Gum Diseases

Exposed gum roots

04/17/2006

Question:

The roots of teeth are being exposed. What causes the gum line to lower down?

Answer:

Exposure of root surfaces (gingival recession) is a sign of supporting tissue loss around the tooth. Generally this occurs due to bacterial infection (periodontal disease). It is sometimes due to trauma from the brushing technique. It may occur due to ill-fitting restorations or malpositioned teeth (due to anatomical location of a specific tooth within the dental arch, the hard and soft tissue support on one side of the tooth can be very thin to start with and, may not be able to handle trauma due to several reasons such as brushing, eating etc). But again it is mostly seen due to bacterial infection. It means that due to bacterial infection and inflammatory processes you are losing soft tissue and underlying bone which cover the root surface. If it continues it may cause tooth loss, it may also cause a sensitivity problem and root decay. And sometimes it becomes an aesthetic concern too.
