Another good news story here.
DS did similar- in fact his break was almost identical to the picture of your DD.
We kept the tooth in milk and got an emergency dental appointment.
We were told they could either cement the broken piece of tooth back in place or build up the tooth using filler.
We went for the former but were warned the tooth would be weaker than if we went for the filler due to the lesser surface area of the bond.
It looked great - you could only see a thin line where the break was if you looked really closely.
However, within 6 months he face planted during a game of football and the tooth broke again (along the previous break point) and the tooth was lost in the mud.
Que another emergency dental appointment to have the tooth repaired with filler.
The result was brilliant. It was a perfect shape/colour match and even up close I can't see it. That said our dentist is an expert in detail restoration and based on friends whose has similar experiences I think this might have made a big difference.
We're 5 years on and his tooth still looks perfect. No need for a crown or veneer according to the dentist.
In hindsight I wish we'd gone with the filler first time around. It wasn't overly invasive (no injection required for example) just a bit uncomfortable as they have to keep a mouth guard (not sure if that's the right term) in for a while to keep their mouth open and lips away from their teeth.
So only real advice is to find a dentist that's trained in these restoration techniques and follow their advice on filler vs re-attaching the tooth, but it's absolutely possible to have your DD's tooth fixed and looking totally natural.
Good luck
