Crowns, Bridges & Veneers

Veneers, crowns, bridges and implants are often used to address patients' aesthetic or functional concerns. However, there are a wide choice of indications for these treatments that, can range from compromised or weakened teeth to filling missing gaps.

What Are Crowns?

It is a restoration which covers (like a cap) on the tooth, to restore the tooth to its normal shape and size, which gives the tooth the strength and improves the overall appearance of the tooth. Crowns(prosthetic) are made up of metal substrates, or new all-white restorative materials. The dentist would suggest, that it is necessary to have a crown fixed when a tooth is generally broken, and also when replacing a tooth with a filling that won't help. If the tooth is cracked, then the job of the crown is that it holds the tooth together to seal the crack, so that it does not damage the tooth. Crowns also play a vital part,and are used to support large fillings, when there is isn't enough tooth remaining, and attach a bride, to help protect the weak tooth from fracturing, which also helps to restore the fractured teeth,where the cover is badly shaped or discoloured and also helps to protect a root canal filled tooth with added strength.

What is the procedure of the Crown?

First the dentist will remove any decay or weak areas, then the dentist will re-shape the tooth structure, to meet the proper crown preparation and design,if the need arises, then a restorative material, usually made of composite resin is added to the remaining tooth structure to ensure that the prosthetic crown which will have a good foundation, this procedure is called a "build-up"

If there is dental decay that is found to have buried itself deep, where the dental pulp is affected, then a root canal procedure is essential prior to the completion of the crown/bridge procedure, this is to avoid further complications with pulpal infections after the procedure is carried out.

After preparation of the tooth, the impressions of the teeth and gums are sent to the dental laboratory for crown fabrication. At the next visit, the dentist cements the crown permanently onto the tooth. At the next visit, the crown is placed on the tooth, and adjustments may be required to know the exact fit, so that the crown will feel comfortable in the mouth and will conform to the bite. When the crown fits accurately and comes in contact with the neighbouring teeth, the crown is then cemented on to the tooth.

Will it look natural?

Yes it will. The dentist main aim, is to create the crown in such a way that it looks natural. The reason behind this, the impression that is taken before the crown being cemented. To also have the tooth look natural, there are certain factors which are considered, such as colour shape, bite and length of the natural teeth, anyone of these factors can hamper the appearance of the person. If you have a personal cosmetic look in mind for your crown, discuss it with your dentist on your initial visit . When the procedure is finally complete your teeth will look more attractive and stronger. If the crown is made of metal(vitallium) it will have a metallic finish, however it will also resemble a normal tooth in its shape & size.

A Cap and a Crown What is the difference between them?

There is absolutely, no difference between a cap and a crown at all.

What is the duration of a crown? How long does it last?

Crowns last for about 5-8 years approximately, it is also important to maintain good oral hygiene and with supervision most of the crowns will last for a longer period of time. There could be some damaging habits associated with the crown, which is biting, grinding your teeth, chewing ice, or even biting fingernails, which may decrease the longevity of the crown, it can also affect the fabrication of the crown & the life of the crown.

What care is required for a crown?

To prevent the crown from any damage, or fracture, try to avoid chewing hard foods, like ice or any other hard substance. You will also have to avoid grinding your teeth, besides visiting the dentist if you are uncomfortable, cleaning between the crown is also necessary, flossing also, it is best to check with your dentist what type of brush is required to remove plaque from the crown area where the gum meets the tooth. If there is plaque in the area it can cause dental decay and gum disease. Regular check up at the dentist must be done, or other wise bacterial assault can cause decay and makes dental care necessary which may cause the restorations to fail.

Why should I get a Bridge?

What is a bridge?

Without the use of a denture, or a dental implant an dental appliance which is made up of multiple crowns, is called a bridge, it helps to replace one or more natural missing teeth, thereby bridging the space between the two teeth. The bridges are then,cemented into the place on the "abutment" teeth i.e. it surrounds the teeth on either side of the space or span from which the bridge takes support. Teeth that is called 'pontics' which connects the crowns on abutment teeth together and replaces the missing teeth. Unlike removable partial dentures, and bridges which cannot be taken out of the mouth of the patient.

Who should get a bridge?

A good candidate for a bridge, is a person who has missing teeth and maintain good oral hygiene. Abridge is the best solution to missing teeth and a natural choice to fill the space in the mouth. If this space is left unfilled, then the space that surrounds the neighbouring teeth can drift out of position and can cause the teeth and gums to become prone to tooth decay and gum disease, which can cause further tooth loss. When the bridges are fixed, they not only correct the altered bite, but also improve the chewing ability and speech which also safeguard the appearance, by preventing the collapse of the facial features which can cause premature wrinkles and age lines.

What types of bridges are there?

The most common bridge is known,as the traditional bridge, and another popular design is the resin bonded, or it is known by another name "Maryland bridge" which is primarily used for the front teeth, it also usually most economical choice when the abutment teeth are healthy and don't contain large fillings. The pontic is then fused to the metal bands, that can be bonded to the abutment teeth with a resin cement and hidden from the view of reducing the amount of preparation on the adjacent teeth.

Another bridge known as the cantilever bridge, which can be used if there are teeth on only one side of the span, which involves anchoring the pontic to one side over, or one or more of the natural, teeth which are adjacent.If there are not adjacent teeth left to act as anchors, then the dentist will recommend an implant known as a metal post that is surgically embedded into the bone and is capped with a crown as an abutment. In various cases, where the span is large, a removable partial denture which is recommended or even an implant-supported prostheses.

What can be done to brighten my teeth

Tobacco, coffee, cavities, aging and drugs can stain teeth. Treatment for discoloured teeth depends on the magnitude of the stain; remedies appear here in order of increasing intensity

  1. To reduce and prevent stain, you need to Brush and floss regularly
  2. Try whitening toothpastes. Many tooth pastes are advertised in the market with tooth whitening effects, however,these toothpastes,don't necessarily help make teeth white. It is known that very few whitening toothpastes have undergone a type of clinical trail, and there are ones that are too harsh and also can damage teeth or make them very sensitive.
  3. Use regular dental cleanings, which can remove many foods and tobacco stains. No matter how many times you clean your teeth, the stains which are left by tetracycline or systemic disease due to pigmentation lie inside the tooth, and you will have to take more aggressive measures to fight against it.
  4. You can consider two options, one is in -office and also at home treatment, for bleaching your teeth. The dentist will perform in-office treatments by coating the teeth with a bleaching agent, and by using periodic flashes of light to activate the solution. The treatment lasts up to 30-60 minutes and the complete procedure does often require several appointments. In home treatments, the patient wears a mouth guard,which is fitted with a bleaching gel to a maximum of 2 hours a day for, about two weeks, depending upon how much the teeth are stained.
  5. There is another solution, think about getting veneers which are custom-made shells bonded to the teeth with resins. This procedure does often require removing a small amount of tooth structure, which is most invasive, as well as an expensive option.

What are Veeners?

Veneers are made up of ultra-thin shells of cream(porcelain)or a composite resin material, which are bonded to the front teeth. This is a kind of procedure requires little or no anaesthesia and can be an ideal choice of improving the appearance of the font teeth. Veneers are also placed to mask discolourations, and to brighten teeth and to improve a smile

What is an option for replacing defective filling?

There are various options, material choices and techniques which are used today for restoring teeth,to look health white and beautiful. The dentist recommends that instead of using traditional sliver amalgam fillings, now patients can choose to have their worn or decayed teeth repaired with a new ceramic and composite dental material which are equal or also surpass in strength but look natural.

At Dr. Dubey's clinic, our team is committed in providing our patients with advanced and hightec care as possible. We use a CEREC all-ceramic restoration which is ideal replacement for a large old failing restoration in a load bearing(chewing)tooth as it is of superior aesthetics and strength compared to a sliver amalgam or tooth-coloured composite filling. The dentist would do a 3D scan of your tooth, as CEREC restorations are custom designed and then milled from an enamel-like porcelain material so that they look and feel natural, and these fillings would last longer, compared to traditional filling material. The advantage of CEREC all-ceramic restorations at Dr. Dubey's Clinic, is that they can be completed, in just one visit rather than the need for repeated and additional ill-tasting impressions,temporary restorations, and unnecessarily a second appointment for delivery of the restoration.

About replacing missing teeth

Missing teeth, can affect the way the rest of your teeth bite together. The remaining teeth would tilt or drift into the gaps, as this makes room for food particles, to get easily trapped in the spaces, increasing the risk of tooth decay and gum disease,and when more than one tooth is missing it can make your cheeks look saggy, and affect your speech and appearance.

The advantage of replacing teeth can help match the colour and also make your teeth look natural that that of the normal teeth.

Treatment options

There are various treatment and options available to replace missing teeth

  • Bridges: These are false teeth which are fixed onto adjacent natural teeth
  • Dentures:(false teeth) Are removable plastic or metal framework carrying false teeth
  • Dental Implants: They are metal "pegs" placed in the jawbone, these dentures or bridges are clipped and screwed on the top of the dental implants.

The dentist will decide the best option, and the appropriate treatment for you, depending on the condition of your natural teeth and the number of missing teeth.
