I've been having an excess of saliva lately. i feel like i'm always swallowing. is this normal? my wisdom teeth are just coming in, later than normal.

It depends: Excessive saliva is typically a transient problem and rarely a cause for concern. Most likely either your salivary glands are making more saliva than usual or you are having difficulty swallowing. Common causes include: reflux, infection, medications (like klonopin, (clonazepam) clozapine, or sinemet), pregnancy, or inflammation of mucus membranes in your mouth. Rarer causes include arsenic or bell's palsy.

Saliva: An increase in saliva production is commonly associated with tooth eruption. Typically infants that are teething drool a lot. Trouble out other possibilities it would be prudent to be examined by both an Oral & Maxillofacial Surgeon and by an ENT, an Otolaryngologist.
