After a small piece of incisor is lost, the following three treatment methods can be used: First, the simplest is to carry out resin-based filling, the treatment time is short, usually the same day can be completely filled, does not affect the aesthetics, but resin-based filling in about 5 years will occur aging, affecting the aesthetics, need to replace the material. Second, take the minimally invasive aesthetic veneer restoration, currently the most suitable for this case of missing incisors, and the amount of teeth removed is relatively small, but its cost is higher. Third, take porcelain crown restoration, if the incisor lost a small piece, can not be filled by resin or resin filling is easy to fall off, you can also consider doing a porcelain crown wrapped around the tooth, but its disadvantage is the amount of tooth removal more.
