Dental sealants are thin, protective coatings applied to the chewing surfaces of molars and premolars. They act as a barrier, shielding teeth from food particles and bacteria that cause cavities. Studies show sealants can prevent up to 80% of cavities within the first two years and continue protecting against 50% of cavities for up to four years. They are especially recommended for children aged 6 to 14, though adults at risk of tooth decay can benefit too.
Key Points:
- What they do: Sealants fill grooves on teeth, making them easier to clean and preventing bacteria from settling.
- Who needs them: Ideal for children, teenagers, and adults with deep grooves or a history of cavities.
- Process: Quick, painless, and involves cleaning, drying, applying a bonding gel, and sealing with a hardening light.
- Benefits: Reduced risk of cavities, cost-effective prevention, and easier oral hygiene maintenance.
Sealants are a simple way to protect your teeth and avoid costly dental treatments later. Regular dental check-ups ensure they stay effective and durable over time.
How Dental Sealants Work
The Application Process
Applying dental sealants is a quick and straightforward process, taking just a few minutes per tooth. It starts with the dentist thoroughly cleaning the tooth to remove plaque and debris, ensuring the sealant adheres properly.
Once cleaned, the tooth is dried, and an acidic gel is applied to its surface. This step etches the enamel, creating a texture that helps the sealant bond securely. After about 15–20 seconds, the gel is rinsed off, and the tooth is dried again. The dentist then uses a small brush or applicator to carefully place the liquid sealant into the grooves and fissures of the tooth.
To finish, the sealant is hardened using a blue curing light. This light triggers a chemical reaction in the resin, causing it to solidify into a tough, protective coating within seconds. Some sealants don’t require light and harden on their own. Once set, the sealant forms a strong shield that can handle everyday chewing forces.
How Sealants Stop Cavities
Sealants protect teeth by forming a physical barrier that blocks bacteria from reaching vulnerable areas. The deep grooves and fissures on molars are particularly tricky to clean with a toothbrush, making them hotspots for plaque and bacteria.
Bacteria like Streptococcus mutans thrive in these hard-to-reach spots, feeding on trapped food particles and sugars. This process produces lactic acid, which weakens enamel and leads to cavities. Sealants solve this issue by filling in the grooves, creating a smooth surface where bacteria can’t hide.
The smooth surface also makes brushing more effective, as food particles and plaque slide off easily. This reduces the bacterial presence and prevents the acid production that causes tooth decay. Even if some bacteria remain on the surface, the protective layer stops them from penetrating the enamel. Some sealants even offer extra features that enhance their protective capabilities.
Extra Benefits of Some Sealants
Modern sealants go beyond just acting as a barrier. Fluoride-releasing sealants provide ongoing protection by strengthening enamel through remineralisation.
Some advanced sealants include calcium and phosphate ions, which are essential for building strong enamel. These ions help repair tiny weak spots in the enamel before they turn into cavities. By slowly releasing these minerals, the sealant creates a protective environment that actively combats bacterial acid attacks.
Glass ionomer sealants are particularly noteworthy for their bioactive properties. They not only seal the tooth but also bond chemically with the enamel. Additionally, they release beneficial ions over several months, making them ideal for children who are at a higher risk of cavities or have limited access to fluoride from sources like water or toothpaste.
Benefits and Results of Dental Sealants
Main Benefits of Dental Sealants
Dental sealants act like a protective shield for your teeth, covering the chewing surfaces to block plaque buildup and prevent decay. This helps preserve your natural tooth structure without the need for invasive procedures. Plus, sealants are a cost-effective way to avoid expensive dental treatments in the future. Their clear or tooth-coloured appearance blends seamlessly with your teeth, making them a great choice – especially for children or anyone who feels anxious about dental visits.
Research and Statistics
The benefits of sealants are backed by solid research. Studies show that children with sealants experience fewer cavities than those who don’t have this preventive measure. School-based sealant programmes have also been linked to better oral health outcomes in participating children.
What’s even better? Sealants applied early can provide lasting benefits, reducing the likelihood of needing major dental work as the years go by.
How Long Sealants Last
Sealants are built to offer long-term protection, but their lifespan can vary depending on your oral hygiene habits and diet. While some sealants may wear down faster, others are designed to last for years, maintaining their protective role.
Regular dental check-ups are key to ensuring your sealants stay effective. If they begin to wear out, they can be reapplied quickly and easily to continue protecting your teeth from decay. This makes sealants an essential part of long-term cavity prevention.

Who Should Get Dental Sealants
Best Candidates for Dental Sealants
Dental sealants are particularly beneficial for children and teenagers, especially during the years when their first and second molars emerge. First molars typically appear between the ages of 5 and 7, while second molars make their appearance between 11 and 14 years. Applying sealants during these cavity-prone years provides an extra layer of defence against decay.
Adults, too, can benefit from sealants, especially those with deep grooves in their teeth or a history of cavities. If plaque tends to accumulate in the crevices of your teeth, sealants can offer an additional barrier of protection. For individuals at high risk of cavities, regardless of age, sealants can be a smart preventive measure. Discussing your specific needs with your dentist will help determine if sealants are the right choice for you.
Talking to Your Dentist
Your dentist plays a key role in determining whether dental sealants are suitable for you. During a professional evaluation, they will examine the grooves on your teeth, your history of cavities, and your overall oral hygiene habits. Based on this assessment, they’ll recommend the most suitable type of sealant – whether it’s a traditional resin-based sealant or a fluoride-releasing glass ionomer.
It’s a good idea to ask your dentist about how sealants fit into your broader oral health plan. Understanding the type of sealant being used and how it complements your dental care routine can help you make informed decisions.
Regular Check-ups and Care
Once sealants are applied, regular dental visits are essential to ensure they remain effective. At The Dental Lounge, comprehensive dental check-ups start at ₹500 and include an evaluation of the sealants’ condition to ensure they’re providing maximum protection.
Routine check-ups can identify any chips or wear in the sealants, allowing for timely repairs or reapplications. Your dentist may also offer guidance on brushing and flossing techniques to maintain the health of sealed teeth as part of an overall preventive care routine. Proper maintenance ensures that sealants continue to shield your teeth from cavities effectively.

FAQs
How are dental sealants different from fluoride treatments for preventing cavities?
Dental sealants and fluoride treatments both play a key role in keeping cavities at bay, but they tackle the problem differently. Sealants act as a shield, covering the grooves and pits on the surface of teeth. These areas can be tricky to clean and often trap food and bacteria. By sealing them off, sealants help prevent decay, making them particularly useful for molars and other cavity-prone teeth.
Fluoride treatments, on the other hand, work by strengthening the tooth enamel. They help remineralise the enamel, making it tougher and less likely to be damaged by acids or decay. While fluoride protects all teeth by enhancing their resistance, sealants focus on safeguarding specific vulnerable spots. Used together, they offer a well-rounded approach to cavity prevention.
Can dental sealants be applied to teeth with minor cavities or early signs of decay?
No, dental sealants are not meant for teeth that already have cavities or visible decay. Applying a sealant over a decayed tooth can trap bacteria inside, which might cause the cavity to progress further. In such cases, the decay needs to be treated by a dentist first before exploring any preventive options like sealants.
If you’re uncertain whether dental sealants are right for your teeth, consult a dentist. They can evaluate your oral health and recommend the best course of action to keep your teeth in good condition.
How should dental sealants be maintained, and how often should a dentist check them?
Dental sealants are incredibly easy to maintain, but they still need to be checked during your routine dental visits – ideally every six months. These check-ups give your dentist a chance to ensure the sealants are still in place and doing their job of protecting your teeth from cavities.
While sealants can last anywhere from 5 to 10 years, they aren’t immune to wear and tear. Over time, they might chip or wear down. Regular visits to your dentist help catch these issues early, ensuring your sealants continue to shield your teeth effectively. Sticking to your twice-a-year dental appointments is the best way to keep them working as they should.
