A dental sealant is a thin layer of resin that is applied in the pits and fissures (in the developmental grooves) of molars and premolars. These deep grooves can be difficult to clean with a toothbrush – especially when the toothbrush is in the hands of a child. With a source of food present, bacteria can easily hide in pits and fissures, produce acids and cause decay. Once decay is established, it must be restored by removing tooth structure and placing a restoration.
A sealant effectively seals out these bacteria and prevents decay from starting in the first place.
How are sealants applied?
Step 1: check for decay, followed by pumice (a simple cleaning)
Step 2: etch and rinse (roughen the tooth surface)
Step 3: apply a thin layer of sealant & set with light, check bite
Your child’s teeth need to last a lifetime.
Sealants are one of the easiest, most sensible, economical and preventive ways of preserving healthy teeth in young children.
Sealants usually last for years, often into adulthood and closely resemble natural tooth colour.
If you are considering sealants for your child, our dentists at Limebank Dental Centre would be pleased to share their experience with you.
