This took about 2 minutes of googling lauric acid and tooth enamel:

I wouldn't worry so much about the ph of lauric acid, unless that is what you pull with.

I would test the ph of the coconut oil that I was using. If the ph is 5 and below, I'd say that in would be probable that some people would get dental caries/ de-mineralization and loss of tooth enamel.

If you hava a ph meter, I would appreciate you telling us the ph of the coconut oil that you use.

I would avoid using litmus paper since it can be very innacurate and the results are too subjective.

I read that link, but it's not definitive enough to come to a conclusion.

We don't know what the ph is of the specific coconut oil that Singer7 uses, nor do we know what the ph of the tooth paste that contains the coconut oil.

All oils are fatty acids. 100%
