How Much IPR Can Be Done to One Tooth?

The black triangle space that you have is because you have 2 triangular teeth sitting close to each other and only contacting at the tip. The bone and soft tissue is also missing due to the initial crowding.

Whether you have 1-2 mm of enamel, it is not advisable to do more than 1mm IPR between 2 teeth. This allows the triangular contact points to be separated and the teeth brought closer together. The space may never be closed unless you want rectangular teeth as a result.

Too close and the roots may impinge on the bony separation and cause further gum shrinkage.

I never do more than 0.5mm  IPR in most cases and only when the teeth are nearly straight or there is a blindingly obvious big space present.

Your problem is not solved with IPR the length of the tooth, but only the half close to the biting edge.

send me a picture and I will advise

 

Your Dr best knows how much can be taken off. The enamel is thick and .5mm is not much. It seems a consultation is needed so you can feel comfortable with your treatment.

its your teeth so ask questions

Teeth generally have 1.5-2 mm of enamel on them so you can safely do more than .5mm of IPR on a tooth.  Removing black triangles can be tricky though.  You can also consider veneers or bonding.
