A facing is a shell or layer of tooth-colored porcelain or composite that is placed by a Dentist over the facial surfaces of your teeth to correct uneven tooth alignment, worn tooth enamel, discoloration or spacing, and chips or cracks.
The differences between composite and porcelain
There are two types of facings: composite and porcelain. With both, the principle is the same. Shells are placed over the teeth. There’s a large difference between the type of materials that are used for facings
How long will a facing last?
A facing lasts for about 5 to 10 years and sometimes even longer. Smoking and drinking a lot of coffee or tea helps the discolouring of your teeth. A facing can wear out or get damaged if you for example grit your teeth or bite your nails. The dentist can always repair or replace a worn out or damaged facing. This treatment doesn’t damage the tooth itself.
The steps of a treatment for a composite facing
Choosing the colour
First the dentist chooses the right colour of your facing after discussing it with you. The dentist can show you the effect of the desired colour immediately. He has multiple colours to his disposal that he can mix to make your ideal colour. You can compare them by blending different types of paint.
2. Grinding the tooth
If it seems necessary, the dentist will grind a very
small layer off of your tooth. By doing that he creates space for the facing.
If he doesn’t do this, your tooth will become a little bit bigger.
3. Sticking on the facing
Before the dentist sticks the composite to your tooth, he will first treat your tooth with a type of acid. He will also apply an attachment layer on which he will then apply the still soft composite.
4. Forming the facing
After the dentists applied the composite to your tooth, he will globally change the material in the right form. He then uses a blue light to shine on the composite if the desired form has been reached. By doing so he hardens the composite. And lastly he grinds the composite in the desired form and polishes the surface. Then the facing is finished. If you aren’t okay with the form or colour of the facing, the dentist can correct it immediately after grinding off a little layer of composite.
