| 01)
What is Bonding?
The term bonding is used to describe procedures
where tooth-colored dental resins and composites are used.
Direct bonding techniques can be used to change the shapes
and colors of teeth as well as to close unattractive spaces.
It can also be used to repair
chipped or broken teeth or even to cover up unsightly stains.
Unlike crowns or caps, direct bonding requires only a minimal
amount of tooth reduction thus making it a very conservative
procedure.
02) How does Bonding work?
After slight preparation, the tooth is etched
with a weak phosphoric acid solution to create a more porous
and rougher surface for increased bonding strength. Next,
a composite (plastic) resin in placed on the tooth and shaped,
contoured and hardened with a special curing light. It is
then further shaped and highly polished creating a very natural
appearance. The procedure usually requires only one visit
and is not painful.
03) How long will
Bonding last?
The bonded composite has an average life of four to eight
years, and often lasts depending how and where in the mouth
it is applied and how it is maintained. The area can be touched
up and even re-bonded over time as necessary.
04) What is Cosmetic Contouring?
Cosmetic contouring (or recontouring) is
the reshaping of a patient's own teeth. This process involves
removal of a very small amount of tooth structure to help
achieve a more desirable appearance. Chipped or fractured
areas are smoothed out and specific angles or edges can be
rounded or squared to alter the way your smile looks.
05) What can Cosmetic Contouring
do for me?
Contouring can create better alignment or
create a more feminine or masculine appearance. It is sometimes
done to prevent chipped areas from getting worse. Recontouring
of the teeth is generally done with no discomfort to the patient
and no anesthetic. Often it is done in conjunction with bleaching
as a very conservative and inexpensive approach to a beautiful
smile.
06) What are Implants?
Dental implants are metal anchors placed
in the jaw bone underneath the gum tissue to support artificial
teeth where natural teeth are missing. Unlike other types
of tooth replacements, such as removable dentures or fixed
bridges that are cemented to remaining teeth, dental implants
are actually placed ("implanted")into the jaw bone
under the gum tissue. These implants are usually made from
a space-age metal called titanium, which is readily accepted
by the body, and artificial teeth that look like natural teeth
are then attached to the implants. Accepted by the American
Dental Association, dental implants have been used for many
years, and hundreds of thousands have been placed. Due to
a phenomenon known as "osteointegration" meaning
that bone actually attaches itself to the implant, these anchors
provide a strong foundation that allows people with missing
teeth to chew efficiently and comfortably.
07) Who needs Implants?
Anyone who is missing teeth and can benefit
from increased chewing efficiency, and improved appearance
or speech, is a candidate for dental implants. Implants can
be the solution when it has become difficult or impossible
to wear a removable denture. Portions of the jaw that are
missing due to an accident, disease, or birth defect can often
be reconstructed using implants.
08) Am I a candidate for Implants?
You are a candidate if:
you have enough jaw bone, and dense enough bone, to secure
the implants
you do not have a disease or condition that
interferes with proper healing after implant surgery (e.g.
uncontrolled diabetes, or radiation/chemotherapy for treating
cancer)
A discussion with your oral and maxillofacial
surgeon and restorative dentist (the dentist who will make
your new teeth) will determine if you are a candidate for
dental implants. As a rule, age is not a barrier to implant
treatment if you are in good health. In fact, thousands of
people of all ages are turning to dental implants to replace
a single missing tooth, several teeth, or all teeth.
09) What is a Bridge?
A missing tooth or teeth can create an unhealthy
situation over time. It is very important to restore these
gaps. When one or more teeth are lost or missing, the neighboring
teeth can shift, tip or even "super-erupt" into
the space. Teeth that have drifted from their normal and healthy
position are often more susceptible to decay and gum disease.
Further, this movement can lead to changes in a patient's
bite that can ultimately put stress on the jaws, muscles,
teeth and temporomandibular joints (TMJ). Over time this can
affect a patient's ability to chew and may even change the
facial appearance depending on the location and number of
missing teeth.
10) Is a Bridge permanent?
There are two ways to replace a missing tooth
or teeth: fixed and removable. A bridge is a permanent or
fixed replacement, while a denture is a removable replacement.
A bridge consists of replacement teeth (one or more) that
are attached to crowns on the adjacent teeth. The replacement
teeth are shaped and contoured to blend in with the natural
teeth in the mouth.
11) How long does this procedure
take?
This procedure takes two or more visits to
complete. At the first visit, the adjacent teeth are reduced,
an impression is taken and sent to a dental laboratory for
fabrication. At the second visit, the bridge is fit and placed
permanently in the mouth. Like crowns, bridges can be made
from variety of materials for strength and esthetic appearance.
While it should always be discussed with your dentist before
treatment, a fixed restoration is generally considered to
be the favored solution for tooth replacement.
12) Silver fillings are too visible,
what are my other options?
Natural tooth-colored fillings have become
widely accepted and are often used in place of metallic restorations
where aesthetics is a primary concern. There are even studies
that show that in some cases, use of certain tooth-colored
materials can strengthen a tooth, making it a better choice
than the metallic predecessor - amalgam. Two basic types of
tooth-colored restorations are used: composite and ceramic.
13) What is a Composite Restoration?
Composites have been used for many years
however their chemical make-up has changed and improved exponentially.
The bonding agents used to make the composites adhere to the
tooth have improved just as dramatically. Because of the improvements,
the use of composites has become widely accepted by dentists
and the indications for their use are more numerous. They
are being used to close undesirable spaces, improve the shape,
size and color of a tooth, replace an unsightly amalgam restoration,
cover abraded or worn areas of a tooth (usually at the gum
line) and to cover stains. Composites can also be used to
protect thermally sensitive areas and to repair and strengthen
broken teeth.
14) How They Are Placed?
Once the tooth has been prepared and all
decay removed, chemicals and materials are placed on the tooth
to increase bond strength and to protect the tooth. Next,
the composite material is placed incrementally into the tooth
and hardened by exposure to a special curing light. The restoration
is then contoured to fit the bite and then is highly polished.
These fillings require a bit more time than the silver fillings
because of the number of steps involved. Composite fillings
can also be a bit more sensitive, at first, to extreme hot
and cold and they may discolor over time if the patient smokes
or drinks a lot of coffee, tea or cola. They can also be more
expensive and some composites may wear faster than silver
fillings; however, they yield a much more natural and aesthetic
result.
Ceramic fillings, like composites, come in
several different types that can be used for different situations.
Ceramics are typically used for the larger and more broken
down areas. In these cases, an inlay or onlay to cover more
of the tooth's surface may be indicated. These restorations
are indirect because they require two visits and fabrication
by a dental laboratory. The ceramic restorations are considerably
more expensive and therefore simple, one-visit composite fillings
are typically used instead. Ceramic restorations are much
more durable and will not stain. Naturally speaking, the final
result with ceramics is spectacular.
15) What are Veneers?
Veneering a tooth means to cover its facial
or front surface. It is actually very similar to placing acrylic
fingernails on top of natural nails. Veneers are used to enhance
shapes and colors of teeth as well as to close spaces between
teeth and to cover up significant stains such as those caused
by tetracycline.
16) What is the difference between
direct and indirect Veneers?
There are two types of veneers: direct and
indirect. Direct veneers are done in a single visit and with
a composite or plastic material. Indirect veneers are usually
done in two visits and require a dental laboratory to fabricate
the final restoration. The indirect veneer can be either a
composite material or more commonly, a porcelain material.
Due to the advancements in the porcelain substrates and the
bonding materials used to place them, they are often used
in place of crowns for a more conservative and natural looking
smile.
17) What does Veneering a tooth
involve?
First Step
During the first visit, a local anesthetic is used and the
tooth or teeth are reduced by approximately 0.5mm - 2.0mm.
An impression of the teeth in this state is then taken and
sent to a dental laboratory for fabrication of the veneers.
This usually takes one to two weeks to complete. A temporary
restoration may or may not be placed depending on the amount
of reduction necessary. There may or may not be slight sensitivity
to hot and cold during this period.
Second Step
At the second visit, a local anesthetic may be used for the
patient’s comfort in seating the veneers. After thoroughly
cleaning and preparing the teeth, the veneers are placed with
a resin material and cured or hardened with a special curing
light.
18) How long will Veneers last?
There are many different variations of porcelains
used today and this should be discussed with the dentist ahead
of time. Typically, the porcelains should last about 15 years,
however, with proper care and maintenance, they can last longer.
Porcelain veneers resist staining, reflect light and are among
the strongest and most natural looking restorations available.
19) What is Tooth Whitening (Bleaching)
and is it safe?
Bleaching is a very conservative and non-invasive
approach to creating a brighter and more appealing smile.
Teeth can often take on a darker and unattractive appearance
with age or from contact with staining substances. The discoloration
can be caused by tobacco, coffee or tea, juices, poor hygiene,
genetics, and natural aging.
20) How is it done?
There are two commonly used methods for bleaching:
at-home and in-office. Both begin with an office consultation
to determine if the patient is a good candidate for the bleaching
process. The at-home technique is the most popular and least
expensive. The in-office method allows the dentist to place
a higher concentration of bleach over the teeth.
At-Home Method
A custom mouth piece or "tray" is made to fit your
teeth by the dental office. The tray fits over the patient's
teeth and holds the bleaching material against the teeth for
a specified period of time. There are different concentrations
of bleach that are worn via the tray for one to five hours
per day for an average of 10 to 14 days. The regimen will
be determined by the dentist and may differ for each patient.
If the teeth become more sensitive to hot and cold, a "desensitizing"
material may be used in the same tray on alternating days.
Results are usually excellent with this method.
In-Office Method
The gum tissues are covered to protect them from being irritated
by a higher concentration of the bleaching material. The bleach
is then activated by a high intensity light or a laser to
accelerate the process.
21) What About Over-The-Counter
Options?
Both at-home and in-office treatments are
considerably more effective than the whiteners available at
retail. The over-the-counter products have much lower concentrations
of peroxides and ill-fitting trays that can cause damage to
the teeth and gums. |
