Tooth Decay: Causes, Stages & Treatment
Tooth decay, also known as dental caries or cavities, is the destruction of tooth enamel caused by bacteria’s acids. Left untreated, decay can progress through the layers of the tooth, leading to pain, infection, and eventual tooth loss.
What Causes Tooth Decay?
Tooth decay is caused by a combination of factors, including:
- Accumulation of dental plaque
- Frequent consumption of sugary or acidic foods and beverages
- Inadequate brushing and flossing
- Dry mouth or reduced saliva flow
- Lack of regular dental visits
Common Signs and Symptoms
Early detection is key. Common symptoms include:
- White, brown, or black spots on teeth
- Tooth sensitivity to hot, cold, or sweet foods
- Visible holes or pits
- Persistent toothache
- Bad breath or a bad taste in the mouth
Stages of Tooth Decay
Understanding the progression helps determine appropriate treatment:
- Initial Demineralization – Enamel begins to weaken
- Enamel Decay – The surface breaks down
- Dentin Decay – Bacteria reach the softer dentin layer
- Pulp Damage – Infection reaches the tooth’s nerve
- Abscess Formation – Infection can spread beyond the tooth

Frequently Asked Questions (FAQs)
What are the first signs of tooth decay?
Early signs include white spots on the enamel, mild sensitivity, and occasional discomfort when eating sweet, hot, or cold foods.
Can tooth decay be stopped once it starts?
Yes. With professional intervention, the progression of tooth decay can be halted and the tooth restored using appropriate dental treatments.
How is tooth decay diagnosed?
Decay is detected through clinical examination, dental X-rays, and digital diagnostic tools to assess the extent and location of the damage.
Does every cavity need a filling?
Cavities that penetrate beyond the enamel typically require fillings or other restorations to prevent further damage and restore function.
How often should I have my teeth checked for decay?
Regular dental exams every six months are recommended, though your dentist may suggest more frequent visits based on your individual risk factors.
Can decay occur under a crown or filling?
Yes. Decay can develop at the margins of crowns or fillings if oral hygiene is inadequate or the restoration fails.
