Posterior Gold Crowns
It takes two or more appointments to restore a damaged
tooth with a gold crown. That's because a crown is fabricated
in a dental laboratory to precisely fit your tooth.
The first visit
We want the entire procedure to be comfortable for you,
so the first thing we do is make sure your mouth is thoroughly
numb. We then use the handpiece to shape the tooth and
remove any decay. To create models of your teeth on which
the dental laboratory will
fabricate your crown, we must first take impressions of
your mouth. Sometimes, to help us take a more accurate
impression, we put a small piece of string in the space
between the tooth and the gum. This allows us to gently
push the gum away from the tooth. After the impressions
are complete, we place a temporary crown, which you’ll
wear for the several weeks that it takes the dental laboratory
to fabricate your new crown.
The second visit
During your next visit, we remove the temporary crown
and place your new crown. We check the fit and your bite.
When everything
looks good, we cement it in place and you’ll have
a new gold crown.

Post and Core
Sometimes, when a tooth has broken off due to fracture
or decay, there’s simply not enough of your natural
tooth remaining to place a crown. Fortunately, we can
replace the missing portion and save your tooth by placing
a post inside your tooth, which will
then anchor a filling material, called a core.
The post and core procedure in dental
clinic in mumbai india
The first step in placing a post is performing root canal
therapy on the tooth to remove the infection and shape
the root canal to receive the post. We’ll use a small
instrument called a dental file to shape the top of the
root canal, select a post, and then cement or bond it
in place. Depending on the situation, we may use posts
made of metal, fiber-reinforced plastic, or carbon fiber.
After the post is in place, we fill the tooth with the
new core material. Once it has hardened, the core material
is shaped and prepared to receive a crown. We then take
an impression of your teeth so that a dental laboratory
can custom-craft a crown that will precisely fit your
tooth.
We’ll place a temporary crown to cover and protect
the prepared tooth while your custom crown is being created.
To ensure the proper fit of your final crown, it’s
important that your temporary crown stay in place, but
on rare occasions, it may become loose or fall out. If
this happens, keep it and call us and so we can re-cement
it. You’ll also need to be careful when you floss,
removing the floss from the side of your tooth rather
than the top so you don’t pull off the temporary.
Avoid eating hard or sticky foods (especially gum), and
if possible, chew only on the opposite side of your mouth.
At your next appointment, we’ll remove the temporary
crown and replace it with your new custom crown.

What Is a Core Buildup?
Restoring a tooth before placing a
crown
Fracture or decay can cause a portion of a tooth to break
off, and in some cases, there’s simply not enough
tooth left to place a crown. Fortunately, we can replace
the missing portion and save the tooth by building it
up with one of the new resin/plastic filling
materials. Once the tooth is built up, we can place a
crown. Building up a tooth before placing a crown:
• strengthens the tooth
• provides better retention for the crown
• may reduce sensitivity by providing insulation
for the sensitive inner pulp
The procedure at dental mumbai
We want the entire procedure to be comfortable for you,
so the first thing we do is make sure your mouth is thoroughly
numb. Then, we use the dental handpiece to remove any
decay. To prepare the tooth for the resin filling material,
we apply a mild etching solution. Next we build up the
tooth by carefully placing the resin filling material,
layer upon layer. Finally, the filling material is hardened
with a high-intensity light. A core buildup is necessary
before crowning teeth that have been significantly damaged
due to decay or fracture.
