Dental Sealants: Preventing Cavities Before They Start

In the heart of Edmonton, a silent revolution is underway in the world of dental health. Dental sealants, a remarkable yet underutilized tool, are taking centre stage in the battle against tooth decay. This article delves into the transformative power of dental sealants, unveiling their role as preventative champions in maintaining oral health in the City of Champions.

What are Dental Sealants?

Dental sealants are thin, plastic coatings painted on the chewing surfaces of the back teeth – primarily the molars and premolars. They’re designed to prevent tooth decay by shielding against bacteria and plaque. Sealants are particularly beneficial for children and teenagers, but adults without decay or fillings in their molars can also reap their benefits.

The Rising Concern of Cavities in Edmonton

Edmonton, like many cities, faces challenges in oral health, with cavities being a primary concern. The consumption of sugary foods and beverages, coupled with inadequate dental care practices, contributes to this issue. Dental sealants offer a proactive solution by protecting the teeth before decay begins.

The Process of Applying Dental Sealants

The application of dental sealants is straightforward and painless, typically completed in one dental visit. The process involves cleaning and drying the tooth, followed by the application of an acidic gel. This gel roughens the tooth surface for a stronger sealant bond. After a few seconds, the dentist rinses off the gel, dries the tooth, and then applies the sealant onto the tooth’s grooves. A special light is used to harden the sealant.

Suitability and Longevity

Dental sealants are most effective when applied to children and teenagers between the ages of 6 and 14, as these are the cavity-prone years. However, they’re also beneficial for adults at risk of decay. Sealants can protect teeth from decay for up to 10 years, but they need regular check-ups for chipping or wearing. Learn more about oral surgery in Edmonton.

Benefits of Dental Sealants

The benefits of dental sealants are significant, especially when considering their role in preventive oral healthcare. Here’s a detailed explanation of these benefits:

  1. Prevention of Tooth Decay: The primary benefit of dental sealants is their ability to prevent cavities. Sealants are applied to the chewing surfaces of back teeth, where most cavities in children and teens tend to develop. These surfaces are prone to decay due to the presence of grooves and depressions (fissures) which can trap food particles and bacteria. The sealant forms a protective shield over the enamel of each tooth, blocking out bacteria, food, and plaque, thereby reducing the risk of cavities.
  2. Cost-Effective in the Long Run: The cost of applying dental sealants is relatively low compared to the cost of treating cavities and tooth decay. By preventing cavities, sealants can save individuals and families significant amounts of money over time. The expense of filling a cavity, root canal treatment, or even tooth extraction due to decay is substantially higher than the preventive measure of applying sealants.
  3. Non-Invasive and Painless Procedure: The process of applying dental sealants is simple, quick, and pain-free. It does not require any drilling or removal of tooth structure, making it an ideal preventive measure for children and adults who may have dental anxiety. This simplicity encourages more people to opt for this preventive treatment.
  4. Long-Lasting Protection: Once applied, dental sealants can protect teeth from decay for many years. They are durable and can withstand the normal forces of chewing. Regular dental check-ups are important to monitor the condition of the sealants and reapply them if necessary, but they generally provide long-term protection.
  5. Promotes Better Overall Oral Health: By preventing cavities and tooth decay, sealants help maintain better overall oral health. This is particularly important for children and adolescents, whose oral hygiene practices may not be as thorough as needed to prevent cavities. Maintaining healthy teeth and gums is crucial for overall health, as poor oral health has been linked to various other health issues.
  6. Beneficial for Children and Adults: While dental sealants are particularly beneficial for children and teenagers – who are most susceptible to cavities – they can also be applied to adults at risk of decay, especially those who have deep grooves and depressions in their molar teeth.
  7. Time-Efficient: The application of dental sealants is a relatively quick process, usually completed in one dental visit. This makes it a convenient option for busy families or individuals.

Addressing Concerns and Myths

Despite their benefits, some Edmontonians may have concerns about dental sealants, particularly regarding their safety. It’s important to note that sealants are safe and effective. They contain a very small amount of BPA, but the amount is significantly lower than what people are exposed to in daily life through other sources.

The Role of Dentists in Edmonton

Dentists in Edmonton play a pivotal role in educating the community about the benefits of dental sealants. They provide personalized advice on whether sealants are a suitable option based on individual dental histories and needs.


In conclusion, dental sealants stand as an effective, safe, and cost-efficient method to prevent cavities and promote oral health in Edmonton. As more individuals become aware of and opt for this preventive measure, we move closer to a future where tooth decay is no longer a common concern. Embracing dental sealants is a step forward in ensuring that the smiles of Edmontonians remain healthy and bright for years to come.

Edmontonians are encouraged to consult with their local dentists to learn more about dental sealants and whether they are the right choice for themselves or their family members. Remember, preventive care is the key to long-term oral health.
