Do you think it’s relatively safe to crown + veneer by central incisors? (Photo)

You have an incredibly narrow maxilla and the best approach is maxillary expansion to turn your narrow "V" shaped maxilla into a wide "U" shape and expand the lower to make room for anterior teeth.

The best correction would be to correct the unerlying issue first and then correct the cosmetics permanently. Placing unbreakable zirconia crows will prevent breakage but may make other issues much worse.

When you smile I assume you have dark buccal corridors, ie the space between the back teeth and cheeks and deep nasolabial groove because there is not enough bony support for the soft tissues of your face.

More important is that your narrow maxilla is not only the roof of the mouth but also the floor of the nose and it is likely you have a forward head posture.

Do you get headaches, migraines, occipital and neck pain? The parts are all connected.

Hello. In the current situation, the lower teeth may hit the upper teeth and cause the prosthesis to break. In order to correct this situation, crowns can be applied to your lower teeth after endodontic treatment to rearrange the contact of the teeth and prevent them from hitting the upper teeth.

I do think it is safe to make those front teeth in ceramics. The ceramics are VERY strong, but the restorations also need to be adjusted to bite smoothly in all directions. For your protection and to minimize discomfort, you should be wearing a nighttime occlusal guard- at least unt you decide to straighten your teeth.
