Happy customers

We went to our cottage this last weekend, on the shore of ST-Laurent's river. A friend spent most of the time trying to catch some fish and he did get it. Many questions then have arised:

• Is this fish good for eating?
• Is our river far-off pollution?

The Q with no answer yet is : How are the teeth benefiting from eating fish? Photo showing a Dental Office, located in Eastern Townships, Quebec, Canada.
