Dental Sealants: What Are They? Risks, Costs, and Benefits

6 min read

When you’re searching for ways to protect your teeth, dental sealants often come up as a great option. But what exactly are dental sealants? Are they worth it? And what should you know about their costs, risks, and benefits? This guide answers all your questions and more, helping you make an informed decision.

What Are Dental Sealants and How Do They Work?

Dental sealants are thin, plastic coatings that dentists apply to the chewing surfaces of your back teeth (molars and premolars). These teeth are often more vulnerable to cavities because they have deep grooves and fissures that are hard to clean, even with regular brushing.

How Do Sealants Work?

  • The sealant is painted onto the chewing surfaces of your teeth.
  • It bonds to the tooth surface, creating a smooth, protective layer.
  • This layer acts as a barrier to prevent food particles and bacteria from getting stuck in the grooves.

Composition and Application:

  • Dental sealants are made of plastic resins that bond to the enamel.
  • The material used is either bisphenol-A glycidyl methacrylate (Bis-GMA) or Resilon, both of which provide a durable, long-lasting protective coating.

Mechanism of Action: When the sealant is applied, it undergoes a process known as etching. This involves a mild acid being used to roughen the surface of the tooth so that the sealant can bond better. This bonding is achieved by creating tiny micro-retentions on the tooth surface, allowing the sealant to “grab” onto the enamel more securely, preventing it from peeling off.

Benefits of Dental Sealants: Why You Should Consider Them

Now that you understand what dental sealants are, let’s dive into why they are so beneficial. If you’re looking for a way to protect your teeth and save money on dental procedures down the line, sealants are a great option. Here’s why:

  • Prevents Cavities: Sealants can reduce the risk of cavities by up to 80%, especially in deep grooves where decay tends to form.
  • Cost-Effective: They are much cheaper than fillings, crowns, or root canals. For example, the cost of sealants ranges from $30 to $60 per tooth, while a filling can cost hundreds of dollars.
  • Long-Lasting Protection: Sealants can last 5 to 10 years, giving you peace of mind for the long term.
  • Reduces Sensitivity: By sealing grooves and fissures, sealants can also help reduce tooth sensitivity when eating hot or cold foods.
  • Minimal Maintenance: Once applied, dental sealants require little to no maintenance and don’t interfere with your daily oral care routine.

Risks of Dental Sealants: Are There Any Downsides?

While dental sealants are generally safe, it’s important to know about the potential risks:

  1. Allergic Reactions:
    • Example: Some people might be allergic to Bis-GMA, a common component of dental sealants. This could lead to symptoms like redness or swelling around the treated tooth.
  2. Incomplete Coverage:
    • If the sealant doesn’t cover the entire tooth or starts to wear off, bacteria can still get trapped in the grooves, increasing the risk of cavities.
  3. Potential Toxicity:
    • Example: Sealants made with Bisphenol-A (BPA) have raised concerns, though the amounts used are minimal and considered safe by most health authorities. However, for those cautious about BPA, BPA-free sealants are available.
  4. Chipping or Cracking:
    • Example: Sealants can wear down over time, especially if you chew on hard foods like ice or candy. If a sealant cracks, your tooth may be exposed to the risk of decay.

Costs of Dental Sealants in the USA: Is It Worth It?

Understanding the cost of dental sealants is essential, especially when considering them as an investment in your long-term oral health.

  1. Price Range:
    • Dental sealants typically cost between $30 and $60 per tooth. This can vary depending on the dentist and your location.
  2. Regional Variations:
    • Example: In larger cities or metropolitan areas, the cost can be higher due to overhead costs. However, smaller towns might offer lower prices for the same service.
  3. Insurance Coverage:
    • Many dental insurance plans cover the cost of sealants, especially for children. Some plans may even cover sealants for adults if you have high cavity risk.
  4. Cost Savings in the Long Run:
    • Sealants can help you avoid more expensive dental procedures, like fillings, root canals, and crowns, which can cost $150 to $2,000 or more. By preventing cavities in the first place, sealants pay for themselves over time.

Who is a Good Candidate for Dental Sealants?

If you’re wondering whether dental sealants are right for you or your child, here’s what to consider:

  • Children and Teens:
    • Sealants are highly recommended for children between 6 and 12 years old when their molars first come in. This is the ideal time to apply sealants as it helps protect teeth from cavities early on.
  • Adults with Deep Grooves:
    • If you have deep fissures in your molars, you might benefit from sealants even as an adult. Sealants can protect against cavities that are harder to reach with brushing alone.
  • Individuals with Poor Oral Hygiene:
    • If brushing and flossing are difficult for you, dental sealants offer an added layer of protection against decay.

Dental Sealants vs. Other Preventative Measures: What’s the Best Choice?

While dental sealants are excellent for preventing cavities, they are just one tool in your oral health toolkit. Here’s how they compare with other options:

  1. Fluoride Treatments:
    • Fluoride helps strengthen enamel but doesn’t provide the same direct protection from food and bacteria as sealants do. Fluoride is great for overall enamel health, while sealants protect specific areas.
  2. Dietary Changes:
    • Reducing sugar intake is critical for oral health, but sealants can act as an additional barrier against decay, especially in hard-to-reach grooves.
  3. Regular Brushing and Flossing:
    • While these practices are vital, sealants protect areas where brushing may not be enough, making them a helpful addition to your routine.

Longevity and Maintenance of Dental Sealants: How to Keep Them Effective

Dental sealants are designed to be long-lasting, but certain factors can influence their lifespan:

  1. Regular Checkups:
    • Visit your dentist regularly to ensure that the sealants are still intact and providing protection.
  2. Avoid Hard Foods:
    • To keep your sealants from chipping, avoid chewing on hard foods like ice or sticky candies.
  3. Signs of Wear:
    • If you notice any chips or wear, your dentist can reapply or replace the sealant to keep it effective.

Conclusion:

Dental sealants are a simple, cost-effective way to prevent cavities and protect your teeth for years to come. They’re especially beneficial for children and those with deep grooves in their molars, but adults can benefit as well. If you’re considering dental sealants, talk to your dentist about whether they’re a good fit for your teeth. Ask about the materials they use and how long the sealants are likely to last.

Pro Tip: If you have questions like, “Are dental sealants right for me?” or “What’s the best time to get sealants for my child?” your dentist will be happy to guide you through your options based on your unique needs.
