Bring the piece: your own tooth is often the repair
When a front tooth breaks cleanly, the missing piece is usually somewhere nearby, and it is worth finding. The international trauma guidelines are direct about it: if the fragment is available and intact, it can be bonded back onto the tooth, after soaking in water or saline for 20 minutes to rehydrate it [1]. Your own fragment already matches the tooth in colour, translucency and the way it wears, because it is the same material. If the piece cannot be found and your lip was cut, the same guidelines advise an X-ray of the lip, since fragments can end up embedded in it [1].
It is worth being honest about what the long-term evidence shows. In a German university study of fractures that ran below the gumline, a harder situation than a chipped edge, 76.5 per cent of the injured teeth were still functioning after an average of 8.5 years, and among the teeth that survived, the bonded fragment itself was still in place in 66.7 per cent after an average of 9.5 years [4]. Complications were common, and the authors describe reattachment as a long-term temporary treatment: a way to keep the tooth and postpone more invasive work, often for years. For a young adult, those years matter.
