Maintaining good oral health is essential for a beautiful and confident smile. One of the preventive measures that dentists recommend to safeguard your teeth against decay is the application of fissure sealants.


These thin, protective coatings provide an extra layer of defense for vulnerable areas of your teeth, minimizing the risk of cavities and preserving your dental health.


In this blog, we will delve into the world of fissure sealants, understanding what they are, how they work, and why they are a valuable addition to your dental care routine.

What are Fissure Sealants?

Fissure sealants are a type of dental treatment designed to protect the chewing surfaces of your back teeth, specifically the molars and premolars. These areas often have deep grooves and fissures that can trap food particles and bacteria, making them prone to decay.


Fissure sealants are typically made of a plastic-like material, which is applied to the occlusal (biting) surfaces of the teeth. Once hardened, the sealant creates a smooth, thin, and protective barrier that seals off the fissures, preventing decay-causing bacteria from settling in those vulnerable areas.

The Fissure Sealant Procedure

The application of fissure sealants is a straightforward and painless process, usually performed by a dentist or dental hygienist. The steps involved in the fissure sealant procedure are as follows:


  • Cleaning the Teeth: Before applying the sealant, the dentist will thoroughly clean and dry the teeth to ensure proper adhesion.
  • Acid Etching: The dentist will apply a mild acidic solution to the chewing surfaces of the teeth. This solution creates a rough surface, making it easier for the sealant to bond securely to the tooth.
  • Sealant Application: The dentist will carefully apply the liquid sealant material to the prepared tooth surfaces. The sealant material flows into the deep grooves and fissures, effectively sealing them off from external factors.
  • Curing the Sealant: To harden the sealant, a special curing light is used. The light activates the sealant material, transforming it into a durable and long-lasting protective layer.
  • Polishing: After the sealant has hardened, the dentist will check the bite and make any necessary adjustments. The sealed teeth are then polished to ensure a smooth surface.

The Benefits of Fissure Sealants

Here are some of the benefits of fissure sealants:


  • Prevention of Tooth Decay: Fissure sealants act as a physical barrier, preventing food particles, plaque, and bacteria from accumulating in the deep grooves and fissures of your molars and premolars. By sealing off these vulnerable areas, the risk of cavities is significantly reduced.
  • Non-Invasive and Painless: The process of applying fissure sealants is entirely non-invasive and painless. There is no need for drilling or anesthesia, making it an ideal option for both children and adults.
  • Cost-Effective Prevention: Fissure sealants are an affordable preventive measure compared to treating cavities and more extensive dental procedures. Investing in sealants can save you money in the long run by minimizing the need for restorative treatments.
  • Long-Lasting Protection: When properly maintained, fissure sealants can last for several years, providing ongoing protection for your teeth during their most vulnerable stage.
  • Easy Maintenance: Fissure sealants require no special care. Regular dental check-ups will allow the dentist to monitor the condition of the sealants and reapply them if necessary.


Fissure sealants are an invaluable tool in preventive dentistry, offering a simple yet effective way to protect your teeth from decay. By sealing off the deep grooves and fissures, these thin coatings act as a barrier, preventing harmful bacteria and food particles from wreaking havoc on your molars and premolars.


The painless and non-invasive procedure makes fissure sealants suitable for patients of all ages, particularly children whose developing teeth are especially susceptible to cavities.


If you want to safeguard your smile and maintain excellent oral health, consider discussing fissure sealants with your dentist.


Together, you can create a comprehensive preventive dental plan that includes these protective coatings, ensuring your teeth stay strong, healthy, and cavity-free for years to come.


Remember, prevention is the key to a radiant and confident smile, and fissure sealants are here to shield your teeth from the risks of decay. Visit Kangaroo Point Dental today!

Easy to book online, instant confirmation and great follow up from reception. ❤️ Dr Zen didn’t race through a consult like a checklist, that was my first impression! I usually feel like there’s a ‘procedure’ at the dentist and the time limit. He took excellent photos (if you can call tooth decay 🦷 photos excellent) to show and carefully explain what my treatment plan should look like and most importantly why!!
