Your pediatric dentist recommends a cap ( crown) for your child. You are wondering why does little John/ Kierra needs a cap rather than a filling. There are reasons behind this recommendation. Some of them are as follows:
1. If the cavity is bigger in size in baby teeth sometimes it can best restored with a crown.
2. Your child may be at high risk of developing cavities therefore dentist chose to recommend crown as a more durable option.
3. Crowns usually go hand in hand with baby root canal treatment ( e.g pulpotomy)
1. If the tooth is formed defective like severe enamel hypoplasia then crowns can be placed as preventive measure.
So please ask your provider about his/her thought process behind this recommendation.
