I learned this while researching veneers and talking to clinics. No prep veneers can be a real option but honestly only for pretty specific cases.
They usually make sense when the tooth is already small, there are gaps to fill, or the tooth sits slightly inward. Stuff like peg laterals, spacing, or undersized teeth. In those cases adding material can improve shape without making everything look bulky. But the problem is some places market no prep veneers like they work for everyone. That is where people get into trouble.
If you have normal sized teeth, wide teeth, long teeth, teeth that flare out or crowded/crooked teeth, just bonding porcelain on top can make them look too big, too thick, too square and obviously fake. We have all seen those veneer results where the teeth look uncomfortably oversized and unnatural.
A lot of veneer horror stories seem to come from trying to force veneers onto cases that really needed orthodontics first.
No prep veneers are usually not the right solution if you want to:
- Make normal sized teeth look smaller
- Reduce teeth that are already long or wide
- Pull protruding teeth inward
- Straighten crooked or crowded teeth
That is usually ortho territory first, then cosmetic work later if needed.
In my case I got lucky because I had smaller teeth so I didn’t need reduction on my front two teeth. But if I had to do even minimal shaving on healthy teeth, I honestly would have passed completely. So yeah guys, think twice before getting veneers
