Dental Crowns
Also called caps, crowns are dental restorations
that are placed over a tooth when other procedures like bonding
are simply not enough. Inlays and onlays are similar to a partial
crown, most often made of porcelain. An inlay substitutes for a
filling, while on onlay covers more than just the tooth’s
surface. An onlay usually replaces a filling and coats one or more
of the tip of the tooth.
A crown restores your tooth’s function, enhances
its aesthetic appeal and improves the health of your mouth. Crowns
can be constructed of porcelain, gold and other metals, acrylic
resin, or a mix of these materials.
Most crowns are made from porcelain fused to metal or gold. A precious
metal base is made and then porcelain is applied in layers over
it.
At the first
visit, your cosmetic dentist will shape your teeth
to stabilize your tooth structure in order to better fit
the crown. Once your teeth have been prepared for your crowns,
your cosmetic dentist will take impressions of your teeth
and send them to the dental lab for further restorations.
At this time, you and your dentist can choose the shape,
size and color of the crown. While you’re waiting for
the permanent restoration, your cosmetic dentist will insert
a temporary one inside your mouth.
At the second visit, your dentist
will take out your temporary restoration and replace it with your
new crown. After the crown has been adjusted to your tooth, an
adhesive agent is applied to permanently secure it.
When are Dental Crowns Used ?
In some cases, the dentist may need to perform a root canal
before inserting dental crowns.
If this occurs, the dentist must
construct the foundation for the dental crown after root canal
therapy. This is known as “post and core” foundation.
On your first visit, your dentist will examine and prepare your tooth by taking
X-rays. Before making your crown, your dentist will administer local anesthetics
to numb your tooth and gum tissue. The tooth is then prepared to make room for
the crown.
An impression of the tooth and neighboring teeth is made, and while the crown
is being developed, a temporary acrylic crown covers the tooth. Temporaries as
they are commonly referred to are worn until your permanent crown comes back
from the dental lab.
The impressions are sent to a dental laboratory to create the permanent crown.
This permanent crown will be returned to the dental office in 3-7 days and sometimes
sooner depending on turn around time.
At your second visit, your dentist will remove the temporary crown and examine
the fit of the permanent one. Once the crown is a good fit and colour, the dentist
will administer a local anesthetic to insert the new, permanent crown.
Why use Dental Crowns?
When a tooth is cracked, decayed, or damaged, a crown may need to be fitted onto
the tooth. Crowns can whiten, reshape, and realign existing teeth, adding to
a healthy and vibrant smile.
For instance:
You may have discoloured fillings and would like to improve the appearance
of the tooth.
You may have had a root filling which will need a crown to protect it.
You may have had an accident and damaged the tooth.
It may be needed to help hold a bridge or denture firmly in place.
The tooth may have been weakened by having a very large filling.

Pattaya
Beach is some 4 km long and faces
Pattaya Bay, the major venue from which boats
visit Pattaya’s offshore islands. The
beach is paralleled by a tree-lined promenade,
hotels and restaurants. The northern section
of the beach is largely tranquil, while the
central and southern parts become increasingly
lively, due to the shops, bars, discotheques,
and restaurants lining the streets.
