Hi...First of all you need to mention the reason of enameloplasty. & We have thick enamel layer. If enameloplasty is done 0.5 mm then it would not cause any bite problem & sensitivity. So don't worry no need to restore it too.. For any further information, you can consult me.

Why did you get an enameloplasty done at such an younger age? Were your teeth sharp edged or did you get an RCT on the opposing molar? If you are not having any sensitivity after getting enameloplasty then you need not worry about it. Our teeth usually tends to get back in occlusion if opposing teeth are present. Note:- If you got enameloplasty done due to sharp edged teeth, your teeth might get sharp edged again. You can discuss it with your present dentist or talk to me regarding the same. I would be happy to help.

Although addition can be done, but it depends on when was the enameloplasty done and how much was it. Usually enameloplasty is less than 0.5 mm for it to be non sensitive . Also Bite usually gets settled in few months. So if its not troubling you , you can wait bite usually settles on its own

Visit your dentist to get original length of tooth,so that it doesn't interfere with occlusion of tooth.
