Fissure Sealing Treatment
Fissure sealant treatment is a preventive dental method applied especially in children to protect the chewing surfaces of back teeth with deep grooves against decay. The fine indentations and protrusions on the upper surface of molars, called fissures, cannot always be adequately cleaned with brushing. These areas are more prone to accumulating food debris and bacterial plaque. As a result, one of the most common types of decay in children’s teeth begins exactly in these chewing grooves. The application of a fissure sealant aims to significantly reduce the likelihood of decay by covering these risky areas with a fluid protective material.
This treatment is not a repair performed after decay has formed; it is a preventive approach that comes into play before decay begins. One of the most valuable strategies in pediatric dentistry is to protect risky surfaces before it becomes necessary to intervene in the tooth. Because once decay starts in a tooth, a filling becomes necessary. However, the goal of a fissure sealant is to prevent the need for a filling from the very beginning. For this reason, it is a highly effective application especially on newly erupted permanent first molars and suitable primary molars.
The fissure sealant procedure is painless, usually does not require anesthesia, and is completed in a short time. Thanks to this feature, it also helps children have a positive first experience with the dentist. Permanent molars that erupt around the age of 6 may sometimes be mistaken for baby teeth by families and therefore not given enough importance. However, these teeth are permanent and will remain in the mouth for life, and they become vulnerable to decay as soon as they erupt. A fissure sealant provides strong protection during this critical period.
Of course, not every grooved tooth automatically receives a fissure sealant. The level of eruption, decay risk, oral hygiene, surface structure, and the child’s overall risk profile are all evaluated together. When applied to the right tooth at the right time, it can provide long-term protection. However, an important point is that fissure sealants are not a substitute for brushing. Regular brushing, balanced nutrition, and routine check-ups should continue as essential oral health habits.
In short, fissure sealant treatment is a practical, effective, and preventive application used to protect children’s back teeth against decay. This small intervention performed at an early stage plays an important role in reducing the need for fillings and more extensive treatments in the future. In pediatric dentistry, sometimes the best treatment is the precaution taken before any decay occurs.
What Is Fissure Sealant Treatment?
Fissure sealant treatment is a preventive dental practice that makes back teeth with deep grooves on their chewing surfaces more resistant to decay by covering these indented structures with a protective material. The word “fissure” refers to the natural grooves found especially on the upper surfaces of teeth. These areas can be anatomically narrow and deep. Toothbrush bristles may not always reach these points fully. Thus, food residues and bacteria can more easily accumulate in these regions. The fissure sealant reduces bacterial buildup and lowers the risk of decay by covering these risky surfaces with a thin barrier. This treatment is one of the most concrete examples of the preventive approach in pediatric dentistry. Because the intervention is not performed due to existing decay, but to prevent decay from occurring. In other words, a fissure sealant is not a filling. It is not a restorative procedure done due to tissue loss in the tooth, but an application aimed at protecting a still-healthy tooth that carries a risk of decay. This distinction is very important for families. Because sometimes applying material onto a tooth may be mistaken for a “filling.” However, a fissure sealant is applied to prevent a healthy tooth from decaying. The teeth most commonly treated are newly erupted permanent first molars. These teeth usually erupt around age 6 and are among the most decay-prone permanent teeth. The main reasons are their position at the back of the mouth, their deeply grooved chewing surfaces, and the fact that families may sometimes mistake them for baby teeth. In suitable children, fissure sealants can also be applied to primary molars. The decision is made based on the tooth’s surface structure and decay risk. The main features of fissure sealant treatment are:- Preventive in purpose
- Applied before decay begins
- Painless
- Usually does not require anesthesia
- Completed in a short time
- Especially effective on the chewing surfaces of molars
How Is Fissure Sealant Treatment Applied?
Fissure sealant treatment is a painless procedure that is completed in a short time and usually does not require anesthesia. Before the procedure, it is evaluated whether the tooth is suitable for a fissure sealant. Not every grooved tooth automatically receives this treatment. Factors such as whether there is active decay on the tooth surface, suspicion of an initial lesion, whether the tooth has fully erupted, and whether oral hygiene and dryness can be maintained are assessed. If necessary, radiographic evaluation may be added to the clinical examination. In the first stage, the tooth surface is cleaned. This cleaning is important to remove plaque and debris accumulated in the grooves. Then, the tooth is kept dry. Isolation is a critical factor in the success of the fissure sealant. If saliva contaminates the area during application, the material’s adhesion to the tooth may decrease. Therefore, cotton rolls, suction, and proper field control are carefully used. After preparing the tooth surface, the enamel is microscopically roughened with a special conditioning solution. This step allows the material to bond better mechanically to the tooth. Then the surface is rinsed and dried again. The fissure sealant material is carefully placed into the chewing grooves. It fills the grooves but does not create excessive height. Finally, the material is hardened using a special light device. The bite is then checked, and it is evaluated whether the child can use the tooth comfortably. Fissure sealant treatment generally follows these steps:- Evaluating the suitability of the tooth
- Surface cleaning
- Keeping the tooth dry
- Preparing the enamel surface
- Applying the fissure sealant material
- Light curing
- Checking occlusion and retention
Who Is Suitable for Fissure Sealant Treatment?
Fissure sealant treatment is especially suitable for children who have deep grooves on their chewing surfaces and are at risk of developing decay. The ideal goal is to protect risky surfaces before decay occurs. Therefore, suitability is not determined solely by whether the child currently has cavities. The anatomical structure of the tooth, eruption stage, oral hygiene, dietary habits, and overall decay risk profile are evaluated. The most suitable period is usually when permanent first molars have just erupted, around the age of 6. These teeth can easily become prone to decay because they are difficult to clean and may be overlooked. Fissure sealants may also be applied to suitable primary molars in children with high risk. Children suitable for fissure sealants include:- Those with newly erupted molars
- Those with deep and retentive grooves
- Children with high decay risk
- Those with previous decay experience
- Those whose oral hygiene is still developing
- Those with frequent sugar consumption
- Those with a family history of high decay rates
