I suggest you bonding, but it would be better to do this with porcelain laminates, not composite.and prepless laminet
Your weak teeth may be due to genetics or nutrition. The most suitable thing for you is to clean the decayed teeth and make crowns of all teeth and you should pay attention to the care.
I would like to recommend prebless lamina before veneer. Your teeth will not be cut and it will fit better in the mouth.
In cases like yours, we recommend laminated veneers, but it comes in two types, preb and prepless We can decide which one will be appropriate during the inspection.
If you don't want a crown, the only thing left to do is laminate veneer. In this, at least 6, normally 10 teeth are applied in the upper jaw.
