1. Extract Another Tooth
Wisdom teeth, or third molars, either erupt in the teenage years or are unable to do so. Because they are the last teeth to erupt, depending upon the size of the jawbone, they may not have room to take their natural places. If not, they can become trapped in the jawbone where they originated. The only way to prevent an impacted tooth in a child is to make space for the incoming molars.
Unfortunately, unless teeth have already come in sporadically and number fewer than 28, the only way to create more space in a tight jawbone is to remove a viable tooth through extraction. Unless there are already signs of infection or other problems with the emerging wisdom tooth, dentists will not recommend this procedure. Doing so will change the configuration of the bite, possibly to detrimental effect.
2. Pay Attention to Genetic Susceptibility
The incidence of wisdom tooth impaction can be traced, in part, genetically. A father and mother who both have smaller-than-normal jawbones or larger-than-normal teeth are likely to produce similar offspring. If this describes you and your mate, or if you both suffered through severe complications from impacted teeth, you may well pass along the condition to your child. Even people with average-sized jawbones, however, can still experience impaction due to crowding or uneven eruption of the other teeth.
3. Prevent Problems Associated With Impaction
When it's too late for corrective surgery because your wisdom teeth have already become impacted, take steps to prevent pain and infection that may lead to extraction. Attentive oral hygiene will keep the impacted area clean and free of bacteria, which reduces the risk of internal infection. Brush twice daily with a soft-bristled toothbrush, and floss daily if your dentist says it's okay.
If the impacted area is sensitive, an antibacterial mouthwash or simple rinse with salt water is a supplemental preventative that feels good too. Take aspirin or ibuprofen right away if you notice any swelling. This will reduce inflammation and prevent any accompanying pain.
