Dental Sealants for Kids in Christiansburg, VA

A sealant is a thin protective coating that is painted onto the chewing surfaces of the back teeth, the molars and premolars. These teeth have natural pits and grooves that are often narrower than a single toothbrush bristle, so plaque collects there even in children who brush well. Once the sealant hardens, it forms a smooth shield over the grooves.

According to the Centers for Disease Control and Prevention (CDC), sealants protect against about 80% of cavities in the back teeth for two years and continue to protect against about half of cavities for up to four years. Our guide on how dental sealants work explains the science in more detail.

Sealants are usually placed soon after the permanent molars come in, before decay has a chance to start:

• First permanent molars: usually around age 6.
• Second permanent molars: usually around age 11 to 13.
• Premolars and baby molars: sometimes sealed when they have deep grooves or a child has a higher risk of cavities.

At each checkup, the dentist looks at which teeth have come in and whether sealants would help. Sealants work alongside brushing, flossing and fluoride varnish treatment, not in place of them.

Placing a sealant is one of the simplest visits your child will have:

• Cleaning: the tooth is polished so the surface is free of plaque.
• Preparing: a mild solution is applied to help the sealant bond, then rinsed off and the tooth is dried.
• Painting: the sealant is brushed into the grooves.
• Hardening: a small blue light sets the sealant in a few seconds.

There are no shots and no drilling, and your child can eat and drink normally right after the visit. Many families schedule sealants at the same visit as a routine exam and cleaning.

Sealants can last for several years. They are checked at every visit, and if one wears down or chips, it can be repaired or reapplied in a few minutes. Sealants are a common preventive service, and many dental plans cover them for children's permanent molars. Our article on sealant costs and insurance walks through coverage questions, and our team is happy to check your benefits before the visit.

Sealants protect the chewing surfaces, but cavities can also start between the teeth and along the gumline, where sealants do not reach. That is why we pair sealants with daily brushing using fluoride toothpaste, flossing once teeth touch, fluoride varnish at checkups and smart snacking habits. Limiting sticky snacks and sugary drinks between meals also helps, because every sip or snack starts a new acid attack on the teeth. At each visit we check sealants for wear and look for early signs of decay elsewhere, so small problems are caught while they are easy to treat.

Blacksburg families are about 15 minutes from our office, a short drive down US-460. Because sealants take only a few minutes per tooth, many parents bring their children in right after school, and the visit is easy to fit around Virginia Tech schedules for faculty, staff and student families. If your child's 6-year molars or 12-year molars have recently come in, that is a good time to ask about sealants at the next checkup.

From Radford, our Christiansburg office is about 20 minutes away, and families from Dublin and Pulaski usually arrive in 25 to 35 minutes along I-81. To make the trip worthwhile, we can often place sealants during the same appointment as your child's cleaning and exam, and we are happy to schedule brothers and sisters back to back. Many homes in Pulaski County use well water with little fluoride, which makes protecting the grooves of the back teeth even more helpful.

Roanoke City and Roanoke County families make the 40 to 50 minute drive up I-81 for checkups and preventive care with our team. If you are coming from Roanoke, let us know when you book, and we will plan the visit so sealants, cleanings and any X-rays are done together whenever possible.
