Bonding
Imagine a quick, painless way to fill in small chips, disguise
cracks, bridge a gap, or cover discoloured teeth. Bonding can do
all this and more. Bonding is made possible by composite resin,
a plastic that is semi-liquid at first, but that becomes hard and
durable when cured with heat or light. This material can be tinted
to match the colour of natural teeth. Composite resin can be contoured
and shaped to resemble the missing part of a chipped tooth. It can
cover over a stained tooth. 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.
Advantages:
- It can be painless. There may be very little if any drilling
involved.
- It takes relatively little time to do. Unlike crowns, bridges
or veneers, one appointment may be all that is needed.
- It costs a lot less than crowns. Before bonding, 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.
Drawbacks:
- Bonding treatment doesn't last as long as crowns. On average,
it usually lasts about 5-10 years, compared to 10-20 years for
crowns.
- Some composite resins can be stained by tobacco, coffee, tea,
blueberries, grape juice, cherries, and red wine.
- If the seal between your tooth and the bonding material isn't
perfect, decay can occur under the composite resin.
Veneers
Veneering involves covering the fronts of teeth with a thin layer
of extremely thin acrylic or porcelain shells. When teeth are severely
stained, badly chipped, or very uneven, it may be recommended that
an acrylic or porcelain veneer be used instead of bonding. Veneers
are extremely thin, very strong shells that are attached to the
front surfaces of teeth. They are usually applied in two visits.
On the first visit, we will thin the natural tooth and take an impression
of your teeth, so the veneers can be custom-made by a laboratory.
On the second visit, we apply a mild etch to your teeth to roughen
them and help the veneers attach more securely. The veneers are
then applied to your natural teeth, one by one, using composite
resin cement and the bonding technique.
Things to Consider
Cosmetic dental procedures and orthodontics aren't for everyone.
Here are a few things to consider before you go ahead with bonding
bleaching, or orthodontics:
Success and Durability:
- Bonding doesn't last as long as crowns and may require touch-ups
every 3-5years. Crowns require touch-ups every 10 years or so.
- Veneers can chip or peel off if not cared for properly. Avoid
habits such as biting your fingernails and chewing on hard objects.
Time:
- Bonding is quick. Several teeth can generally be bonded in one
visit.
- Veneer treatment usually requires at least two, sometimes three,
dental visits of varying lengths.
Discomfort and After-Effects:
- You may experience minor discomfort with veneer treatment.
- Staining or decay can occur under the composite resin if the
bond between your tooth and the bonding material fails.
- Placing veneers is often an irreversible process because a small
amount of the enamel has been removed to accommodate the thickness
of the shell. Teeth may be sensitive and look unnatural until
the veneer is bonded.
- Veneered teeth must be either periodically re-veneered or crowned
if the veneers chip or peel off, or if decay develops under the
composite resin or the porcelain veneer.
Eating, Drinking, and Smoking:
- Tobacco, coffee, tea, blueberries, grape juice, cherries, and
red wine can stain bonded teeth as well as natural teeth.
- Veneers, especially those on the front teeth, can be chipped
if you are not careful when biting into hard or chewy foods.
Cost:
- Cosmetic dental procedures might not be covered by dental benefit
plans. If you have your teeth bleached or bonded, you may have
to cover the costs yourself
