Hard palate is the partition between the nose and floor of the mouth. Embryologically, hard palate is formed by the palatine process of maxilla and the horizontal plate of the palatine bone. Anterior portion of the hard palate contains irregular ridges which help during feeding. Hard palate continues posteriorly in a soft portion called soft palate.
Abscesses of hard palate are known. The etiology may be trauma, ulceration, secondarily infected nasopalatine cyst or infected tooth. The line of treatment will be antibiotics and anti-inflammatory followed by incision and drainage.
