In houseplants, the presence of fungus gnats may indicate overwatering; they may be feeding on roots that have sat in drain water too long and are thus rotting, or the gnats may be attracted to fungus growing in saturated topsoil. Consequently, allowing the soil to dry may reduce their numbers.
Different Types of Dental Caps. There are 3 different types of dental caps â gold dental caps, ceramic dental caps and ceramic and veneered gold caps. Metal-ceramic dental caps and gold caps are very effective and durable too and are particularly used for molars â the most prominent teeth that assist in grinding and chewing and are prevalently used.
Another very common area of dental work is crowns. A crown, also called a cap, is a permanent covering which is glued onto the existing tooth. A dental crown is used if the tooth is severely decayed, chipped, or broken. Crowns are also commonly used after a root canal procedure to help strengthen the tooth. Before a crown is put in place, the dentist will grind down the existing tooth and then place the crown over it.
