Ideally, a dental point means that when you close your jaws in biting position, you should have observed that the tooth from upper jaw touches the corresponding tooth from lower jaw. That makes a dental point. Hence at least there should be 14 dental points in the biting position of your mouth.
Next Steps
I'll recommend you to visit a nearest dentist and ask him to check your teeth and tell you total number of dental points.
Health Tips
So, go to a dentist and he'll give you full report on your teeth including the dental point counts.
All the best :)
