It is not the crown itself that can cause the bad breath. If the crown shape traps food you may develop an odor around the crown if your home care isn't sufficient to keep it clean. A waterpik works great for cleaning around crown and bridge work. If you are having odor and you are able to keep it clean, call your dentist and have him check it. If there is leaking, you could be developing decay around the crown.
Doing nothing is always an option when extracting a tooth/teeth. If you have teeth opposing the ones coming out will be affected if you do nothing though. What we typically see is the tooth/teeth below begin to errupt more. Teeth like to continue to errupt until they come to contact with something, if there is nothing to oppose them they will continue until they get loose and need to be removed, or until they touch the gums above them. I am not sure what you mean by a press on veneer, are you referring to Snap on Smile? If so, that may be an option if you are looking for a lower cost temporary fix. Other than an implant to fill the void, your other options may include a fixed dental bridge or a metal framework partial denture. As far as ease and long term stability, I would recomend going with the implants. In order to do a bridge you must have teeth on either side of the teeth extracted. You would then prepare those teeth for a crown in order to attach the bridge. A partial is a removable appliance, they work well. The problem a lot of people have with the partial is the fact that they do come in and out, they cover the roof of your mouth a bit (with the upper partial only), and they generally have a clasping mechanism that holds the partial to other teeth in the mouth. They need periodic adjustment and relines. Price wise, they will all cost around the same amount, long term - implants tend to be a better option as they do not affect the adjacent teeth.
Yes, you should be fine to eat oats with vanilla protein. The object is to avoid anything that would stain. Colored soda, teas, coffee, wine, etc... are examples of things to avoid. If your oats with vanilla are colored you may want to avoid them for now. It sounds like you are doing a good job avoiding the staining foods and liquids though, keep it up during your whitening process and you should be fine.
I would make sure the bone has had plenty of time to heal, 3-4 months will probably be sufficient. After proper healing it would be safe to place another implant. Failures don't happen often, but they do happen. Sometimes the body just needs a little more healing time before placement.
It will vary from dental office to dental office and where you live. It usually depends on their overhead costs. In our office the price for a E-Max and Zirconia crown is the same. Our price is in the mid to low range of crown cost in our area, we typically see prices from $800 to $3000. Ask around, chances are you have a few friends that have had one of these crowns who can give you a recomendation for a dentist in your area. The most important thing is to make sure they are done right the first time.
