What are Fissure Sealants

What are Fissure Sealants?

What if you could prevent tooth decay from forming in your own or your children’s teeth and avoid having to endure the dentist drill? Preventing tooth decay before it appears can mean less pain and less money spent in the long run. Proper brushing and flossing are essential to removing plaque on the smooth surfaces of teeth to help keep your mouth cavity free. But did you know that the indentations on the chewing surfaces of the back teeth, called pits and fissures, are one of the most common places that tooth decay occurs and also one of the most difficult to clean properly? Toothbrush bristles often cannot reach the tiny grooves in these teeth to remove plaque effectively. How can we prevent decay from occurring in these pits and fissures that our toothbrushes cannot reach? One effective solution is a dental sealant.

What are dental sealants?

A sealant is a plastic film-like material that is applied to the chewing surfaces of the back teeth. The plastic material bonds to the pits and fissures of the teeth and acts as a barrier to protect the teeth from decay causing bacteria.

Who can benefit from sealants?

At Reva Dental Kilkenny sealants are most often recommended for children who have newly erupted permanent teeth. First and second permanent molars erupt into the mouth at about ages 6 and 12 years. Having sealants applied to these teeth shortly after they erupt protects them from developing cavities in areas that are difficult to clean. Adults who have existing pits and grooves in the biting surfaces of back teeth may also benefit from sealants. Also, individuals who experience frequent dry mouth may benefit from the extra protection of sealants since their teeth are often deprived of the protective benefits of saliva, which makes them especially vulnerable to cavities.

How are sealants applied to teeth?

Sealants are applied by your dentist and the procedure is simple and fast with very little, if any, discomfort. First, the teeth to receive the sealants will be cleaned and thoroughly rinsed. An acid solution or gel will then be applied to the tooth to help the sealant bond with the tooth. The sealant material will then be painted onto the teeth, much like nail polish on a fingernail, and allowed to dry and form a bond on the chewing surface of the tooth. Your dentist may use a special curing light to help the sealant material harden. It generally takes only a few minutes to seal each tooth. Once applied sealants can last from five to ten years.

How effective are sealants?

Because sealants act as a physical barrier to decay causing bacteria, sealants are nearly 100% effective in protecting teeth from cavities in pits and fissures if applied properly. A systematic review of 16 studies found that permanent molar teeth with sealants had almost 80% less tooth decay on the biting surfaces than teeth that were not sealed. Dental sealants are also cost effective (please see a list of our fees here). Having sealants applied is less than the cost of having a cavity filled.

At Reva Dental we believe that prevention is the key to keeping your mouth and teeth healthy. Be sure to brush twice a day with fluoride toothpaste containing at least 1000 parts per million of fluoride, clean between your teeth daily with floss, eat healthy foods, and visit your dentist regularly.

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.
