An Extra Tooth Blocks Two Permanent Teeth

After loss of a baby front tooth, a weird, pointed tooth comes out for a 7-year-old boy (Fig.1-2: *).  A normal permanent front tooth should look wide and flat.  The other baby front tooth remains in place (A).  The hawk beak-like tooth is in fact an extra malformed tooth (Fig.3 *).  It blocks the right and left permanent front teeth (#1).  It should be removed immediately (Fig.4) so that the permanent teeth will come out by themselves.

The wound heals normally 1.5 months later (Fig.5).
