Your comprehensive FAQ guide in plain, easy-to-understand language
In this guide, we’ll answer the most commonly asked questions about fissure sealants in a clear, friendly format. Whether you’re a parent, a teen, or an adult thinking about preventive dental care, this FAQ-style article will help you understand everything you need to know.
❓ What Are Fissure Sealants?
Fissure sealants are thin, plastic-like coatings that cover the deep grooves (called fissures) on the chewing surfaces of your back teeth. These grooves can trap food, bacteria, and plaque, which may lead to cavities over time.
Sealants act like a protective shield, sealing off those tricky areas and making them smoother and easier to clean.
👶 At What Age Should Children Get Fissure Sealants?
Dentists usually recommend applying sealants to permanent molars as soon as they come through. The first permanent molars often appear around age 6, and the second set arrives around age 12.
Applying sealants as early as possible helps protect teeth during the years when kids are most prone to decay.
🛡️ How Do Fissure Sealants Help Prevent Tooth Decay?
Tooth decay happens when bacteria feed on leftover food and sugars, producing acid that damages enamel. The grooves in molars are often deep and hard to clean with a toothbrush, making them perfect hiding spots for bacteria.
Sealants cover these grooves, block out food and germs, and make the surface of the tooth smoother. That means fewer places for bacteria to hide and a much lower chance of cavities forming.
⚙️ What Happens During the Sealant Application Process?
Applying fissure sealants is fast and completely painless. There are no drills, no injections, and no need for numbing. Here’s how the process works:
-
Cleaning the Tooth – The dentist or hygienist starts by cleaning the tooth thoroughly to remove any plaque or food.
-
Preparing the Surface – A mild acid is applied to the tooth for a few seconds. This helps the sealant stick.
-
Rinsing and Drying – The tooth is rinsed and dried carefully.
-
Applying the Sealant – The liquid sealant is painted onto the tooth’s surface.
-
Hardening – A special curing light is used to quickly harden the sealant.
The entire procedure takes just a few minutes per tooth.
⏳ How Long Do Dental Sealants Last?
Sealants can last for several years, often up to 5 to 10 years with good care. However, they should be checked during routine dental visits to make sure they’re still intact and doing their job.
If they wear down, chip, or fall out, your dentist can easily reapply them.
👨👩👧 Are Fissure Sealants Just for Kids?
No, sealants are not just for kids. Although they’re most commonly applied to children’s teeth, teenagers and adults can benefit too—especially those who:
-
Have deep grooves in their molars
-
Have a history of tooth decay
-
Have difficulty brushing properly
Your dentist can advise if sealants are right for you or your older child.
💰 How Much Do Fissure Sealants Cost?
Sealant costs vary depending on where you live and the dental clinic you visit. On average, you might expect to pay between $30 and $60 per tooth.
For children and teens, many private health funds or government dental programs may cover the cost. Always check with your provider or dental clinic for accurate pricing and rebates.
🧪 What Are Sealants Made From?
Most dental sealants are made from a durable, tooth-colored resin material that bonds well to enamel. Some newer sealants also release fluoride, offering extra protection against decay.
They are safe, biocompatible, and designed to handle daily wear and tear from chewing.
🧼 How Do You Care for Teeth With Sealants?
Looking after teeth with sealants is easy—and just like caring for your regular teeth.
-
Brush twice a day using fluoride toothpaste
-
Floss daily to remove plaque between the teeth
-
Avoid biting on hard objects (like ice or pens)
-
Visit your dentist every 6 months for check-ups and cleaning
Good hygiene and regular check-ups will help your sealants last longer.
👦 Are Fissure Sealants Safe for Children?
Absolutely. Fissure sealants are considered very safe for children. They’ve been used for decades and are endorsed by dental associations around the world as a reliable way to prevent cavities in young teeth.
The materials used are non-toxic and well tolerated by the body. The procedure itself is completely painless and non-invasive.
🔍 Can Sealants Be Applied to Teeth With Small Cavities?
Ideally, sealants should be applied to teeth without any decay. But in some cases, if the cavity is in its very early stages (called incipient decay), a dentist may still apply a sealant to stop it from getting worse.
Your dentist will assess whether the tooth needs treatment before sealing.
🔄 Can Fissure Sealants Be Replaced?
Yes. If a sealant wears out or breaks, your dentist can easily reapply it during a routine visit.
Replacing a sealant is just as simple as the original application and takes only a few minutes per tooth. Regular check-ups help make sure your sealants are still effective.
🧬 Do Fissure Sealants Contain BPA?
Some sealants may contain trace amounts of BPA (bisphenol A), a compound found in many plastics. However, the levels in dental sealants are extremely low—much lower than everyday exposure from things like food packaging and plastic bottles.
Health authorities consider this minimal exposure safe. If you’re concerned, ask your dentist about BPA-free sealant options, which are widely available.
📋 Will My Health Insurance Fund Cover the Cost of Sealants?
Many dental insurance plans and the Medicare Child Dental Benefit Scheme include coverage for fissure sealants, especially for children and teens.
Coverage for adults may be more limited, but it depends on your individual policy. It’s always a good idea to check with your health fund or dental provider before treatment.
🏥 Where Can I Get Fissure Sealants Applied?
You can get fissure sealants applied at most general dental practices. The treatment is typically performed by a dentist or dental hygienist and is often part of a preventive dental care plan for children.
If you’re unsure whether you or your child need sealants, just book a regular check-up and ask your dentist to assess your molars.
✅ Final Thoughts: Are Fissure Sealants Worth It?
Yes, fissure sealants are an excellent preventive tool in modern dentistry. They’re safe, affordable, and highly effective at reducing the risk of tooth decay in children and adults alike.
Here’s why sealants are worth considering:
-
They protect hard-to-clean areas of your back teeth
