Food impaction is the cause of the cavity in your wisdom tooth. Since it is the last molar you can decide whether to retain it by filling etc or remove it.
Attrition occurs with age and sometimes due to the bite it may be more in some people.
Health Tips
If you grind your teeth at night that may be causing attrition. Get a nightguard in that case.
