What are they a filling replaces Part of a tooth that has been lost because of decay or through accidental damage.
You may hear the dentist talk about ‘composite’, ‘glass ionomer’ and ‘compomer’ – these are different types of white, tooth coloured filling material.
What will my dentist do?
Your dentist will:
- Usually numb the tooth and adjacent area with an injection – some small filling may not need this
- Remove any decay, together with any old filling material, and shape the cavity using a small, high-speed drill
- Wash and dry the tooth blowing water and then air onto it Use one of a variety of means to isolate the tooth and keep it dry
- Apply a special adhesive to the tooth, typically in two or three stages, and then place the filling, again in stages
- Harden the filling material between stages of the filling procedure, by the use of a bright light stone inside the mouth- this is called ‘curing’
- Trim the filling as necessary and then polish it, checking that you bite together comfortably.
What are the benefits?
A tooth needs less drilling for a white, tooth coloured filling than for sliver filling.
Unlike sliver filling, white, tooth coloured filling materials, which come in different shades to match different coloured teeth, are glued into place, sealing the filling and helping to strengthen the remaining part of the tooth. White, tooth coloured filing of back teeth and making front teeth look better.
When used in back teeth, white tooth coloured fillings look better than sliver filings, but take longer to place, partly because they are finished and polished in one visit. White, tooth coloured fillings may not wear as well as sliver fillings but they do have the advantages that they can be repaired, rather than replace, as and when something goes wrong.
