Cavity and Filling Information
Cavities are hard tissue destruction of teeth caused by bacteria and acid erosion. Early stages may have no obvious symptoms, but progression can lead to sensitivity or pain. General treatment involves removing decay and restoring with filling materials; deeper decay involving pulp may require root canal treatment. Health insurance covers basic fillings, while specific materials or aesthetic needs are self-paid. The following is neutral public information, not medical advice.
Common progression of cavities
Cavities are progressive hard tissue destruction, with different treatment approaches at different stages:
- Early enamel demineralization: white spots appear on the surface, possibly asymptomatic.
- Decay reaching dentin: sensitivity to hot, cold, or sweet foods may occur; requires removal and filling.
- Deep decay involving pulp: bacteria invade the pulp causing inflammation or infection; may require root canal treatment.
General steps for fillings
A typical filling is completed in a single visit. Common steps are as follows, with local anesthesia if necessary:
- Remove decayed tooth tissue and prepare the cavity.
- Select filling material (e.g., composite resin) and fill in layers.
- Shape, cure, adjust occlusion, and polish.
Frequently Asked Questions
Do cavities always need to be filled?
Cavities do not heal on their own; if untreated, they may continue to enlarge and affect the pulp. Whether treatment is needed and the method should be evaluated by a dentist based on the extent of decay. This site only compiles public information.
What materials are used for fillings?
Common materials include composite resin (tooth-colored), glass ionomer, amalgam, etc., each with specific indications and characteristics. Health insurance covers basic fillings; specific aesthetic materials are self-paid. Actual details are subject to the clinic's explanation.
Does getting a filling hurt?
Depending on the depth of decay and individual condition, the dentist may administer local anesthesia if necessary. Actual sensation and management are subject to the dentist's explanation.
What is the difference between a cavity and root canal treatment?
For shallow decay, removal and filling suffice; if decay reaches the pulp causing infection, root canal treatment may be needed. This is determined by the dentist based on X-rays and examination.
How long does a filling last?
Longevity varies by material, occlusion, and oral hygiene habits. Fillings may wear or fall out and require replacement. Regular check-ups help detect issues early.
Does health insurance cover fillings?
Health insurance covers basic cavity fillings; specific aesthetic materials, inlays, or self-paid procedures are not covered. Actual coverage and fees are subject to the clinic and NHIA regulations.
