Too Early for Teething?

Baby boy is 10 weeks and recently started:

-drooling excessively

-being extra irritable during the day

-getting too little sleep (9-12 hrs per 24hr period)

-waking every 1.5-2 hours at night (was doing 2-3)

The drooling and lack of sleep worries me most. Is it possible he could be teething at 10 weeks old?
