if done properlly, it boosts self image and confidence, and is also very benifical for your dental future....
Ooops! Completely missed your real questions...!!
It might boost your self image and confidence. Depends on how you are feeling now. Are you embarrassed to smile? Do you find yourself hiding your mouth/teeth when you talk?? Do others make comments about your teeth or do your teeth distract others from what you are speaking?
If so, than cosmetic restorations may be helpful.
As far as beneficial for your dental future - depends on what exactly is the trouble that you present with now. If you have active decay and ignore it, it will not go away. It will progress. Deeper into the center of the tooth and into the nerve. Can also spread to neighboring teeth. Left untreated, root canal therapy and full-coverage crowns w/ posts are often needed. Otherwise, extractions are done.
When teeth are lost (extracted), surrounding teeth shift around. If you are missing a tooth on the bottom left, for example, the tooth/teeth in back of the space start to drift forward. Often they 'tip' forward. Sometimes they tip so far forward that they lie flat. These teeth then need to be removed as well. The teeth above the space where the lost tooth/teeth were very often 'super-erupt' - continue to grow down and can become loose because then there is little bone holding them in place.
Simply put, one problem often begets another. Also, if you lose teeth at a relatively early age, and do not somehow fill in the space, bone - especially on the lower jaw - tends to flatten. This flattening makes restorations in later life more difficult. People who get full lower dentures before age 30 usually have a terrible time in their later years.
You need to decide for yourself what impact your teeth are having on your life now and what you hope to achieve with reconstruction. Discuss your thoughts, feelings, and hopeful outcome with your Dental Team.
Most Dental Reconstruction/Rehab cases are treated by a team. Often a Prosthodontist will lead the team which may also include: Periodontist, Oral Surgeon, Endodontist, Orthodontist.
Ahh!! Another tip: Ask the dentist what he/she would do if it was his/her own mouth that presented in this manner. What if it was his/her sibling or child? What would they recommend in those cases. What if same situation but money was a big issue?
I hope some of this information is helpful for you.
Best wishes for a bright smile!
