user, its not clear why caps for all teeth are needed. Clinical condition of your teeth and diagnosis of problem is important, based on that treatment plan can be made.
Also cost of treatment can not be commented as it depends on various factors like type of cap (crown) being used etc.
For more clarification, kindly elaborate your clinical findings mentioned on your prescription. Based on that we can advice.
Or you can contact us through private consultation on Lybrate.
