If tooth decay is still in the initial stages, the dentist can still save the tooth through fluoride treatment, fillings, crowns and root canal treatment. But if tooth decay is already severe and an abscess has formed in the tooth, it may require tooth extraction.
Stages of tooth decay
- Tooth enamel begins to wear away because of acids produced by plaque bacteria
- Enamel gets weakened and breaks down further
- Tooth decay reaches the dentin (tissue beneath the enamel). Decay becomes much faster and you’ll experience tooth sensitivity (such as when you consume hot or cold drinks and food)
- Pulp damage occurs and this leads to swelling and pain
- Abscess forms and gums, jaw and face might swell. Severe pain is common.
