About dental foundation treatment (core)
The tooth that has had its nerve removed by root canal treatment is hollow inside.A base is created to maintain strength (the cap is attached on top of the base).This foundation part is the "core."
Fiber Core
It is the newest and most tooth-friendly option. It is a material with moderate flexibility, which acts as a cushion and reduces the risk of tooth fracture. It is also white in color, so even highly transparent caps will have a natural color.
Benefit
- Moderate strength and cushioning, so it doesn't put strain on your teeth
- Because it is white, ceramic caps do not show through (natural tooth color).
- No risk of metal allergies
Demerit
- If the filling is not covered by insurance, it will be treated as an elective treatment and will incur costs.
- 1 tooth (in the case of private medical treatment)
- 12,000 yen (including tax)
メタルコア
This is a core made of metal. The advantage is that it is cheap because it is covered by insurance, but it has many disadvantages in terms of functionality.
Benefit
- Covered by insurance, so the cost is low
Demerit
- Too much strength and risk of fracture of the tooth root
- If you have a cap made of ceramic or other material, it will appear darker.
- There is a risk of metal allergies
Resin Core
This is a core made of resin (plastic material) and metal. A metal pillar is placed inside the white resin core to maintain its strength.
Benefit
- Since there are many white areas, it is difficult to darken the teeth even with a ceramic cap.
*Unlike fiber cores, there are some areas where the metal is visible.
Demerit
- Too much strength and risk of fracture of the tooth root
- As it is made of metal, there is a risk of metal allergies.
- If the filling is not covered by insurance, it will be treated as an elective treatment and will incur costs.
- 1 tooth (in the case of private medical treatment)
- 5,500 yen (including tax)
