White Resin Fillings
A white resin filling (also known as a composite filling) is a tooth-coloured plastic and glass mixture used to restore broken/decayed teeth. White resin fillings can be used to improve the colour, size, or shape of a tooth, as well as close spaces between teeth, replace existing silver fillings (amalgam), and "invisibly" fix a broken or decayed tooth.
Whats Involved In Hacing A White Filling Placed?
Firstly, your dentist will conduct a dental examination to assess whether a white resin filling is suitable or if a larger restoration such as crown or implant is necessary. It can generally take longer to place a composite filling than it does for a metal filling. That’s because composite fillings require the tooth to be kept both clean and dry while the cavity is being filled. Composite resin will be built up in your tooth one layer at a time, with each layer hardened with a special blue light before the next layer is applied. When the process is finished, the dentist will shape the composite to fit the tooth. The dentist then polishes the composite to prevent staining, early wear, and potential discomfort from sharp edges. The larger the size being filled the longer it will take, but most procedures will be completed within one hour.
How Long Do White Fillings Last?
Your white filling should last for several years, and will discolour as any normal tooth would from drinking red wine, caffeine, tea or other foods and drinks which stain teeth. Regular check-ups can prolong the life of your white filling and keep it invisible and clean for a whiter and better smile.
Advantages Of Composite Fillings
- Composite fillings can be fitted into small holes so that means less drilling is required in preparation for the fillings.
- Composite fillings are cosmetically more attractive than amalgam fillings.
- Composite fillings can help insulate the tooth from extreme temperature changes
- Teeth that are filled with composite material tend to be stronger, it bonds to the surrounding tooth structure, while an amalgam filling may sometimes be weaker.
Disadvantages Of Composite Fillings
- Composite filling can take slightly longer to place than amalgam and the technique your dentist uses is more complex
- Some foods and drinks can stain composite fillings
Are Composite Fillings Suitable To Repair All Teeth?
Composite filling material is not as strong as natural tooth structure which is a good thing as it avoids creating wedging forces that lead to tooth cracking. However it also means that for teeth than are severely decayed or broken, resin fillings will not be as long lasting as a Crown or Onlay.
