidic foods/drinks)
Saliva support (chewing sugar-free gum, staying hydrated)
Regular dental monitoring
Why it matters
If untreated, an initial carious lesion can progress to a cavity, which then requires a filling.
