Thanks for sharing your concern.
It is good idea to go for cosmetic correction of teeth even if you do not experience any pain as it is your front teeth.
now the first thing that You should know is whether your tooth is vital or non vital.
As it has remained all these years symptoms free that means your teeth is vital. In this case mere cosmetic built up will help you a lot.
alternatively, if required you can go for prosthetic crown too for your teeth.
A visit to the dentist
will give you exact picture of your tooth.
In any case, if the tooth has suffered heavy trauma and is non vital then you will have to go for root canal
followed by prosthetic crown.
but do not worry, in either case your front teeth can be beautifully saved.
hope it helps.
