Can bacteria in the mouth negatively affect good dentistry?
Yes, this is possible. Oral infection will cause periodontal disease leading to a breakdown of the membranes that hold the tooth in place. In mild cases, this leads to recession and in severe cases, to tooth loss. If you have crowns or veneers and your gums recede, this will leave a margin between the tooth and the veneer, ruining your smile. Membranes that support the tooth in place within the bone slowly break down, expensive crowns and bridges may become lose and may have to be removed.
