Wisdom teeth, or third molars, are the last permanent teeth to appear (erupt) in the mouth. These teeth usually appear between the ages of 17 and 25. Some people never develop wisdom teeth. For others, wisdom teeth erupt normally — just as their other molars did — and cause no problems.
But what if you are one of those who experiences problems #pain?
If a wisdom tooth doesn't have room to grow (#impactedwisdomtooth), resulting in pain, infection or other dental problems, you'll likely need to have it pulled. Wisdom tooth extraction may be done by a dentist or an oral surgeon.
Many people develop impacted wisdom teeth — teeth that don't have enough room to erupt into the mouth or develop normally. Impacted wisdom teeth may erupt only partially or not at all.
An impacted wisdom tooth may:
• Grow at an angle toward the next tooth (second molar)
• Grow at an angle toward the back of the mouth
• Grow at a right angle to the other teeth, as if the wisdom tooth is "lying down" within
• Grow straight up or down like other teeth but stay trapped within the jawbone
Problems with impacted wisdom teeth
You'll likely need your impacted wisdom tooth pulled if it results in problems such as:
• #Toothdecay in a partially erupted wisdom tooth
• Damage to a nearby tooth or surrounding bone
• Development of a fluid-filled sac (#cyst) around the wisdom tooth
• Complications with #orthodontic treatments to straighten other teeth.
Preventing future dental problems
It's difficult to predict future problems with impacted wisdom teeth. However, here's the rationale for preventive extraction:
• Symptom-free wisdom teeth could still harbor disease
• If there isn't enough space for the tooth to erupt, it's often hard to get to it and clean it properly
• Serious complications with wisdom teeth extraction happen less often in younger
• Older adults may experience difficulty with surgery and complications after surgery
During the procedure
Your dentist or oral surgeon may use one of three types of anesthesia, depending on the expected complexity of the wisdom tooth extraction and your comfort level. Options include:
Local anesthesia. Your dentist or oral surgeon administers local anesthesia with one or more injections near the site of each extraction. Before you receive an injection, your dentist or surgeon will likely apply a substance to your gums to numb them. You're awake during the tooth extraction. Although you'll feel some pressure and movement, you shouldn't experience pain
Sedation anesthesia. Your dentist or oral surgeon gives you sedation anesthesia through an intravenous (IV) line in your arm. Sedation anesthesia suppresses your consciousness during the procedure. You don't feel any pain and will have limited memory of the procedure. You'll also receive local anesthesia to numb your gums
General anesthesia. In special situations, you may be offered general anesthesia. You may inhale medication through your nose or have an IV line in your arm, or both. Then you lose consciousness. Your surgical team closely monitors your medication, breathing, temperature, fluids and blood pressure. You'll experience no pain and have no memory of the procedure. Local anesthesia is also given to help with postoperative discomfort
Always best to consult your dentist and/or board certified oral surgeon, as everyone's case is different.
