To answer your question I will say that the future of dentistry is very bight! Dental school is a tough. Dont think that going to dental school will be easier than medical school. Many schools train the dentists and MDs side by side for the first two years. As a profession dentistry is great as it has avoided the whole health care insurance mess. It is a very diverse career that will allow you to work as a researcher, clinician, surgeon, etc. You can be your own boss, work as an associate, or work for the government. Every day is a bit different and you determine how hard you want to work based on your desired income. Most dentists work 36 hours a week and make a good living. It is physically demanding given that you will be doing procedures throughout the day that can require you to contort your body. It is also an expensive business to get into. You will probably have atleast 100k in loans and 300-500k in start up costs if you choose to buy a practice. It is a great career but you must understand that it is totally different than medicine. As the others have suggested, go shadow and ask tons of questions. However, dont be suprised if you finding shadowing to be boring. You might want to ask if you can go on a day the dentist has some interesting cases.
