Wisdom teeth are an extra third set of molars that often appear during late adolescence and adulthood.
The mouth often doesn’t have enough space for wisdom teeth and they end up causing pain, or structural damage to other teeth in the mouth.
They can also increase the risk of decay. If this is the case, your wisdom may need to be extracted.
When wisdom teeth start to break through the gum, there generally isn’t enough room for them to fit.
Other problems occur when they come through at an angle or fail to develop correctly which may cause significant issues for the rest of your teeth.
This is especially the case for the second molars at the very back of the jaw because of the extra pressure and the fight for the limited space that’s available.
As mentioned, decay is another major problem. When new wisdom teeth knock the others off balance, it creates small spaces and slightly misaligns the jaw.
This, in turn, alters biting and chewing. Food and other debris can get trapped inside cavities, significantly increasing the risk of decay and further dental problems later on in life.
That said; your dentist might recommend that you get all of your wisdom teeth removed.
