Without a CT scan I can't give you a definitive answer, but in most cases it will be possible for you to get implants in the future. However, the longer you wait, the surgery can and will most likely be more complicated possibly requiring multiple surgeries that include extensive bone grafting procedures. 

As other doctors have answered previously, without a tooth or implant, you will continually lose bone over time. If you have a good amount of bone now, you may be okay to wait 1-3 years. However, if you are already deficient in bone quantity, then you may need to address the area quickly to avoid more complex surgery in the future. 

I highly recommend if you are interested in dental implants either now or in the future, that you visit a dentist and have a CT scan completed. This way, at least you have all the information that you need to make an informed decision. 

I would definitely discuss your concerns with the dentist that completed your bonding. I do agree with you that the shade appears to be off and you can see a clear line of where the bonding stops and your tooth starts. 

This is often an easy fix, and I wouldn't expect the dentist to charge you any additional fee.

It is very common for a new bridge to feel "strange" or "different", especially a long span bridge as you have, but you should not be experiencing pain. 

Without seeing photos of your mouth I can not give you an answer on why the bridge is several mm's higher than the rest of your teeth. There could be several reasons why the bridge was designed this way, with the most common reason being the position of your upper teeth.  

However, a more important question is how the bridge feels when you bite. If you only feel the new bridge when you close then the bite definitely needs to be adjusted or the bridge replaced. A high bite can cause TMJ pain and it will only get worse unless the bridge is adjusted or replaced. 

I would schedule any appointment with the dentist that completed the bridge and/or get a second opinion.

My personal philosophy is that I would like to do the least amount of dentistry to achieve the desired goals of my patient. If your goal is to just address the one chipped tooth, then dental bonding will be my recommended treatment. I rarely recommend one porcelain veneer because it is very difficult to get a perfect color match when only addressing one tooth. 

If your goal is to address both teeth than my recommendation would be to have two porcelain veneers. Even though veneers require more of an initial financial investment, they have many advantages as compared to dental bondings. Veneers will look more life like, they will last longer, and they are more color stable. 

If you are concerned about jumping right into veneers, you could always have the bonding completed first which would address your immediate needs, and then you can always do veneers in the future. 

Final shade determination is a very difficult decision and it is a topic that I discuss at great length with my patients before starting treatment. 

It is normal for your temporary crowns to look different than the vita classic guide, and it is something that I am not concerned about. The temporary crowns are monochromatic (one shade) while the color on the shade guide is more like what your final crowns will look like as it is layered with areas that have more color and other areas that have more translucency. 

As for the final shade determination, it does appear that your lower teeth are in the greyish tones and that is why your dentist chose C1.  Without seeing you in person, it is impossible for me to determine if B1 will blend in. My recommendation is for you to go back to your dentist to go over once again your different options for a final shade so at least you have piece of mind that the color you and your dentist choose is the right color for you.
