I bought a box of dried sweet potatoes the day before yesterday, some hard and sweet. Chew two in the morning and afternoon. When I go to bed at night, I feel that the teeth below are sour, swollen and itchy. It's the same today. Is it tooth allergy? I had pulpitis and filled a tooth with a long-acting drug
If the teeth bite hard objects and have discomfort symptoms, you can take some cefixime and metronidazole for anti-inflammatory treatment, gargle with some Kangfuxin gargle, and observe temporarily. If it doesn't get better for a long time, you can go to the stomatology department of the hospital for film inspection, brush your teeth and gargle with warm water, maintain oral hygiene, and eat more fresh vegetables and fruits.
