Composite Bonding Restoration, How Long Until It Starts Feeling Normal?

It is possible that you will simply need to adapt.  If the bonding feels bulky, then it will always feel bulky.  If they don't feel smooth like enamel, they may never get smoother.  This feeling is one of the reasons bonding is considered inferior to porcelain veneers.

It appears you are very enthusiastic about the cosmetic result and that's great!  A few questions to have a better understanding:  Was local anesthesia required and was any tooth structure/enamel removed?  When do they feel unnatural?  Is it when you bite, chew, drink, grind or sensitive to hot/cold?  Or is it all the time?  If it's chewing, biting or grinding, the bonding can be adjusted to eliminate any interferences.  If they feel unnatural with your tongue, it may be an issue of the surface texture where it's rough or "gritty".  This can be easily fixed with special polishing techniques and instruments that utilize varying textures and coarseness from coarse to very fine, and pastes to create smoothness and natural luster.  It could also be the contact between the adjacent teeth;  the teeth may feel very "tight" with one another.  When you floss does it shred or get stuck in between the teeth?  If that's the case, perhaps have your dentist very gently recontour and polish in between to create a little more space.  But this must be done very carefully because you do not want to strip too much composite away, otherwise it will open a gap between your teeth.  You always want to have contact and some resistance as you are going up and down with floss.  Hope this helps, good luck!

If you have ever had braces you probably remember how weird they felt when they were first placed.  It took a while to adapt and get used to the brackets on your teeth, but it happened.  Also, when you have the brackets removed when your braces are done, again, it probably felt weird, like something was missing and there was an odd void between your lip and teeth.You are capable of adapting to the different tooth shape/size.  However, if there is something about them that is bothering you, length, thickness/bulkiness, then let your dentist know so they can best help you get comfortable.
