Last week, we discussed nail biting, and the problems related with this habit. Staying on that general theme, let's discuss thumb-sucking today.
Thumb sucking is something every parent is acutely aware of - almost all children suck their thumbs at one time or another. In fact, it's a completely natural phenomena that seems to be somewhat hardwired into an infant's brain (babies have even been observed sucking thumbs in the womb.)
But why sucking? Well, early in their lives, babies need to suck to feed, whether from a nipple or from a bottle. So we can see why sucking would be a natural habit to develop. Sucking is also very calming for infants, and is believed to be a way for babies to relieve stress and anxiety.
Let me give you a few numbers on thumb sucking (these statistics are amalgamated from a variety of sources):
Numbers on adult thumb sucking are difficult to find, or even believe. This is because the habit is not something most people easily admit. But as a dentist, I know some adults still suck their thumbs.
Thumb Sucking and your mouth/teeth
The first thing I want to tell parents is... relax. Yes, there are all kinds of horror stories about thumb sucking and deformed mouths or jaws. But as I mentioned earlier, thumb sucking is natural. It's not going to become a problem until adult teeth start to come in. And, from all indications, most children will have stopped on their own by then. In fact, let's use that as our barometer. If your child's adult teeth have not started coming in, don't worry too much about thumb sucking - there's no sense in worrying about your two or three year old sucking his or her thumb. In all likelihood, he or she will stop in another year or so.
But ok, let's say your child is still sucking his or her thumb after adult teeth start to come in -- what can happen? Well, there are a few things that can happen. Let's start with the teeth themselves. Sucking one's thumb will cause permanent teeth to move. The front teeth are the ones that are most affected -- the upper front teeth will move outward, and the lower front teeth will move inward.
Also, the jaw can be reshaped, as this area is still soft and developing. In addition, prolonged thumb sucking can affect the growth of the palate (the roof of the mouth), which can lead to problems with chewing or swallowing, cause an overbite, and even affect speaking.
Now, not all of these problems are going to happen to everyone. I know adult thumb suckers who have no trouble speaking, etc. But the teeth problem is pretty much going to happen universally. Trust me, these adult thumb suckers I "know" didn't tell me they sucked their thumbs -- I can just tell. So it is something parents want to pay attention to as children age.
Aside from physical problems, many of the problems I mentioned in the nail-biting post will be prevalent with thumb suckers as well -- in short, it's really not the most hygienic thing we can do.
How to stop children (and adults) from sucking their thumbs
There are several ways to break the habit. The first step, however, is to recognize that it is a nervous habit. Thumb sucking at advanced ages is a stress reliever. So any attempt to break the habit should take this into consideration (in other words, is there something that can be done to the home environment to make thumb sucking unnecessary? Maybe, maybe not, but it's worth asking).
The popular "bad taste" solutions can be used, but personally, I'd rather see other methods used with children first. My favorite technique is a simple discussion on how it's a bad habit and needs to be broken, followed by verbal and physical reminders (like a band-aid or a mitten). In my experience, given a little time, this method (coupled with perhaps small rewards for success) has worked quite well.
You can also replace the thumb with a pacifier or other toy. While this doesn't totally relieve the problem, an "outside" device to suck on is easier to give up -- similar to using nicotine gum to stop smoking. And as any adult who has successfully done such, the "replacement" method has merits.
Good luck, and until next time, keep smiling!

I had the same experience with my son. All he loves to do is suck his thumb. I've tried all these different thing but he just switches to this other thumb. We tried putting all these things on his thumb, but after he licked it he would then wipe it in his shirt and just suck again no matter how bad the taste was.
I then just thought I would give up; I figured he isn't hurting anyone and that was his security blanked. Then I asked his doctor about it and he told me all the bad things that can happen as far as his teeth are concerned & its stops your chin development!
He told me to look at adults with no chin form and that most likely means they sucked the them...
So I searched the internet and found these pair of gloves...he loved wearing them & after a couple of months he has stopped sucking his thumb!
The funny part is we just bought him another pair because he loves wearing them...he calls himself Sonic the Hedgehog...lol

I have a theory, and feel more than confident about it after raising 4 children. Give babies what they *need* and they will grow out of it when they're ready. Sure, a little coaxing(guiding) might be involved, but it is still something they will gradually grow out of. For instance, my children went from sucking a pacifier a bit, to just having it a naptime and bedtime. Then gradually just bedtime. Then none at all. Think about it like potty-training. They will when they're ready! And not before. Then, with guidance, they can be put in training pants, and then just at night, and then none at all.
With my oldest I did everything "by the book." I took away his pacifier and his bottle(only breast fed him for 4 months) at 6months because that is what I was "supposed to do." And you know what? To this day, he has to put things in his mouth! He's twelve! I am convinced it is because I denied him the oral stimulation he needed... when he needed it. With my next three children, I let them take the lead, with some guidance from me towards the end... and they have NO oral fixation whatsoever.
For obvious reasons, the sucking instinct is strongest during the first six months of life - after that it is truly a habit and much harder to break. My children's pediatrician (who I still consider to be the best physician I ever encountered) instructed me in what to do to prevent thumb sucking and I followed it to the letter - worked like a charm. No stress on the child, no crying, no compensating behaviors.

My theory is, give a baby the exact kind of sucking they need, when they need it and they will grow out of oral fixation when they are supposed to....around age two to three.
I did both... bottle and breast. As well as pacifier if they wanted it.
I have four children. My theory? Just like your other responder... give them what they need and they will grow out of it.
