Sore and soft teeth are usually caused by dental diseases, in the case of dental caries, for example, which can be treated with a filling modification. In addition, there are treatments for dentin sensitivity, cryptoconjunctivitis and periodontitis, which cause tooth soreness. In addition, if it is caused by medication or bad lifestyle habits, the symptoms can be improved by adjusting the dosage of medication or changing the medication (under doctor’s supervision), paying attention to oral hygiene and avoiding spicy and irritating foods.
