Cavity Filling Options for Children: Materials and Procedures

When a child develops a cavity that has progressed beyond the earliest stages, a dental filling restores the tooth by removing the decayed tissue and replacing it with a filling material. Several filling materials are available for children's teeth, each with different properties, aesthetics, durability, and costs. Your pediatric dentist will recommend the best option based on the cavity's size, location, and your child's specific needs.

Key Takeaways

Composite (tooth-colored) fillings are the most popular choice for children's teeth, costing $150 to $350 per filling.
Glass ionomer fillings release fluoride to help protect against future decay, making them useful for high-risk children.
Amalgam (silver) fillings are durable and less expensive ($100 to $250) but less commonly used today.
The filling procedure takes 20 to 40 minutes per tooth under local anesthesia.
For very young or anxious children, nitrous oxide or sedation may be used during the procedure.
Baby tooth fillings last until the tooth naturally falls out; permanent tooth fillings last 5 to 15 years depending on the material.

Understanding Cavity Filling Options for Children

Your pediatric dentist can evaluate your child's specific situation and recommend the most appropriate treatment approach. Early intervention and regular dental visits are key to maintaining your child's oral health.

When to Seek Professional Care

If you have concerns about your child's dental health, schedule an appointment with a pediatric dentist. Pediatric dentists complete two to three years of additional training beyond dental school, focusing specifically on the dental needs of infants, children, and adolescents.

Early evaluation allows for timely treatment and better outcomes. Most dental issues are easier and less expensive to treat when caught early.

Frequently Asked Questions

What should I know about children cavity filling options?

Should I see a pediatric dentist or a general dentist for my child?

A pediatric dentist has two to three years of additional training beyond dental school, specializing in the dental needs of children. For complex issues, anxious children, or children under age 3, a pediatric dentist is generally the best choice. General dentists can handle routine care for older, cooperative children.

How do I prepare my child for a dental visit?

Use positive, simple language about the visit. Avoid words like 'hurt,' 'needle,' or 'shot.' Read children's books about going to the dentist. Schedule the appointment when your child is rested and fed. Bring a comfort item like a stuffed animal.

Will insurance cover this treatment?

Most dental insurance plans and Medicaid programs cover medically necessary dental treatment for children. Coverage details and percentages vary by plan. Contact your insurer for specific coverage information about your child's recommended treatment.

How often should my child see the dentist?

The American Academy of Pediatric Dentistry recommends dental visits every 6 months starting by age 1. Children at higher risk for dental problems may need more frequent visits. Your pediatric dentist will recommend the right schedule for your child.

What if my child is afraid of the dentist?

Dental anxiety in children is common and manageable. Pediatric dentists are trained in behavior management techniques including tell-show-do, distraction, and positive reinforcement. For severe anxiety, sedation options like nitrous oxide or oral sedation are available.
