If your retainer doesn't fit anymore then that means that your teeth are shifting. You should go see your orthodontist as soon as possible and depending on how bad it is you might need to get braces again.
You should ask your dentist. You shouldn't need to replace your retainer at all unless it hurts, doesn't fit for some reason, or your orthodontist says to.
Yes, the retainer will still fit properly. The filling fills a hole on the inside of the tooth, and the retainer covers the outside of the teeth so the cavity is not affected.
Yes. Technically a crown should be made to closely remember the existing tooth therefore fitting the existing retainer. However, depending upon why the tooth requires the crown the retainer may or may not fit WELL. The ideal situation is to have the crown done and the retainer remade to fit the new crown PERFECTLY. The compromising situation is to have the crown done and adjusting the retainer to fit the new crown IF POSSIBLE. Sometimes the retainer is held in the mouth by a clasp, connector, or portion of the retainer that is unable to be adjusted or changed BECAUSE of the location/shape/size of the new crown. Remaking the retainer may be simply a longer-lasting, better-fitting, easier, or cost-effective way or any combination of such to have a FUNCTIONAL retainer. Remember, the goal is to fix the tooth that requires the crown AND to keep the teeth in their proper positions.
You can't, any qualified dentist will not fit you with a retainer if a retainer is not needed. If they did so they could be sued.
No. The retainer is used to keep the teeth in place, not move them. The retainer will probably just not fit as well now.
Sometimes you can warm a Tupperware lid that does not fit well anymore and it will stretch to fit. Warm this in hot water or in a microwave to see if it can conform to fit as soon as it comes away from heat.
