Dental
Services - Bonding
Bonding is a quick and painless way to repair chips in your
teeth. Bonding uses a white plastic paste, called composite
resin - a plastic that is semi-liquid at first, but that becomes
hard and durable when cured with light.
This material can be tinted to match the colour of natural
teeth and can also be contoured and shaped to resemble the
missing part of a chipped tooth. It can be painted over a
stained tooth, and it can make a fractured tooth look whole
and perfect. Composite resin can even build up the size of
teeth so gaps between them are reduced or eliminated.
| Here's How A Bonding Is Done: |
| Step 1 |
Your dentist paints a mild
gel on your tooth to make it a little rough. This step
helps the composite resin stick better to the enamel
of your tooth. |
| Step 2 |
The composite resin is mixed and tinted
to match the colour of your natural teeth. |
| Step 3 |
Your dentist puts the composite
resin on your tooth in layers. |
| Step 4 |
A very bright light is used
to harden (or cure) each layer of resin as it is put
on your tooth. |
| Step 5 |
After the last layer of composite
resin is hardened (or cured), your dentist shapes and
polishes the resin so the finished tooth looks natural
and smooth. |
Advantages:
 |
It's painless. There's usually only minor
drilling involved. |
|
It doesn't take much time. Several teeth
can usually be veneered in one visit. |
|
It costs a lot less than crowns. Before
direct veneering, crowns were the only way to improve
the look of chipped, widely-spaced or discoloured teeth. |
|
It can be used on children, because bonded
material can be removed and replaced as children's teeth
grow. |
Disadvantages:
|
Bonding treatment doesn't last as long
as crowns. It can last from five to 10 years, compared
to 10 to 20 years for crowns. |
|
Some composite resins can be stained by
tobacco, coffee, tea, blue berries, grape juice, cherries
and red wine. |
|
If the seal between your tooth and the
bonding material is not perfect, decay can occur under
the composite resin. |
