Toothache is one of the most common symptoms of dental diseases in dentistry, which is manifested by red and swollen gums, painful cold and hot stimulation, and swelling of the cheeks. Toothache in pregnant women may be caused by gingivitis, periodontitis leading to pulp infection, or may be caused by dental caries due to lack of attention to oral cleaning during pregnancy. Since pregnant women are a special group of people, it is usually not recommended to use medication when they have a toothache to avoid affecting the healthy development of the fetus. Therefore, the following methods are recommended to stop the pain quickly: 1. Gargle with concentrated salt water: add appropriate amount of salt to warm water, stir to make it fully dissolve in water, and then gargle twice directly, or use a cotton pad dipped in concentrated salt water to drop on the painful parts; 2. Massage acupuncture points: Chinese medicine believes that the Hegu point has a certain pain-relieving effect on toothache, so when pregnant women have toothache, they can press the Hegu point of both hands to relieve the pain; 3. Other pain relief methods: substances with antiseptic and analgesic effects such as garlic paste, vinegar and ginger can be used according to the situation and applied to the pain location with a cotton swab, so as to achieve pain relief. If the tooth pain of a pregnant woman is serious and the above measures cannot stop the pain, it is recommended to seek medical attention in a timely manner and choose safe and side-effect-free drugs for treatment as appropriate, or actively treat the primary disease after identifying the cause. In addition to active treatment, pregnant women need to pay attention to oral hygiene and develop good habits of brushing teeth in the morning and evening and rinsing mouth after meals. Do not eat too hard food, and eat less acidic, too cold and too hot food to avoid affecting oral health. In addition, regular oral examination should be carried out, and oral diseases such as periodontal disease and dental caries should be actively treated when found.
