In general, the time required to extract a wisdom tooth ranges from 15 minutes to 2 hours, depending on various factors such as the growth condition of the wisdom tooth and the dentist's technical skill. Additionally, the dentist's clinical experience and procedural proficiency can also influence the duration. Experienced dentists are more efficient in handling different wisdom tooth conditions and can shorten the procedure time while ensuring safety.

In general, orthodontic treatment can begin 1 to 3 months after periodontitis therapy, but the exact timing should be determined based on the severity of periodontitis and the individual's recovery progress. If periodontitis is mild, with only symptoms such as gingival redness and swelling and minimal dental calculus, and if gingival inflammation resolves quickly after basic treatment and the oral environment becomes stable, orthodontic suitability can typically be evaluated around one month after treatment.

In general, whether a decayed tooth needs to be extracted depends on the severity of the decay. Mild tooth decay does not require extraction and can be preserved through restorative treatment. However, if the decay has severely damaged the dental pulp or root and cannot be repaired, extraction becomes necessary. It is important to maintain good oral hygiene in daily life, including brushing teeth morning and night, using dental floss, and having regular dental check-ups to detect and treat early-stage cavities promptly.

In general, whether oral ulcer spray can be swallowed depends on the amount ingested. Accidentally swallowing small amounts along with saliva is usually not a cause for concern, but deliberately swallowing large quantities is not recommended. When using oral ulcer spray, strictly follow the dosage instructions, and after spraying, try to hold the medication in the mouth for a moment before swallowing saliva normally, to prolong the drug's effectiveness. At the same time, maintain good oral hygiene.

In general, whether tooth decalcification can be reversed depends on the severity of the condition. Mild decalcification can gradually improve with proper oral care, while severe decalcification, which has already caused structural damage to the tooth, is difficult to fully reverse and requires professional treatment. It is important in daily life to limit sugary foods, reduce consumption of carbonated beverages, rinse the mouth after meals, and prevent food debris from remaining on the tooth surface for prolonged periods.

In general, whether orthodontic treatment is possible with gingival recession depends on the severity and control of the condition. Orthodontic treatment may proceed if the gum recession is mild and inflammation is under control. However, if the recession is severe or the inflammation remains unstable, orthodontics should be postponed until the gum problems are properly treated. Daily oral hygiene practices, including brushing teeth morning and evening, using dental floss to clean between teeth, and regular periodontal checkups and maintenance, are essential.

In general, swelling associated with mumps usually begins about 1 to 2 weeks after infection and typically lasts for 7 to 10 days, although the exact duration may vary slightly depending on the type of infection and individual physical condition. Once symptoms of mumps appear, it is important to rest, avoid consuming acidic or spicy foods, reduce salivary gland secretion, and alleviate pain.

In general, whether dental fillings or root canal treatments can be performed during menstruation depends on the type of treatment. Simple fillings are usually acceptable, but complex root canal procedures are best avoided during menstruation. Extra attention should be paid to oral hygiene during menstruation: brush teeth morning and night, use dental floss regularly, rinse mouth promptly after meals, reduce intake of sugary foods, and prevent worsening of dental problems.
