Dental Crown
A dental crown or dental cap is a custom made
restoration that covers a tooth with sustained
significant loss of structure. They are analogical
to being a thimble capped over your finger. Dental
crowns are used to restore teeth to a certain
shape and size. They provide strength and improves
the appearance of the tooth.

Benefits of Dental Crowns
- Protects severely
damaged tooth or tooth weakened by decay, fracture,
large fillings or root canal therapy from fracturing.
Teeth with large fillings tend to "flex more"
forcing the tooth apart possibily causing stress fractures
- Holds together cracked or weaken
teeth and seal the tooth from decay
- Covers discolored and irregularities
in teeth in improving cosmetic appearance
- Helps preserve the natural function
and position of the teeth
- Restores tooth with large decay,
cavities or filings
- Supports the replacement teeth in
a bridge
- Restores and maintains natural bite
- Covers a dental
implant
- Restore your smile
Types of Dental Crowns
There are three basic types of materials for
dental crowns:
- Porcelain fused to
metal (PFM) dental crowns
- All porcelain dental crowns
- All metal dental crowns (Gold)
Porcelain fused to metal (PFM) dental crowns
and all porcelain crowns are tooth colored crowns.
PFM dental crowns offer the best combination of
aesthetics and durability. PFM dental crowns are
usually used to restore back teeth where the forces
of chewing and grinding are strongest. All porcelain
crowns are the most aesthetic and are used primarily
used for front teeth where the need for strength
is not as critical. Gold dental crowns are the
most durable and offer the most precise fit. Gold
dental crowns does not chip.
The all-ceramic porcelain crowns used at Bangkok
International Dental Center include the IPS Empress
Esthetics crowns from Ivoclar Vivadent and Procera
NobelEsthetics from Nobel
Biocare.

Recovery Expectations

may cause some minor tenderness in the area. Some individuals
may experience sensitivity in teeth. This
sensitivity will disappear gradually over a few days
to weeks.
Postcare Instructions for Dental Crowns
- Avoid chewing on or eating hard
foods on the restorations for 24 hours from the time
they were cemented
- To help with discomfort or swelling
rinse your mouth 3xd with warm salt water. (1tsp.
of salt in 8oz of water)
- Keep crown area clean to maintain
tissue compatibility (the contour of the prosthesis
must allow the surrounding tissue to conform to a
natural, healthy position)
- Some sensitivity in teeth
may be experienced by certain patients. This sensitivity
will disappear gradually over a few days to weeks.
If teeth are sensitive
- Avoid hot, cold or acidic food
and beverages

directed as long as there is no medical contradiction
based upon your medical history

Care for Dental Crowns
Dental crowns require the same regular and consistent
home and professional dental care, as your natural teeth
to prevent decay at the tooth-dental crown junction.
To provide optimum longevity for your restorations,
please follow the home care tips below:
- Brush after eating and before bedtime
around the crown with a soft toothbrush, especially
where the crown meets the gum line. At the gum line
harmful bacteria can be harbored to cause decay and
gum disease.
- Floss at least once to twice a
day. Use the proxy brush or floss threader to remove
plaque under and around these areas to maintain good
oral hygiene. Buildup of food debris and plaque on
your teeth and gums can become infected.
- Rinse with fluoride rinse before
bed. Swish the fluoride rinse vigorously in your mouth
for at least one minute. Do not swallow any of the
rinse and do not eat or drink anything for 30 minutes
- Be careful about chewing toffees,
gum, grainy rolls and tough food in this area
- See your dentist for regular professional
check-ups and cleanings
