CROWNS & BRIDGE
|
 |
A crown is a covers or "caps" for a tooth to restore it to its normal shape and size thus strengthening and
improving the appearance of a tooth. Prosthetic crowns are made of metal, porcelain fused to metal substrates, or new
all-white restorative materials.
Crowns are necessary when a tooth is generally broken down and fillings won't solve
the problem. If a tooth is cracked, a crown holds the tooth together to seal the cracks so the damage doesn't get worse.
Crowns are also used to support a large filling when there isn't enough of the tooth remaining, attach a bridge, protect
weak teeth from fracturing, restore fractured teeth,cover badly shaped or discolored teeth or protect a root-canal filled
tooth with compromised strength.
Benefits - Replaces missing tooth structure, offers support to misshapen teeth or badly broken teeth, looks completely natural, can correct severe color discrepancies, fixes "smile" and functional chewing problems. |
The tooth is numbed and prepared for the crown by removing any decay or weakened areas. After the tooth is prepared, an
impression of teeth and gums is made and sent to our lab for the crown fabrication. On the next visit, the dentist cements
the permanent crown onto the tooth some adjustments may be required to exact the perfect fit, so that the crown will feel
comfortable in the mouth and will conform to the bite. If you have a certain cosmetic look in mind for your crown, discuss
it with our dentist at your initial visit. When the procedure is complete, your teeth will not only be stronger, but they
may be more attractive.
Crowns should last approximately 5-8 years. However, with good oral hygiene and supervision most crowns will last for
a much longer period of time. Some damaging habits like grinding your teeth, chewing ice, or fingernail biting may
cause this period of time to decrease significantly. avoid chewing hard food. You also want to avoid teeth grinding. Besides visiting your dentist and brushing twice a day,
cleaning between your teeth is vital with crowns.
Regularly scheduled examinations and hygiene appointments must be adhered
to, or the same bacterial assault which causes decay and makes dental care necessary may cause the restorations to fail. |

A bridge is a dental appliance that replaces one or more natural missing teeth,thereby "bridging" the space between two
teeth .Bridges are cemented into place on the "abutment" teeth--the surrounding teeth on either side of the space or span.
Unlike removable partial dentures,bridges cannot be taken out of the mouth by the patient.
A bridge is a device that typically consists of three units-a pontic (a false tooth) fused between two crowns that are
cemented onto the abutment teeth.
Benefits - They fill the space in the mouth left by missing tooth They not only correct an altered bite, improve the
chewing ability and speech, but they also safeguard the appearance by preventing the collapse of facial features that
can cause premature wrinkles and age lines.
If the space between the tooth are left unfilled, this space
can cause the surrounding teeth to drift out of position and can cause teeth and gums to become more susceptible to
tooth decay and gum disease that can cause further tooth loss.

For a traditional fixed bridge, the first appointment consists of the dentist reducing the adjacent abutment teeth that
will act as anchors. Impressions are made, from which a metal framework, including the pontic, is created. By the second
appointment, the final bridge is fitted over the teeth. The total treatment time is usually around one week, depending on
the type of bridge. However, because it is often difficult to match the natural shade of your teeth, the treatment time may
be longer.
Suggestions and precautions - To provide optimum longevity for your restorations and to prevent future decay and supporting-tissue
breakdown. Brush after eating and before bedtime around the bridge with a soft toothbrush, floss at least once to twice a day. On a bridge you must clean “under” as well as around the bridge.
If you do not control the buildup of food debris and plaque your teeth and gums can become infected.
Fluoride rinse is to be used before bed. Swish the fluoride rinse vigorously in your mouth for at least one minute.
Visit a dentist at
regular six-month examination periods for advice and examination of your
bridge.

Types of Dental Crowns & Bridges
There are three basic type 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 Beauty smile dentalclinic include the IPS Empress Esthetics crowns from Ivoclar Vivadent and Procera NobelEsthetics from Nobel Bio care.
Post care Instructions for Dental Crowns & Bridge
1.Avoid chewing on or eating hard foods on the restorations for 24 hours from the time they were cemented
2. To help with discomfort or swelling rinse your mouth 3xd with warm salt water. (1tsp. of salt in 8oz of water)
3. 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)
4. 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
- Pain medication be taken as directed as long as there is no medical contradiction based upon your medical history
- Use fluoride rinse and toothpaste for sensivity teeth
- Clean teeth properly
Care for Dental Crowns & Bridge
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
