Ibuprofen sustained-release capsules have antipyretic effects and can also relieve various types of bodily pain, making them a commonly used antipyretic and analgesic medication. Due to their slower onset of action, sustained-release formulations are suitable for mild-to-moderate fever. However, if high fever persists or the patient’s mental status deteriorates, prompt medical evaluation is required to identify the underlying cause of the fever.

Indications for wisdom tooth extraction include recurrent inflammation, dental caries, impingement on adjacent teeth or surrounding tissues, abnormal eruption position, and cystic or other cyst-like lesions. If extensive swelling of the jaw and face or severe trismus occurs, prompt medical evaluation and treatment at a hospital are recommended.

The duration of pain following wisdom tooth extraction varies among individuals. In most cases, pain lasts for 3 to 5 days; however, for impacted wisdom teeth involving more extensive surgical trauma, discomfort may persist for approximately one week. Severe pain lasting longer than one week is typically an abnormal postoperative sign. If intense wound pain is accompanied by a foul odor, prompt medical evaluation is necessary to rule out dry socket (alveolar osteitis).

After wisdom tooth extraction, it is not advisable to consume regular fruits for a short period, as their firm, coarse flesh may scratch the surgical site and dislodge the blood clot. Two hours postoperatively, you may eat lukewarm, mashed fruits. If bleeding from the wound persists or swelling and pain progressively worsen, seek prompt medical attention to have the wound evaluated.

It is safe to undergo professional dental cleaning (scaling) during lactation. Dental cleaning is a localized physical procedure performed in the oral cavity and does not adversely affect breast milk or pose any risk to infants. Delaying treatment of periodontal issues on one’s own is not recommended, as worsening inflammation increases the complexity of subsequent management. Recurrent gingival bleeding and swelling warrant prompt medical evaluation and periodontal treatment.

Teeth cleaning (scaling) can only remove extrinsic stains and dental calculus, restoring teeth to their natural baseline color—but it cannot alter the inherent yellowish hue of teeth. To achieve further tooth whitening, other dental procedures are required. If tooth discoloration is accompanied by sensitivity or structural defects, prompt dental evaluation and oral examination are essential.

It is not recommended to eat immediately after a dental cleaning. Following the procedure, tooth enamel and gums are more sensitive; eating right away may irritate the teeth and gums, and certain foods may contaminate the freshly cleaned tooth surfaces. It is advisable to wait one to two hours before eating. If gum bleeding or severe, persistent tooth pain continues after the cleaning, seek prompt medical evaluation and follow-up care.

Menstruation is not an absolute contraindication for dental scaling; routine scaling can be performed. However, coagulation status changes during menstruation may lead to increased gingival bleeding. Women experiencing heavy menstrual bleeding or severe dysmenorrhea are advised to schedule dental scaling outside their menstrual period. If excessive bleeding occurs during scaling, the procedure should be halted immediately, and a medical evaluation should be conducted.

It is not recommended to self-treat oral ulcers with hydrogen peroxide. Hydrogen peroxide is highly irritating; direct contact with damaged mucosa can exacerbate burning pain and delay wound healing. It should only be used—under a physician’s guidance—to irrigate infected oral wounds. If an ulcer fails to heal over an extended period or the lesion continues to enlarge, prompt medical evaluation is necessary to rule out underlying oral pathology.

It is not recommended to spray Shexiang Bingpian Powder (a traditional Chinese medicine) immediately after tooth extraction, as the medicinal powder may cover the wound, interfere with blood clot formation, and increase the risk of infection. If ulcers or redness and swelling occur in the gums, this medication may be used only after the wound has begun to heal. Persistent bleeding from the extraction site or progressively worsening pain after tooth extraction requires prompt medical attention and professional oral care.
