As I read your question you need the services of a hygienist.

In the latest Safeguard the incoming president of the Hygienist Group is interviewed. Check out her comments. the HAZANZ web pages have registered professionals. I would disclose that Suzanne is a personal friend who I have known for about 20 years.

Whenever I consider this issue I often think about motor vehicle accidents. Is driver error ever a factor in motor vehicle accidents? Insurance companies contemplate this every day when they make a decision on which insurance policy is to be credited (or perhaps debited) with the cost of the repairs.
