Every patient presents with a different situation and their needs differ accordingly. Yes.... sometimes teeth are too far gone for veneers and a crown might be the answer. In a smile makeover of the upper 6 or 8 front teeth it is not unusual for some of the teeth to need crowns and some need veneers. As long as the cosmetic dentist knows how to handle the case and uses a terrific dental ceramist you won't be able to tell which teeth have veneers and which teeth have crowns. They will be a dead match with each other.
Without SEEING your situation it's not possible to even guess the cost. Are the teeth worn and broken down from grinding? Are they broken down from big cavities? From a fight? Car accident? Are the back teeth in a stable bite position or are they broken down too. Maybe even missing some back teeth? Is there any gum disease present? Before a dentist can answer your question there are many questions the dentist needs answered first. Wish I could have been more help.
While it's a great idea to want to look better through cosmetic enhancement of your smile....it will probably have no effect on bad breath. The causes of bad breath should be looked at separately. Could be anything from brushing and flossing habits to periodontal disease or more.
Depends on the individual. Most people are fine and go back to work immediately. Some might need an additional day. It's not as stressful as one might think.
Most dentists can provide you with a couple of options to whiten your teeth a little..... or more than a little..... depending on what you want. Small chips in teeth can be treated most conservatively with Direct Resin Bonding. How well this works depends on what is causing the chipping and if it is an ongoing threat to the teeth. Clenching, grinding or even nail biting can seriously damage any type of cosmetic dentistry.
