Dental Sealants Sydney

dental sealants

 

A dental sealant (also called a pit and fissure sealant) is a plastic, professionally-applied material that is put on the chewing surfaces of back teeth to prevent cavities. Sealants provide a physical barrier so that cavity-causing bacteria cannot invade the pits and fissures on the chewing surfaces of teeth.

 

Why should my child get dental sealants?

Since the early 1970s, childhood dental caries on smooth tooth surfaces (those without pits and fissures) has declined markedly because of widespread exposure to fluorides. By 1986-1987, approximately 90 percent of the decay in children’s teeth occurred in tooth surfaces with pits and fissures, and almost two-thirds were found on the chewing surfaces alone. Dental sealants have been shown to prevent decay on tooth surfaces with pits and fissures. Sealants have been approved for use for many years and are recommended by professional health associations and public health agencies.

 

When should my child get dental sealants? 

First permanent molars erupt into the mouth at about age 6 years. Placing sealants on these teeth shortly after they erupt protects them from developing caries in areas of the teeth where food and bacteria collect. If sealants were applied routinely to susceptible tooth surfaces in conjunction with the appropriate use of fluoride, most tooth decay in children could be prevented.

Second permanent molars erupt into the mouth at about age 12 years. Pit and fissure surfaces of these teeth are as susceptible to dental caries as the first permanent molars of younger children. Therefore, young teens need to receive dental sealants shortly after the eruption of their second permanent molars.

 

Do dental sealants replace fluoride?

No. Fluorides, such as those used in community water, toothpaste, gels, varnish, and mouthrinse also help to prevent decay. Fluoride works best on the smooth surfaces of teeth. The chewing surfaces on the back teeth, however, have tiny grooves where decay often begins. Sealants keep cavity-causing bacteria out of the grooves by covering them with a safe plastic coating. Sealants and fluorides work together to prevent tooth decay.

 

How do sealants fit into a preventive dentistry program?

Sealants should be used as part of a child's total preventive dental care. A complete preventive dental program includes use of sealants, fluoride, plaque removal, careful food choices, and regular dental care.

 

Why is sealing a tooth better than waiting for decay and filling the cavity?

Sealants help maintain sound, intact teeth. Decay destroys the structure of the tooth. Each time a tooth is filled or a filling is replaced, additional tooth structure is lost. Fillings last an average of 6 to 8 years before they need to be replaced. Appropriate use of sealants can save time, money and the discomfort associated with dental treatment procedures.

 

Are dental sealants just for kids?

The potential to develop pit and fissure decay begins early in life, so children and teenagers are obvious candidates. But some adults at high risk of decay can benefit from sealants as well. Your dentist can tell you if you would benefit from dental sealants.

 

How are sealants applied?

Applying sealants does not require drilling or removing tooth structure. It is an easy three-step process: The tooth is cleaned with a special toothpaste. A special cleansing liquid, on a tiny piece of cotton, is rubbed gently on the tooth and is washed off. Finally, the sealant is painted on the tooth. It takes about a minute for the sealant to form a protective shield.

 

Are sealants visible?

Upon close examination sealants can be seen. Sealants can be clear, white, or slightly tinted. Because they are used only on the back teeth, sealants cannot be seen when a child talks or smiles.

 

How long will sealants last?

One sealant application can last for as long as 5 to 10 years. Sealants should be checked regularly, and reapplied if they are no longer in place.

 

Do dental sealants replace fluoride?

No. Fluorides, such as those used in community water, toothpaste, gels, varnish, and mouthrinse also help to prevent decay. Fluoride works best on the smooth surfaces of teeth. The chewing surfaces on the back teeth, however, have tiny grooves where decay often begins. Sealants keep cavity-causing bacteria out of the grooves by covering them with a safe plastic coating. Sealants and fluorides work together to prevent tooth decay.

Dental Sealants and Fissurotomy

 

The natural structure of teeth is uneven and normal teeth have pits and depressions in them.  These can be on the sides of teeth or they could be on the chewing surface of teeth. Pits and fissures on the chewing surface cause food particles to get entrapped in them and if these remain there for a longer time, bacteria can grow on them and eat into the enamel of the teeth causing them to decay. The main cause of tooth decay in children has been found to be this.

 

One of the preventive methods to stop tooth decay is the use of dental sealants. Dental sealants are hard inert plastic materials that are applied to the pits and fissures in teeth so that these are filled up and food cannot be trapped there to cause decay. These dental sealants have been widely tested and approved by public health agencies and medical associations as being completely safe for use. The use of dental sealants has shown a marked decrease in the incidence of tooth decay in children.

 

Since keeping molars at the end of the jaw clean where the tooth brush reaches with difficulty is a slightly difficult task for children. This is the cause for decay of these back molars and preventing the decay by dental sealant treatments Sydney rather than more extensive and expensive treatments after teeth have decayed is a much better option.

 

Dental sealant treatment can start as early as 6 years of age when the first molars at the back make their appearance. By covering the pits in the molars with dental sealants, the hard to reach molars are protected from decay causing bacteria growing on the chewing surface of the tooth as there are no depressions where food can be trapped. Dental sealants are not visible as they are transparent, white or slightly tinted in color. Since they are applied to the last molars, one cannot see them even when the child laughs.

 

Dental Sealants treatments Sydney are ideal preventive dental care treatments for children as they are non -invasive in nature and there is no drilling involved. The treatment is simple and takes only a minute or two as it just involves cleaning the surface of the tooth and applying the sealant on to the surface.

 

Dental Sealants are used as part of a child's total preventive dental care. A complete preventive dental program includes use of dental sealants, toothpaste that contains fluoride, plaque removal whenever required, careful food choices which includes reduction in sugars and sticky foods, and the most important; regular dental checkup.
