Wisdom teeth normally erupt between the ages of 18 to 24 years of age.
It is common for wisdom teeth to be impacted, meaning there is no space for them to erupt. It is not normally common for wisdom teeth to erupt into the right position, even if space is available.
The reasons for not having this space are:
Our soft diets do not cause wear on our other teeth
It is vital to save our other teeth as they have normally erupted into the correct position, do few other teeth are being extracted
The lower jaw has not grown enough to accommodate the wisdom teeth
Do I Need My Wisdom Teeth Removed?
Wisdom teeth need to come out if any of the following problems are occurring:
When an impacted wisdom tooth starts to push through the gums, an infection can start around the top of the tooth. Infection and inflammation (swollen red gums) can cause pain, swelling and jaw stiffness.
A wisdom tooth may push nearby teeth out of their correct position, however they are not believed to be associate with crowding of the lower front teeth.
Sacks of fluid called cysts can form around the tooth and may displace the tooth. The cysts can destroy bone and damage surrounding teeth and gums.
Damage to nearby molars
An impacted wisdom tooth may keep pushing against the molars next to it. This often leads to serious damage to both teeth.
Why Do I Need All Four Wisdom Teeth Removed?
The impacted tooth causing problems needs to be extracted, but so does its opposing tooth. This is because teeth keep moving until they hit something. So, if only one tooth is extracted then the opposing tooth will keep moving (supraerupts) until it hits the gingiva of the extracted tooth, causing problems.
As it supraerupts, it also increases its surface area, causing more food and bacteria to accumulate around the tooth. Therefore, having the two opposing teeth out at the same time saves the extraction procedure and consequent healing time from having to occur twice.
The difficulty of the extraction procedure determines whether they can be extracted at the surgery or in a hospital. Your dentist can discuss your options with you. It is also important to know the complications associated with the procedure, which will be explained further when you visit Oasis Dental Studio.
