Indention after a hematoma

[LeeleeCP]

My three year old fell into the edge of a glass table two weeks ago. When it happened, there was an immediate intention in her cheek that soon swelled and bruised significantly. Luckily, she hit right under her cheekbone, so there was no bone trauma. Her doctor said she had a large hematoma on the inside of her cheek which would take up to a month the heal. Now that it is beginning to heal, it is leaving behind an indention, right where the original one occurred. This affects her smile and the whole look of her face. The indention is about 3/4 inch long, right under her cheek bone. Is there anything I can do to essentially puff it back up?

Thanks
