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:
1. Porcelain fused to metal (PFM) dental crowns
2. All porcelain dental crowns
3. 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.

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:
1. 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.
2. 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.
3. 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
4. Be careful about chewing toffees, gum, grainy
rolls and tough food in this area
5. See your dentist for regular professional check-ups
and cleanings.
