Fear of Impacted Wisdom Tooth Extraction: When a University Hospital Referral Is Needed and Sedation

Do impacted wisdom teeth have to be removed at a university hospital?

Not necessarily [1]. Even horizontally impacted wisdom teeth are sometimes removed at dental hospitals and dental clinics with board-certified oral and maxillofacial surgeons, and university hospitals are the higher-level institutions to which cases made complex by nerve proximity or general health are referred [1]. In other words, impaction does not automatically mean a university hospital; the first step is checking the nerve and bone positions with CT and deciding whether it can be done at the clinic or needs referral to a higher-level institution [1]. DentStat analyzed 90 patient comments on fear of extraction and avoiding university hospitals. Complaints combining fear of pain and the burden of waiting stood out, such as being told to go to a university hospital because all four were impacted and feeling scared, or having to wait months at a university hospital [3].

When is a case referred to a university hospital?

Cases are referred to a higher-level institution when the tooth is very close to the nerve canal or fully impacted and therefore complex, or when uncontrolled systemic illness or bleeding risk requires management [2]. Lower wisdom teeth are sometimes close to the inferior alveolar nerve, which provides sensation, and if imaging shows they are close, it may be decided to perform the extraction at an institution with the facilities and staff to lower the risk of injury [2]. Young patients who find it hard to cooperate and patients with underlying conditions that are difficult to manage may also be referred [2]. Conversely, without such complex factors, it is often treated at a dental clinic that offers oral and maxillofacial surgery, so rather than putting it off because of wait times, the starting point is having the difficulty assessed [2].

I am afraid the extraction will hurt a lot and that the anesthesia will not wear off.

Pain during the procedure is mostly controlled by local anesthesia, and the anesthesia wears off over time [1]. Much of the fear of extraction often comes less from the pain itself than from not knowing about the drill noise or the process of sectioning and removing the tooth, so having the procedure explained in advance helps reduce anxiety [1]. Worry that the anesthesia might never wear off also came up often in the comments [3]. The effect of local anesthesia disappears after a certain time, and temporary reduced sensation that can occur with extractions near the lower jaw nerve is a separate matter from anesthesia and usually recovers [2]. If fear is making you put off care altogether, talk with the dental clinic, including about ways to ease fear [1].

Can the extraction be done under sedation (“sleep anesthesia”)?

Extractions are sometimes done with sedation, provided indications and general health are checked first [2]. Sedation is sometimes chosen for extreme fear or when several impacted wisdom teeth are treated at once, but whether it is possible is decided after assessing systemic illness, medications, airway condition, and other factors [2]. Sedation has a different purpose from local anesthesia, which blocks pain; it is an aid that reduces anxiety and memory, and doing it in a setting with monitoring equipment and an emergency response system is directly tied to safety [2]. There are accounts in the comments of having all wisdom teeth removed at once under sedation [3], but indications and safety conditions differ for each person, so this is something to confirm through consultation [2].

Can children have teeth extracted?

Young patients also have extractions, and step-by-step explanations and sedation options are used to ease fear [1]. However, depending on the degree of impaction, cooperation, and general health, they are sometimes referred to an oral and maxillofacial surgeon or a higher-level institution [2]. A parent understanding the procedure and explaining the process to the child in advance is described as helping with cooperation and easing fear [1].

Common myths and facts

Some believe impacted wisdom teeth can only be removed at a university hospital, but depending on difficulty, they are sometimes treated at a dental clinic that offers oral and maxillofacial surgery, which can reduce the burden of waiting [1]. Another common idea is that extraction is always terribly painful, but pain during the procedure is controlled with local anesthesia and sedation, and knowing the process helps reduce fear [1]. Conversely, the belief that it is fine to keep putting it off because you are scared calls for caution, since inflammation or cysts can form around impacted wisdom teeth or affect neighboring teeth, so leaving them is not always a safe choice [2].
