As soon as children’s teeth break through, the so-called fissures – the dimples on the chewing surface of the teeth – can be colonized by bacteria by nature. Those fissures are about one millimeter deep and very tight (50 μm) and are therefore also very difficult or even impossible to clean. If your child is at risk of caries, the fissures can be sealed after the tooth erupts. To do so, the fine dimples are filled with a thin material, which then hardens.
If your child’s fissures have already been cavitated by bacteria, an “extended fissure sealing” can be done. For this purpose, the fissures are thoroughly cleaned and possibly expanded slightly in order to apply the sealant.
