What are the Options to Fill Gaps in your Teeth

Sometimes it is not possible to save a tooth with treatment because of clinical or financial reasons. In these circumstances the tooth is extracted or removed and the question arises as to what to do about the missing tooth.

There are six options for replacing missing teeth.

1. Leave it alone

2. A removable partial denture and flexi partial denture

3. A conventional fixed dental bridge (fixed denture)

4. An adhesive resin retained maryland bridge

5. A dental implant

6. An orthodontic treatment combined with any of the above.

Leave it alone

It is not always necessary to replace a missing tooth. The decision to replace it is based on a number of factors, including appearance, loss of function, health of surrounding teeth and bone and opposing teeth, whether there are other missing teeth and financial considerations. You would be surprised how often the best course of action is to leave it alone.

Removable partial denture and flexi-partial denture

The least costly and most common option for replacing a missing tooth is to have a removable partial denture, usually made from a combination of a metal called chrome cobalt and acrylic. Flexi partial dentures, made from flexible nylon resin, are gaining in popularity with dentists and patients because of greater comfort and aesthetics than chrome cobalt partial dentures. Both chrome cobalt and flexi partial dentures are fairly easy for the patient, requiring very little preparation and several teeth can be replaced if required. Appearance is good but patients can take a while to adjust to having a metal or plastic object in their mouth.

Conventional fixed dental bridge

The third option for replacing a missing tooth is a conventional fixed dental bridge (sometimes referred to as a fixed denture). The procedure is more expensive and takes a number of visits to complete.  A disadvantage is that the healthy teeth on either side of the missing tooth require extensive removal of tooth tissue with a dental drill to enable a mold to be taken. The mold is taken to a dental laboratory and a dental bridge is constructed of porcelain and gold. To replace one tooth the bridge will consist of three units, two crowns to fit over the existing teeth and a third to fit into the missing space all joined together by a precious metal framework. More than one missing tooth can be replaced. The result is usually very good with the appearance and fit very life-like. You can expect a lifespan of at least five to ten years. There is a moderate risk of root treatment being required on the crowned teeth.

Adhesive resin retained maryland bridge

An adhesive resin retained dental bridge, sometimes referred to as a maryland bridge, is less expensive and less treatment invasive than a conventional fixed dental bridge. There is less removal of tooth tissue so there is less damage to surrounding teeth. It is useful when replacing a single tooth. It is more successful when placed in the upper jaw (over 80% success after 10 years) and less successful in the lower jaw because of a tendency for slight natural tooth movements. This type of bridge consists of a porcelain crown (pontic) fused to a metal framework, which is specially treated so that it can be glued with an adhesive resin to the back of the teeth on either side of the missing tooth. A de-bonding (loosening) of the bridge, if it happens, can be quickly corrected by cleaning the metal framework and reapplying an adhesive resin.

Dental implant

Another option for replacing a missing tooth which is gaining momentum with dentists and the public, is a dental implant. A dental implant is made from a precious metal, called titanium, in the shape of a root. This is screwed into the bone, where it integrates into it like a root. Implants have a number of uses. They can be used to support a crown, a bridge or a denture. They can also be used in orthodontic treatment. They are ideal for use in a situation where a tooth replacement is necessary but a bridge cannot be used. They feel very natural and surrounding teeth do not need any preparation. The disadvantages are high cost, the required surgery and the fact that many dental visits are required over a number of months.

Combined orthodontic treatment (braces)

Orthodontic treatment on its own or combined with other treatments can be used to help close the gap caused by the loss of one or several teeth.

What is a Dental Bridge

What is a Dental Bridge?

Dental bridges, like implants and partial dentures, are used to replace missing teeth.

A dental bridge is effectively a false tooth which is fused between two porcelain crowns to fill in or ‘bridge’ the area left by a missing tooth. The two crowns that hold the bridge in place are attached to your teeth on either side of the false tooth. The result is a fixed bridge. There are several types of fixed dental bridge including conventional fixed bridges, cantilever bridges and resin-bonded bridges.

Conventional bridges require shaping of the teeth surrounding a missing tooth. Cantilever bridges also require shaping, the difference being that cantilever bridges are used when there are teeth only on one side of the open space and are therefore more suitable in areas of the mouth that are under less stress, such as your front teeth. With both conventional and cantilever bridges, crown(s) are placed on the shaped teeth and attached to an artificial tooth (called a pontic). Resin bonded bridges require less preparation of adjacent teeth and are often used to replace front teeth, provided the gums are healthy and the surrounding teeth are in good shape.

A well cared for bridge will last as many as ten or more years. They can reduce your risk of gum disease, help correct bite issues and even improve your speech. Generally dental implants are longer lasting and have the advantage that adjacent teeth are preserved. Your dentist at Reva Dental Kilkenny will discuss all your options with you in full including the costs involved in each alternative treatment option.

Dental Bridges Consultation & Treatment Planning

Once you and your dentist have determined that a bridge is the best replacement for your missing tooth or teeth, you will be advised of the different materials that can be used to fabricate the dental bridge. Bridges can be made of different materials such as non precious metals, metals, gold and porcelain. Material choice will depend on where in the mouth the bridge will be placed, the strength of your bite, whether or not you grind your teeth (bruxism) and other factors. For example if you have a very strong bite and the bridge is being placed at the back of the mouth where appearance is not crucial, we can make the whole bridge from zirconia which is an extremely durable white material, but not a perfect match for your own tooth. Usually the best appearance and longest lasting results will come from a porcelain and gold combination. This has gold on the inside for strength and fit, and porcelain on the outside for the best appearance.

Your Reva dentist will take X-rays and impressions of the area requiring a bridge. Depending on the number of consecutive teeth you are missing your bridge could be three or more units; two crowns that are cemented to the teeth on wither side of the space (called abutments), plus one or more false teeth. (called pontics) to fill the space. Additional impressions will be taken after your dentist prepares the abutment teeth for the bridge.

The Dental Bridge Procedure

During your visit to Reva Dental your dentist will prepare the teeth which will be used to support the bridge. If the support teeth are decayed  your dentist may need to repair these before proceeding. Next, a putty-like material is used to create an accurate model of your teeth. Your bridge is fabricated based on this model by our highly skilled lab technicians so that it precisely fits the prepared teeth. While your bridge is being fabricated at our laboratory you will be fitted with a temporary bridge until your permanent bridge is ready.

Dental Bridge Recovery & Post Procedure Care

Once your permanent bridge has been fitted your dentist will discuss how to maintain the performance and longevity of your restoration. A special bridge floss threader can help to clean the areas surrounding the bridge and between the pontic and underlying gum tissue. Proper brushing ideally using an electric toothbrush and fluoride toothpaste should be done at least twice per day as normal.

If you have replaced a partial denture with a porcelain bridge, or indeed for whatever reason you have had a bridge restoration at Reva Dental, why not also discuss our teeth whitening options with your dentist to further lift the appearance of your smile.
