When the infection occurs in these locations, it is close to the mouth, which can easily lead to a successive inflammatory reaction of the mucous membrane tissue in the mouth, which can lead to congestion and edema of the gums and soreness of the teeth. This time, you need to go to the dentistry department first, let the dentist do a specific examination of the teeth and gums, to exclude the oral lesions caused by the tooth soreness, such as caries. 2, if there is no obvious lesions, most of the inflammation caused by the cold caused by the tooth soreness. It is better to use anti-inflammatory drugs to relieve it. For the inflammation of teeth and gums, you need to use common antibiotics combined with anti-anaerobic antibiotics, and this time you can use metronidazole combined with amoxicillin to carry out the anti-inflammatory treatment. Some people who are allergic to amoxicillin can also switch to cefixime for anti-inflammatory purposes, and metronidazole can be replaced with ornidazole or tinidazole.
