Wisdom teeth got their name because they tend to appear as teens turn into adults and hopefully get older and wiser – most commonly between the ages of 17 to 25 years old. As our skull grows larger the dental arch becomes big enough to accommodate these “third molars”.
Unfortunately, approximately 85% of wisdom teeth need to be removed. The reason is that lack of room in the mouth causes them to get impacted or unable to grow out properly. This can become very painful.
Not everyone has wisdom teeth. Around 35% of people are born with no wisdom teeth at all, or they may not appear. This most commonly occurs in parts of Asia and scientists have attributed it to a combination of evolution and culture – that is eating habits.
90% of people have impacted wisdom teeth. When there is not enough room for the tooth to fully enter into the mouth, this situated is known as “impacted”. This causes painful pressure between the new wisdom tooth and the existing molars. This stress can also damage the existing teeth.
This “crowding” at the back of the mouth results in difficulty cleaning the teeth effectively and can result in infection and a built up of bacteria.
Diet contributed to impacted wisdom teeth. The teeth of early humans had more wear due to their more challenging diet. Today, the kind of diet that people have is a lot easier for the teeth so the teeth don’t wear down as much – they need more space!
