What happens after Extraction?

All of the following problems can arise after tooth extraction: Effects on Oral Health

  1. Bone loss occurs at the area where tooth is extracted
  2. Bone height and width of jaw will be lost in the following months after extraction. (Figure 1)
  3. Biting irregularities due to lost tooth can cause insufficient chewing and negatively affect eating habits even to the extent of having an effect on nutritional balance
  4. A missing tooth makes the opposite tooth useless which can compromise functionality
Effects on Aesthetics  
  1. Bone loss causes the gum line to collapse, which can make one’s smile less appealing or turn a smile into a frown. (Figure 2)
  2. Lips and cheek will lose support thus appearing aged and collapsed
Effects on Future Restorations  
  1. Bone loss following tooth extraction may make it difficult for future restorations to work as implants, dentures or bridges require good bony foundation to function properly. (Figure 3)
  2. Restoring the lost bone requires surgical bone grafting procedure which causes additional cost, time and pain.

The jaw bone surrounding the teeth, called “alveolar bone” supports the teeth. After an extraction, the alveolar bone naturally begins to erode away since it is no longer needed to support the tooth that has been removed. (Figure 4)

Bone height loss can be up to 1.5 mm in 3 months and decrease in the width of alveolar ridge can be as much as 50% within 12 months. Even with complete healing, there is generally some erosion or resorption that can lead to shorter and thinner surrounding bone than compared to prior extraction. This can cause gum tissue defect which can lead to significant cosmetic and functional problems.
