Hello,
As per your concern u are most conscious about your beauty and appearance. U are in a thought that it's a back tooth no one will notice about it.
But think of Ur health that is going to be at danger due to loss of the most important tooth for chewing.
The consequences of this is.
1. U start chewing on one side where u have complete set of tooth which leads to single side tooth wear and at later time causing sensitivity due to severe attrition
2. When u leave the missing tooth the tooth adjacent to it and the opposing tooth drift to the missing space causing u distrubence in occlusion which leads to in untreatable TMD disorder at later date.
3. Coming to your age factor u have much more to do with these available tooth surrounding the missing area. But eventually they to will get loose and fall off due to drifting.
Not only these there are many other things
So never neglect a missing tooth u have to repent for the delay u make for replacement of it
Next Steps
