Go back and talk to your dentist. Tell him that you are not able to pay all at one time, and can you set up a payment plan. As far as the crown, Gosh I have many.. The reason they usually put in a crown is because you had a root canal?? (am I right?) when you have a root canal the tooth dies, and becomes brittle. If the tooth cracks and it cracks below the gum line you will have to have it pulled. and then you run into other problems.. May I suggest that you ask them to put in a post, and later put in a crown.
If you never had a root canal, they just want to do the crown because they think that you have too much silver in your tooth, if this is the case you can put thst off for awhile.
You should get cleanings every 6months, and that is something your insurance should pay for. Deep cleanings are usually when you haven't had a cleaning in a while, and they can hurt and be expensive.
Now Wisdom teeth. Are they impacted?? Do they hurt? My 18 yr old daughter had all 4 of hers out 2 yrs ago. I still have mine and they never caused a problem.. If they aren't impacted and not over crowding your mouth, leave them alone.
Good luck, Let us know what you decide to do.
