You would not place a sealant over a filling in all cases, but it can be done and in fact is indicated in some circumstances. There is considerable research to support this technique in a number of dental studies. It is true that some sealants are opaque and you cannot see through them, but you cannot see through a filling either. Placing a sealant to repair the edges of an existing filling is not going to make it any less likely that you can detect caries in the future, and in fact is often the most conservative way to address a minor defect on an existing filling. Sealants placed correctly have a proven track record - but they can't just be thrown on a tooth carelessly, with saliva contamination or inadequate light curing and expect them to work - they have to be done carefully and correctly. I do not agree with the answer immediately below, but think it is fair to let others have their opinion.


NOOOOO!!!!! should there be recurrent caries (the clinical name for cavity) the sealant will hide the cavity underneath and the dentist will not be able to diagnose the cavity without an xray. Don't seal teeth that have previous filling or a history of cavities.

Agreed - but I have just had a horrible experience with sealants, and have recently found several of my peers experiencing the same. Over time, the sealants break down, and it is not possible for a dentist to know what is lurking underneath until they are completely removed (xrays nor laser will detect decay under sealants). I had my 8 removed, and there was SIGNIFICANT damage under all my teeth. I am now doing more research but feel that there is more damage than good by getting sealants - I recommend brushing and taking care of your teeth and NOT sealing them. Don't have happen to you what has happened to me.


What was the human invention?

Teeth Sealants

What is the material used for?

The term "dental sealant" or "tooth sealant" refers to a plastic resin that a dentist bonds into the grooves of the chewing surface of a tooth as a means of helping to prevent the formation of tooth decay ("cavities


The chewing surfaces of the molar and premolar teeth have grooves - "fissures" - that make them vulnerable to decay. These fissures can be deep, are difficult to clean, and can be narrower than even a single bristle of a toothbrush. Plaque accumulates in these areas, and the acid from bacteria in the plaque attacks the enamel and cavities can develop. Fluoride helps prevent decay and helps protect all the surfaces of the teeth, dental sealants provide extra protection for the grooved and pitted areas by providing a smooth surface covering over the fissured area.

What is the benefit of the new material?

By bonding plastic resin (the dental sealant) into the grooves of a tooth a dentist can create a tooth surface that is smoother. There are no longer any locations on the chewing surface of the tooth that the bristles of a toothbrush can't access and clean. Since dental plaque can be removed more easily and effectively, there is much less of a chance that tooth decay will form.

Dental sealants act as a barrier, protecting the teeth against decay-causing bacteria. The sealants are usually applied to the chewing surfaces of the back teeth (premolars and molars) where decay occurs most often.

What are some problems associated with the new material?

Cavities, or dental caries, remains the most prevalent childhood disease and continues to take a heavy toll on children's health and well-being across certain socioeconomic, racial, and ethnic groups. From all available data it is clear that inadequate access to dental care is commonplace for children of families living in poverty despite tremendous advances in prevention.

In Oregon, dental disease continues to be a significant health problem for segments of this population. Low-income individuals have substantial amounts of disease and limited access to dental care. The 2002 Smile Survey found that more than 56% of Oregon children aged six to eight have a history of dental caries. Nearly one in four (24%) Oregon children surveyed had untreated dental decay, and children from low-income families were 2.5 times more likely to have untreated dental decay.

Serious tooth decay in children affect their fundamental well-being and sense of self. Children with unmet dental needs suffer the daily distraction of chronic toothaches, the acute and searing pain of dental abscesses, disfigured smile, dysfunctional speech, and difficulty eating. For every one hundred school children, 5.7 days of school, on average, are lost due to dental disease. In Oregon, that average translates to nearly 52,000 missed school days because of dental problems in 2002.

Children with dental decay who lack access to dental care are often not brought to seek care until decay is severe. More often than not, this results in very expensive, invasive, and drastic measures to address the problem, and usually involves a visit to the Emergency Room.

Clearly, dental caries are well worth preventing.

Although dental sealants are relatively inexpensive and are known to be an efficient means of preventing caries, they are underused in Oregon. In 2002, only 31% of all second-grade respondents had sealants. Among third-graders eligible for free or reduced lunch at schools, only 42% received sealants. Among non-white and/or Hispanic children, only 45% received sealants.

Schools have proven to serve as an innovative access point for children to receive sealants. In schools, children are not removed from the comfort of a familiar environment, and are less anxious and fearful of receiving a dental procedure, albeit a painless one. More importantly, all children (for whom parents or guardians have consented) receive a screening, and every child needing sealants may receive them. Children are not stigmatized by being singled out during the screening and sealing process.

What was originally used before teeth Sealants were invented?

In the past when a pin head size cavity was found dentists were taught to place a large pea sized lump of Mercury/silver in an oversized preparation. In order to do that, they drilled away about 1/3 of the middle of the tooth. This excess drilling weakens the tooth 75% and often leads to broken and dead teeth (root canals and crowns) later in life.

What are the long-term effects of etching the teeth in preparation for sealant application?

There are no long term effects of etching the teeth before sealant application. The etchant is a strong acid that dissolves the matrix material between the enamel rods that make up the tooth. It is rinsed off within seconds and leaves the tooth with a frosty appearance when dried. The nature of a resin dental sealant is that it requires a mechanical bond with the tooth, this mechanical bond is achieved between the sealant material and the enamel rods. In the case the tooth was "over etched" that is to say the sealant material is not covering the entire etched surface of the tooth, the minerals in the saliva, and topical fluoride rebuild that area of the tooth to make it as sound as it was before the procedure.

What is the history of dental sealants?

I think you mean sealants to prevent cavities right? When I was about 13 my dentist put them on a few of my back teeth (the deeper ones which he thought were prone to cavities). I am 27 now and have a cavity in most back teeth except for the ones that have the sealants on - would highly recommend for a child - not expensive and they have lasted forever. Dental sealants have been in common use for over 30 years, and they have been improved over the years. It is known that the most likely place for a child to get a cavity is in the small pits and grooves in their back teeth. That is because these small pits and grooves are extremely difficult and sometimes impossible to keep clean. A dental sealant is a plastic coating that fills in the pits and grooves before a cavity occurs without removing any tooth structure as is done when a traditional filling is placed.While not 100% effective in preventing cavities, sealants can significantly reduce the risk of getting cavities on the back teeth, especially if the child visits their dentist frequently (twice a year) to have worn out or missing sealants replaced.A sealant must be placed before a cavity appears in the tooth. Once a cavity is diagnosed by the dentist, a traditional filling must be placed.

Can dental sealant cause a reaction?

I have never seen one after placing hundreds of them over the past 30 years, nor have I read anything in the research or performance evaluation literature regarding that type of response. It is possible, however, to experience a slight, temporary chemical burn from the etching gel used to prep the tooth surface for the sealant, or an allergic reaction to the operator's latex gloves. I would advise the practitioner of your experience so it can be examined and noted in your chart.
