Patient's Query

Hello doctor,

When it comes to having a tooth extracted, I often experience difficulty getting numb in my lower jaw. Despite getting the maximum dose of anesthesia, there have been incidences where I do not get enough numbness, especially in my lower jaw. In such circumstances, what should be the course of my action? Should I go ahead with the procedure even if my lower jaw is not fully numb, or should I request my dentist to reschedule the treatment? I am concerned about if my asking for reschedule would irritate the dentist and if rescheduling would be an inconvenience to my dentist. Kindly help.

Hello,

Welcome to icliniq.com.

I have read your query and understood your concern. There can be many reasons for not having enough numbness in your lower jaw. These include increasing age, smoking, drinking alcohol, diabetes, or an abscess in the tooth that has to be extracted. With regard to this, I suggest that if you are a smoker, then quit as soon as possible. If you have diabetes, inform the doctor and take medication prior to the treatment to control it. If you have an abscess in the tooth to be extracted, it may hinder the anesthesia from working effectively in that specific area. In such cases, it is important to cooperate with the doctor. I recommend asking the doctor to use liquid nitrogen or anesthesia sprays. After the tooth extraction, take the prescribed painkiller one hour after the extraction and carefully follow the dentist's instructions.

The Probable causes

The probable causes can be smoking, drinking, diabetes, aging, or an abscess in the tooth.

Investigations to be done

Investigations to be done include an X-ray of the tooth to be extracted.

Differential diagnosis

Differential diagnoses include periapical abscess, drinking habits, and facial paralysis.

Probable diagnosis

The probable diagnosis is a periapical abscess.

Treatment plan

The treatment plan includes following the instructions given after extraction and using painkillers after an hour of extraction.

Preventive measures

Preventive measures include not spitting after extraction, avoiding smoking or drinking, consuming soft semi-solid food, and drinking cold water or eating ice cream after an hour of extraction.

Regarding follow up

Regarding follow-up, visit the dentist after seven days of extraction.
