What This Blog Covers:

From early enamel wear to painful abscesses, we break down how cavities develop – and what treatment looks like at each stage. Learn when to brush more, when to fill, and when to call your dentist.

The 5 Stages of Tooth Decay

Early-stage tooth decay showing white demineralized patch on enamel

Stage 1: Enamel Demineralization

🧾 White or dull spots form as acid begins wearing away your enamel.
💡 Next Step: Remineralize with fluoride toothpaste and schedule a cleaning.

Stage 2: Surface Cavity

🧾 A hole forms in the enamel, but pain is unlikely. May go unnoticed without a dental exam.
💡 Next Step: Likely dental filling. Early detection prevents deeper damage.
Progressed cavity affecting tooth dentin layer

Stage 3: Dentin Damage

🧾 The decay reaches dentin – a softer layer below enamel – and spreads more rapidly.
💡 Next Step: A filling can still stop it here, but time is critical.
Tooth with decay reaching inner pulp causing pain

Stage 4: Pulp Exposure

🧾 The cavity hits the pulp (where nerves live). Pain becomes sharp and persistent.
💡 Next Step: Root canal therapy is needed to save the tooth.
Advanced tooth infection showing facial swelling and pain

Stage 5: Abscess & 
Bone Loss

🧾 Infection spreads below the tooth into the jawbone. May cause swelling or systemic issues.
💡 Next Step: Emergency care – often root canal or extraction required.

Why Cavities Happen

Tooth decay doesn’t appear out of nowhere – it’s caused by a mix of lifestyle and oral health habits:

Factor Examples
Diet Sugary snacks, soda, acidic drinks
Hygiene Skipping floss, brushing poorly
Risk Factors Dry mouth, genetics, lack of fluoride
Tooth decay linked to sugar and acidic drinks

What Happens If You Wait Too Long?

If a cavity progresses unchecked, the damage becomes permanent:

01
Nerve death
02
Jawbone loss
03

Infection entering bloodstream

04
