Decay on wisdom tooth and adjacent molar.
Optimal time for wisdom tooth removal. Roots are approximately 1/3 formed. Age 16.
Wisdom Teeth & Problems They Cause
How Wisdom Teeth are Removed
Four Types of wisdom tooth impactions
1. Full Bony Impaction
2. Soft Tissue Impaction
3. Horizontal Impaction
4. Partial Bony Impaction
AKA Third Molars
At Nothing But Wisdom Teeth, our main focus is the removal of, you guessed it, wisdom teeth of all shapes, sizes and levels of impaction.
Wisdom teeth are the last teeth to erupt or "come in." They are also known as third molars because they are literally just that — you have two regular molars in front of each wisdom tooth. Most people have four wisdom teeth, but it is not uncommon to have fewer or even a couple more! (Are people with more wisdom teeth wiser, or less evolved?!) The human skull has changed size over time, leaving less room for wisdom teeth to fit in the mouth. Because of this lack of space, wisdom teeth can cause many problems including the following:
- Roots become embedded in jawbone
- Full roots can cause jaw fracture
- Difficult to clean that far back
- Develop cavities easily
- Adjacent teeth can be affected
Infection & Cysts
- Chronic gum infection can occur
- Best to remove source of infection
- Cysts are fluid-filled sacks around teeth
- Can destroy healthy bone if untreated
The best time for removal of wisdom teeth is when the roots are approximately
1/3 - 2/3 formed as pictured to the right. This usually occurs between the ages of
14 to 18. The unnecessary teeth are removed under IV moderate sedation,
allowing the patient to sleep through the surgery and wake with no recollection of
it. Below we've outlined the different levels of wisdom tooth impactions.
- This means that the wisdom tooth has grown into the mouth completely.
- You should be able to see the entire crown of the wisdom tooth, much like
the rest of your teeth.
- Oftentimes, even fully erupted wisdom teeth need to be extracted because:
- Can be very hard to clean properly
- May become decayed and require fillings or more expensive root canals
- Can cause decay on adjacent molars that you do need
Soft Tissue Impaction
- Upper wisdom teeth are often soft tissue impactions.
- The tooth is completely covered by gum tissue.
- Partial Bony Impaction - a portion of the crown is embedded in the jaw bone
- Full Bony Impaction - the entire crown of the wisdom tooth is embedded in
the jaw bone
- Lower wisdom teeth are often horizontal impactions
