As adults, our current dentition (the arrangement of teeth) in each jaw includes four incisors (for biting), two canines (for tearing), and four bicuspids or premolars, and sixmolars including wisdom teeth (all for grinding) – that’s 32 teeth. But most jaws today are much smaller and have the capacity for only 28 teeth.
There are many theories for why our jaws became smaller, including that the jaw accommodated its structure to enable speech. When it became smaller, the change resulted in less space at the back of the teeth known as the retromolar space. So, as you can see, something has to give! And most of the time, it’s the wisdom teeth.
Wisdom teeth begin to form at around age nine and completely maturing by 18-21 years. Usually, by our late teens, the jawbone has reached its adult size. This is where the problems begin as the jaw often isn’t big enough to hold the wall of our developed teeth. As a result, when wisdom teeth start to erupt, the space is too limited, and wisdom teeth can find themselves in several predicaments.
Simply put, when wisdom teeth try to erupt into the mouth when there is no room for them, they put pressure on existing already-erupted teeth. This can cause great discomfort or pain. Sometimes wisdom teeth are positioned sideways and push on the roots of your back molars. Sometimes they make other teeth shift – definitely what you don’t want to have happen, especially if you already had orthodontic treatment. Despite the reason these teeth don’t come in to place correctly, we call them “impacted.”
Complications Of Wisdom Teeth Emerge When They Become…
- Trapped – Sometimes, wisdom teeth become trapped in the jawbone below the gumline. When it happens, aching and pain will occur. You cannot diagnose this yourself as the positioning of the wisdom teeth can only be seen with the aid of x-rays.
- Sideways – This is when the wisdom tooth wants to erupt, but it’s positioned to grow sideways and push forward against the second molar. Again, great discomfort and pain. This can cause other teeth to give way and shift position, possibly disrupting the alignment of all your teeth, not just the ones at the back of your mouth.
- Partially erupted – The tooth’s crown may only partially break through the gum, as it can be held back by the already-in-place second molars. Often, the molar may not put pressure on its neighbors.But it is very difficult to clean and impossible to floss, leaving it susceptible to serious decay and infection further down the road.
- Misplaced – A wisdom tooth may remain in the bone with misshapen or misplaced roots that can grow dangerously close to a sinus cavity.
What may happen when wisdom teeth become impacted? While you likely won’t experience all these symptoms, you will definitely experience some…
- tooth discomfort or pain
- shifting teeth
- sore gums
- face pain
- jaw pain
- reduced ability to open mouth
- gum disease
- bad breath
- jawbone cysts.
Predicting the future of your wisdom teeth? It’s difficult to predict when or if your wisdom teeth will give you problems, but regular x-rays can provide us with a good indication. Removal at a younger age before complications develop means easier extractions and a much faster recovery time.
How do we treat impacted wisdom teeth?No one can tell when an impacted molar will cause trouble, but trouble usually comes. The key to avoiding discomfort and complicated treatment is with x-rays so that the wisdom teeth can be removed before that happens. It’s one of the most common oral surgery treatments.
