What Should You Do If It Hurts to Bite After a Filling? Two Things That Distinguish ‘Temporary Sensitivity’ from ‘Time to Return to the Dentist’｜證據鏈

How Long Is It Normal for Biting to Hurt After a Filling?

The literature does not give a clear number of days, and we will not invent one. A useful reference is that one systematic review divided postoperative sensitivity into three intervals — within 30 days, 1 to 1.5 years and 2 to 3 years — and **the risk differences between the two techniques in the latter two intervals were both 0.00** [F1]. That is a difference between techniques, and the abstract reports no incidence for either group, so it cannot tell you how many days your sensitivity will last. In practice, **watching the trend** is more reliable than counting days: if it becomes lighter week by week, it is usually recovering; if it remains unchanged, worsens, or changes in nature (from pain only when biting to spontaneous throbbing), you should return to the dentist for an examination.

充填後に噛むと痛い場合、どれくらいなら正常ですか？ — 文献には明確な日数が示されていないため、任意の目安を作るべきではありません。参考にできるのは、あるシステマティックレビューが術後知覚過敏を 30日間以内、1～1.5 年、2～3 年の3区間に分けて集計し、**後の2区間では 2 つの技法どうしのリスク差がいずれも 0.00** だったことです [F1]。これは技法どうしの差であり、抄録はいずれの群の発生率も報告していないため、知覚過敏が何日続くのかを示すものではありません。 実際には、日数を数えるよりも**傾向を見る**方が信頼できます。週ごとに軽くなるなら通常は回復過程にあります。横ばい、悪化、または痛みの性質が変化した場合（噛んだときだけの痛みから自然な拍動痛へ変わるなど）は、再受診して歯科医師の診査を受けるべきです。
