Under normal circumstances, toothache water is known in pharmacies as dental pain tincture. The specific analysis is as follows:

Dental pain tincture is a traditional Chinese medicine primarily composed of ingredients such as Piper longum, Alpinia officinarum, Asarum, Clove, and Borneol. It has analgesic, antibacterial, and anti-caries effects. This medication can be used to relieve symptoms such as redness and swelling of the gums, oral heat sensation, dry mouth, and bad breath. In daily life, this medicine is commonly referred to as "toothache water." If experiencing tooth pain, individuals may appropriately use this medication under personal circumstances and medical advice to alleviate symptoms.
To date, adverse reactions are not clearly defined. If using this medication for treatment, it is recommended to do so under the guidance of a healthcare professional to avoid potential adverse effects. During treatment with this medication, avoid consuming raw, cold, spicy, or greasy foods, as these may interfere with drug absorption and reduce its effectiveness. Additionally, during treatment, avoid physical impact or rubbing on the teeth to prevent triggering or worsening discomfort.
In daily life, maintaining good oral hygiene is recommended—brushing teeth morning and night and rinsing the mouth after meals can help improve overall oral health.
