Regular cleanings and checkups by the dentist are important, even for primary teeth, or baby teeth as they are commonly known. Many people think that you do not have to worry about these teeth, as they fall out and are replaced by permanent ones. However, with poor oral hygiene, these teeth can become so heavily decayed that it can lead to a dental abscess and affect the permanent teeth underneath as well. Also, your dentist has a chance to check for other issues that may benefit from earlier treatment or orthodontics, and to ensure a child's oral hygiene is adequate.
