Cavity treatment and filling replacement
Restoring a tooth affected by decay and replacing a filling when clinically necessary. Treatment depends on the depth of the lesion and the condition of the remaining tooth.
About Service
Tooth decay develops when acids produced by bacteria in dental plaque damage the hard tissues of a tooth. Early changes can sometimes be managed without a filling, while an established cavity generally needs restoration.
The examination determines whether the problem is confined to hard tissue or involves the pulp inside the tooth. Inflamed or infected pulp may require more than a filling. An old filling is not replaced solely because of its age; the tooth and restoration need assessment first.
What the treatment or procedure involves
- Examination and assessment of the lesion.
- Selection of preventive care or restorative treatment.
- Treatment of an established cavity and restoration with the selected material.
- Advice on daily hygiene and control of decay risk factors.
Important considerations
- Deep lesions may require root canal treatment, so the scope of care cannot always be determined before assessment.
Indications
- A cavity that requires restoration.
- A filling defect requiring restoration after examination.
- Sensitivity, pain or a visible change is a reason for assessment, not proof of decay on its own.
Contraindications
- An early lesion without a cavity may be managed without drilling and filling.
- Inflamed or infected pulp needs a separate plan; replacing a filling alone may be insufficient.
- A tooth unsuitable for the proposed restoration requires discussion of alternatives.
Advantages
- Restoration of tooth shape and function where a cavity is present.
- An opportunity to retain the tooth when it can be restored.
