"BEWE score"

Basic Erosive Wear Examination — a scoring system used to record and monitor the extent of tooth surface loss from erosion

"A BEWE score of 9 triggered a dietary assessment to identify the source of acid causing tooth wear."

"tooth mobility"

The degree to which a tooth can be displaced from its normal position in the socket when lateral or vertical force is applied

"Grade II tooth mobility was noted on the upper front teeth, consistent with advanced bone loss around those roots."

"informed consent"

A process by which a patient is given clear information about a proposed treatment and voluntarily agrees to proceed

"The dentist obtained informed consent by explaining the procedure, risks, and alternatives before the extraction."

"postoperative instructions"

Written or verbal guidance given to a patient explaining what to do and avoid after a dental procedure

"The nurse reviewed the postoperative instructions and advised the patient not to rinse vigorously for 24 hours."

"dry socket"

A painful condition after tooth extraction where the blood clot dissolves or dislodges before healing is complete

""You may experience dry socket if you smoke or drink through a straw — let us know if the pain increases after day three.""

"sensitivity to cold"

A sharp, temporary pain triggered by cold foods or drinks, often indicating exposed dentine or early pulp irritation

""Your sensitivity to cold should settle within two to four weeks as the new filling material hardens and the nerve calms down.""

"treatment plan"

A written proposal outlining all recommended dental procedures, their sequence, and associated costs

"The treatment plan was presented to the patient at the end of the examination, prioritising urgent treatment first."

"oral hygiene instruction"
