A peas sized lymph node in the sub mental can be secondary to the infection any where in the front part of the mouth. The lymph from the front of the mouth is commonly drained into the sub mental (below the chin) and sub mandibular region (below the mandible). Hence it must be because of some trivial infection in this region that it has got enlarged. Try taking antibiotics (such as Augmentin), drink plenty of water and maintain your oral hygiene.
