Hi L.,
I am a Dental Assistant and just wanted to let you know that your son is not too young.All the teething guidelines are generally plus or minus 6 months.How has the rest of his teething been?did the others come in early as well? If he started teething early with all of his teeth this is now your "guideline" for him, more than likely he will be early with all of his teeth...so expect his 6 yr molars early as well..:) .It is okay and it is very common! Good luck and dont forget he may also get a low grade fever too.
