Wisdom teeth are your third molars. They’re the last teeth to form but we often see them on an x-ray, starting to develop around the age of 10 to 12 or even earlier, even though they usually don’t start trying to come in until the age of 16 or later.
Wisdom Teeth and Human Evolution
Wisdom teeth had a lot more room to come in for us humans when our lives were very different. We ate rougher foods and our jaws developed to be bigger. Wisdom teeth made a lot more sense in the past than they do no. We live differently than our ancestors and our teeth haven’t quite caught up.
Now of course people are concerned about wisdom teeth pushing from the back and moving their nice straight teeth after braces. I have some good news and some not-so-good news on that. I think the evidence is that wisdom teeth don’t cause the teeth to crowd up any more. The not-so-good news is that crowding can happen anyway, whether you’ve had braces or not and whether your wisdom teeth are taken out or not. Getting your wisdom teeth out won’t keep your teeth nice and straight without the retainers. I wish it were that simple! Teeth never stop moving, with or without your wisdom teeth.
Impacted Wisdom Teeth
Our first adult molars come in around the age of six or seven, the second molars come in around the age of 11 or 12 and the third molars, or wisdom teeth, anywhere from 16 years old to never, if there isn’t enough room and they get stuck in the gum and bone behind those second molars. When the tooth is stuck in the bone it’s impacted.
The wisdom tooth can be completely under the gum or it can come in halfway with a flap of gum covering it at the back. For most people, there is just not enough room at the back of the mouth for the wisdom teeth to come in to become useful and productive members of society. There is just no way that those wisdom teeth are going to come in properly.
For most people, it makes the best sense to have these teeth taken out. Wisdom teeth can start causing problems with infections, pain and discomfort in the teens or later.
Wisdom Teeth and Second Molars
The wisdom teeth can become a problem at an earlier age if they get in the way of the second molars. The second and third molars can kind of fight for space back there and they can both get stuck in the bone. When this happens we may have to get the wisdom teeth out at an early age, as young as 12 or 13 – to let those second molars come in. This happens, but it’s not that common.
Do Wisdom Teeth Need to Be Removed?
If you ask a hundred dentists about wisdom teeth, you’ll get a hundred slightly different opinions. I know my own opinion has changed over the years. I prefer never to remove teeth; through the course of my career, I have taken out fewer and fewer teeth to make room for orthodontic treatment and I love the results – big and broader, healthier looking smiles.
But wisdom teeth are in a different category. The space for them is all about the ultimate size of the jaws at the back and by the late teens, we have a good idea whether or not the wisdom teeth can be useful and healthy teeth for you.
I used to lean toward taking out the wisdom teeth when they’re causing you problems. I’m now leaning more toward getting them out sooner – when it’s obvious they can’t be useful teeth. Scheduling the removal of your wisdom teeth at a time that works best for you and your life can make a lot of sense – avoiding some major hassles later on.
Another factor to consider is that extracting the wisdom teeth when you’re younger can lead to better healing and fewer complications. A study has shown that girls in particular benefit from earlier removal of wisdom teeth compared to later, resulting in fewer complications, better healing. Before the age of 20 can be a helpful time for women in particular.
