I agree 100% with Lola N! A bottle is not the answer. You will be creating new habits to break (you already are with the nightly attention). My brother (a pediatrician) used to say to me and to many moms and dads, that you need to discern the true need from the "I want" and tend to it properly. He had a checklist which, when followed, kept me from going crazy in situations like yours when I followed it faithfully:
Wait 5 minutes! Babies can have "bad dreams", upset stomachs, etc., so don't go running right away. They may just settle right back down themselves, and if they do, you saved yourself from creating an unnecessary scene (not to mention getting out of bed).
After 5 minutes, go and check on your child to see whether or not there is a real issue (fever, tangled blanket, poopy diaper, etc).
If there is not a serious issue, give your child a pat, tell him he's okay and to go to sleep, and then leave! Let your child cry out the restlessness or attention crave - in his own bed!
My brother used to compare these situations to a fire. As long as your willing to tend to the fire, it will continue to burn. Every time you tend to your child, you're putting a fresh log on the fire. If you just let the fire go, it will eventually burn out.
Most babies should run out of steam after 20 minutes (which seems like an eternity to an anxious Mom and/or Dad), but some (and mine have) gone an hour the first couple of times until they learned that nighttime is for sleeping - something that Mom and Dad were not going to give up easily.
Now, if your son is having real issues with teething, I would suspect his daytime nap(s) would be restless as well. If not, then your son is really playing you. If he is having teething issues that require something to gnaw on at night, then look into appropriate teething items to place in his crib. Just remember, no child has ever died from teething, so even though it will be rough to listen to his unhappiness, he will survive and so will you!
Hang in there! First borns are more about training the parent than the child. No matter how much advice you get (or previous babysitting experience), you still need live it! Good luck!
