What are Dental Sealants?
A dental sealant (also known as a fissure sealant) is a thin, protective coating applied to the chewing surfaces of the back teeth (molars and premolars). These areas often have deep grooves where food particles get trapped, making them highly susceptible to decay. The sealant acts as a physical barrier, smoothing out these surfaces so plaque cannot settle.
The Benefits of Dental Sealants
Tooth Decay and Cavities
Our protective coatings help prevent food debris and harmful bacteria from settling into vulnerable tooth grooves.
Vulnerable Molars and Premolars
Sealants protect high-risk back teeth that are often very difficult to clean thoroughly with standard daily brushing.
Deep Pits and Fissures
Applying a sealant smooths pronounced dental depressions, lowering the likelihood of plaque accumulation on biting surfaces.
Early Enamel Weakness
Where early enamel softening is present, sealants act as a preventive measure to preserve natural tooth structure.
Patients at Higher Risk of Cavities
Individuals with orthodontic appliances or high sugar intake benefit greatly from the added protection these sealants provide.
Preventive Care for Children
Applying sealants when permanent molars erupt offers vital protection during years when children are most decay-prone.
Preventive Treatment for Adults
Adults with healthy, unrestored back teeth receive an essential safeguard alongside their routine dental hygiene and examinations.
Additional Protection for Special Care Needs
Sealants provide an important extra layer of defence for patients who find effective brushing and flossing challenging.
When Should Children Get Sealants?
We recommend considering sealants as soon as your child’s permanent back teeth erupt, typically around age six. Applying protection early prevents bacteria from building up in deep crevices.
Typical Development Timeline:
Age 6–7
First permanent molars erupt; an ideal time to seal all four adult molars.
Age 10–12
First and second premolars replace baby molars and benefit from protection.
Age 12–13
Second permanent molars emerge; these are high-risk areas for decay.
The Procedure: Step-by-Step
The process is non-invasive, designed to minimise discomfort, and typically takes only a few minutes to complete per tooth.
Clinical Assessment
We carefully examine each tooth to ensure they are healthy and entirely free from active dental decay.
Cleaning
The tooth surface is thoroughly cleaned and dried to prepare it for the professional sealant placement process.
Preparation
A gentle conditioning solution is applied to the enamel to help the sealant bond securely and effectively.
Application
The liquid dental sealant is painted onto the grooves, flowing into every fissure for a seamless finish.
Curing
A specialised light hardens the material quickly, creating a durable protective shield over your natural tooth enamel.
While highly effective, sealants may occasionally wear or chip over time and require reapplication during routine visits.

Dental Sealants FAQs
Dental sealants are designed to be aesthetically discreet, usually appearing clear, white, or tooth-coloured to blend seamlessly with your natural enamel. Once the resin is applied, it becomes virtually unnoticeable when you smile or speak. Most patients cannot see or feel the coating after placement, as it sits smoothly within the tooth’s natural contours.
