Cavities and fillings information
Cavities are hard tissue destruction caused by bacteria and acid erosion. Early stages may be asymptomatic, but progression can lead to sensitivity or pain. Standard treatment involves removing decay and restoring with filling materials. Deep decay involving the pulp may require root canal treatment. NHI covers basic fillings; specific materials or aesthetic needs are out-of-pocket. The following is neutral public information, not medical advice.
Frequently Asked Questions
Do cavities always need to be filled?
Cavities do not heal on their own. If left untreated, they may enlarge and affect the pulp. Whether treatment is needed and the method should be assessed 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, and amalgam, each with specific indications and properties. NHI covers basic fillings; specific aesthetic materials are out-of-pocket. Actual details should be confirmed with the clinic.
Does getting a filling hurt?
It depends on the depth of decay and individual condition. Local anesthesia may be used if necessary. Actual experience and procedures should be explained by the dentist.
What is the difference between a cavity and root canal treatment?
For shallow decay, removal and filling suffice. If decay reaches the pulp and causes 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?
The duration varies depending on the material, bite, and oral hygiene habits; the filling may wear or fall out and require replacement. Regular check-ups help detect issues early.
Does NHI cover dental fillings?
NHI covers basic cavity fillings; specific aesthetic materials, inlays, or self-paid treatments are not covered. Actual coverage and costs are subject to clinic policies and NHIA regulations.
