think a first step could be to remove decay and bond the chipped teeth.
Composite bonding can be done in one visit, and is the least expensive option
to repair these teeth. While composite bonding will have to be redone at some
point, it is a permanent material, so if you are happy with how the bonding
looks you won't need to do anything else immediately. Long term, your situation
could involve many different areas of dentistry including orthodontics,
periodontics, implants, crowns and or root canals and extractions. The cost
will depend on what your goals are, as well as where you live. The best first
step is a comprehensive exam, x-rays and personalized consultation with a
dentist you trust.
When we sit down to discuss a large decision, we start with anything that is painful or likely to become painful. Another priority is anything that has infection, including your gums. The next step are fillings and cosmetic things to improve your self confidence in your smile. If your chief concern is the front teeth those can also be addressed first.
A dentist should be able to lay out a plan that you can both agree upon. If you wanted to get as much done at one time I would suggest OCS (sedation) to make the time fly by. If that isn't an option for you, I would at least break up the appointments into 4 separate visits.
Just like when building a house, clearing the land and building a strong foundation is step one. In this case, removing decay or hopeless teeth is the first step. Periodontal health is done simultaniously. Once healthy and stable, decisions can be made on what to do next.
This will be a large investment of money and time, but can last a lifetime.
