Ask the Dentist: Is dental sealant necessary for my child’s teeth? Is it safe?

Dental sealants help to protect teeth which have grooved and pitted surfaces. These tiny grooves and pits are mostly found on chewing surfaces of the back teeth and can be difficult to clean. This results in food and bacteria building up in these crevices, increasing the risk of tooth decay.

Teeth that will benefit most from sealants include: 

• First permanent molars: These usually erupt between 6 to 7 years old
• Second permanent molars: These usually erupt between 11 to 13 years old
• Baby or permanent teeth with dental defects 

Other teeth may also benefit from the protection of dental sealants when children are at higher risk of developing dental problems. These include the premolars and baby molars. 

As every child is unique, you are recommended to bring your child to see a paedodontist or child dentist to check which teeth would benefit from dental sealants. 

Dental sealants are made of clear or shaded plastic. The procedure is safe and commonly performed. 

The application of dental sealant is also fast and comfortable for your child. After the tooth is thoroughly cleaned, the sealant is flowed into the grooves and crevices of the tooth and hardened with a special light. After the appointment, your child will be able to eat and drink as per usual. 

When properly cared for, dental sealants can last many years. It is important to note that a dental sealant is not a substitute for routine dental care. Hence it is important to continue brushing, flossing and making regular dental visits to keep your child cavity free.
