Can the tooth underneath a dental brace decay?

The abutment inside the dental braces may decay. The dental braces presumably refer to the dental crown that is placed over the abutment during fixed prosthodontic restoration. This dental crown is mainly divided into two categories: 1. Hammered crowns. This is an early technique where a metal crown is hammered into the desired shape and placed over the abutment, which then needs to be fixed with cement. Cement is often placed between the hammered crown and the tooth, and saliva can often seep into the gap, dissolving the cement. This allows bacteria to enter the original position of the cement, causing decay of the abutment. 2. Cast crowns. Currently, cast crowns are commonly used in clinical practice and are relatively close-fitting, but they are not foolproof. When there is pigmentation and a small amount of dental calculus, sandblasting may be considered for cleaning, but it is difficult to remove the general dental calculus completely. Ultrasonic scaling can remove most dental calculus, but during the scaling process, if the doctor is not careful, it may loosen and fall off the adhesive bonding agent of the porcelain fused to metal crown, creating a gap between the natural tooth and the porcelain crown, and even causing the porcelain crown to fall off. It is important to choose a reputable hospital for scaling to avoid damaging the porcelain crown. The porcelain crown is fixed to the tooth with a strong adhesive bonding agent, and it is difficult to remove. The already bonded tooth may require destructive removal, which involves drilling through the porcelain crown and removing it, generally without damaging the adjacent teeth.
