The bigger of the two front teeth is tooth #9. It is a crown that was cemented to a dental implant abutment.
Unfortunately, it is not rare when a dental implant is done in this region for the final crown to be bigger/longer. Fortunately, in this particular situation, this asymmetry is not visible when this man smiles. The techniques used to restore dental implants in my dentist office, Palm Harbor have changed favorably over the more than two decades that I have been placing and restoring dental implants in Palm Harbor, Tampa Florida.
