What Happens If You Put Dental Sealants Over A Cavity?

Dental sealants are a crucial tool in preventive dentistry, providing a protective barrier against tooth decay. Applied mainly to the chewing surfaces of molars and premolars, they prevent cavities by sealing out food particles and bacteria. This blog explores the importance of dental sealants, the implications of applying them over cavities, and the steps dentists take to ensure proper application. Getting the know-how of these facets helps in making informed decisions for optimal oral health.

Understanding Dental Sealants

These are plastic thin coatings applied to the chewing surfaces of the back teeth. They work by sealing the grooves and pits where food particles and bacteria commonly accumulate, thereby preventing tooth decay. The materials commonly used for sealants include resin-based compounds, which harden quickly to form a protective layer. The typical application process involves cleaning the teeth, applying an acid solution to roughen the surface, rinsing and drying the teeth, and finally, putting the sealant over the tooth enamel where it bonds and hardens. Sealants are especially efficient for children and teenagers who may have difficulty upholding proper oral hygiene.

What Are Cavities?

Cavities, or dental caries, are permanently damaged or ruined areas in the hard surface of your teeth that develop into tiny openings or incisions. They are caused by a blend or combination of factors, including bacteria in the mouth, eating snacking frequently, consuming sugary drinks, and not cleaning your teeth well. Tooth decay progresses through several stages, starting from the initial demineralization of the enamel, moving to the dentin, and eventually reaching the pulp of the tooth if untreated. Early diagnosis and treatment are very important to prevent the progression of cavities and maintain good oral health.

Can Dental Sealants Be Applied Over Cavities?

No, dental sealants should not be applied over cavities. Sealants are meant to be used as a preventive measure to protect the teeth from developing cavities by closing or sealing off the grooves and pits where bacteria can accumulate. If a cavity is present and a dental coating is applied over it, it can trap bacteria and decay underneath, leading to further progression of the cavity and potential complications. It’s essential to address cavities with appropriate dental treatments, such as fillings, before considering sealant application.

Consequences of Applying Sealants Over a Cavity

Applying dental sealants over a cavity can have several negative consequences, such as:

• Compromised sealant effectiveness: Sealants are most effective when applied to clean, healthy tooth surfaces. Applying them over cavities undermines their effectiveness, as they may not adhere properly to the compromised tooth structure, leading to premature wear or failure of the sealant.
• Risk of infection: Cavities are caused by a bacterial infection in the tooth enamel. When sealants are applied over cavities, there’s a risk that the bacteria trapped underneath the sealant can continue to thrive and cause further infection, potentially leading to complications such as dental abscesses or gum disease.
• Need for additional treatment: If tooth sealants are inadvertently applied over cavities, it may necessitate additional dental treatment to address the underlying decay. This could involve removing the sealant, cleaning the cavity, and applying a filling or other restorative treatment to repair the tooth and prevent further damage.
• Discomfort and sensitivity: Sealants applied over cavities may exacerbate symptoms such as tooth sensitivity or discomfort as the underlying decay continues to progress unchecked. This can impact the individual’s quality of life and may necessitate intervention to alleviate symptoms and address the underlying issue.

How Do Dentists Determine Cavity Presence Before Sealant Application?

Dentists employ various techniques and diagnostic tools to assess the presence of cavities before applying dental sealants near you:

• Visual examination: Dentists visually inspect the teeth for indications of decay, such as discoloration, visible holes or pits, and changes in tooth texture.
• Dental probes: Dental probes are used to gently explore the surfaces of the teeth, checking for soft spots or areas of weakness that may indicate the presence of cavities.
• X-rays: X-rays, also known as dental radiographs, offer intricate images of the teeth and underlying structures. Dentists use these images to detect cavities between teeth or beneath the enamel surface.
• Laser fluorescence devices: Some dentists utilize laser fluorescence devices to detect early signs of tooth decay. These devices emit light onto the tooth surface and measure the fluorescence emitted by decayed areas.
• Transillumination: Transillumination involves shining a bright light through the tooth to detect cavities or cracks that may not be visible during a visual examination.
• Magnification tools: Dentists may use magnification tools such as loupes or dental microscopes to examine the teeth more closely, enabling them to detect subtle signs of decay.
• Previous dental records: Dentists may review a patient’s dental history and previous X-rays to track changes in tooth structure over time and identify areas of concern.

Alternatives to Sealants for Cavities

There are several alternatives to dental sealants for treating cavities, each with its advantages and considerations:

• Fillings: Dental fillings are one of the most common treatments for cavities. During this procedure, the dentist eliminates the decayed or ruined part of the tooth and fills the cavity with a dental material, including composite resin, amalgam, or glass ionomer cement. Fillings restore the tooth’s structure and function while preventing further decay.
• Preventive measures: Besides treating cavities, preventive measures can help minimize the risk of new cavities forming. These measures may include upholding good oral hygiene habits, like brushing and flossing every day, using fluoride toothpaste and mouthwash, and limiting sugary foods and drinks.
• Regular dental cleanings: Professional dental cleanings performed by a dental hygienist eliminate plaque and tartar buildup from the teeth, lessening the risk of cavities and gum disease. Regular cleanings also allow the dentist to monitor the teeth for signs of decay and provide early intervention when necessary.
• Dental crowns: In cases where a cavity is too large to be treated with a filling, a dental crown may be recommended. Crowns are custom-made restorations that cover the complete tooth, providing protection and support while restoring its appearance and function.
• Root canal therapy: If a cavity has progressed to the interior layer of the tooth, known as the pulp, root canal therapy might be needed to save the tooth. While this procedure is ongoing, the infected tooth pulp is eliminated, following which the root canal is cleaned, filled, and closed or sealed to prevent further infection.

Proper Use of Dental Sealants

Dental sealants are most effective when used appropriately. Suitable candidates for sealants are children and teenagers at a higher risk for cavities, particularly those who have just had their permanent molars come in. Adults without existing decay or fillings in their molars can also benefit. The maintenance of sealants involves regular dental check-ups to ensure they remain intact and effective. While sealants can last several years, they may need to be reapplied or repaired over time. Dental sealants in Uncasville, CT, play a crucial role in preventive dental care by providing an additional layer of protection against decay.

Conclusion

Dental sealants are effective in preventing cavities and promoting oral health. However, applying sealants over existing cavities can trap bacteria and worsen decay, underscoring the importance of thorough dental check-ups. Dentists use various diagnostic tools to ensure sealants are applied appropriately. Follow professional dental advice and maintain regular dental visits for the best results.
