What is Dental Caries?

Dental caries - tooth decay, the common cavity - is the most widespread chronic disease on earth. Nearly every adult and most children in India carry at least one. It is also almost entirely preventable, and curable without drama when caught early.

What it actually is

A cavity is not a worm and not bad luck. It is a chemical process: bacteria living in dental plaque digest sugars from food and release acid. That acid dissolves the mineral of the tooth - first the enamel surface, then the softer dentin beneath, and finally the living pulp at the centre. Left alone, the process ends in pain, infection and tooth loss.

Why it matters beyond the tooth

• Early decay is silent - no pain until it is deep, which is why waiting for pain is the losing strategy
• An abscessed tooth is a genuine infection - fever, facial swelling, occasionally serious spread
• Children's milk teeth matter: decay there damages the developing permanent tooth and the child's eating, sleep and schooling
• Mouth health tracks general health - severe gum and tooth disease travels with diabetes and heart risk

The hopeful math

• The first stage - a white chalky spot - is REVERSIBLE with fluoride and diet change
• Every stage after that is treatable: small filling, bigger filling, root canal, crown
• Prevention costs rupees; a root canal costs thousands - the economics of brushing twice a day are unbeatable

What this section covers

What causes decay, the symptoms stage by stage, the types dentists name, how it is diagnosed, home remedies that help and those that waste time, diet guidance, medicines and products, prevention that actually works, and the Ayurvedic view of dental care with its genuine traditional strengths and honest limits.

One-line summary

Dental caries is acid from sugar-fed bacteria slowly dissolving the tooth - silent early, painful late, reversible at the white-spot stage, always treatable, and far cheaper to prevent than to fix.
