Sore teeth after scaling can be relieved by eating foods at the right temperature, using anti-allergy toothpaste, and undergoing desensitization treatments. Sore teeth after scaling is due to the fact that after removing calculus and plaque from the teeth, the roots of the teeth are exposed, resulting in sensitivity to hot and cold stimuli and sore teeth. Firstly, you should avoid consuming food or drinks that are too cold or too hot to avoid irritating the tooth pulp. Secondly, you can use toothpastes with anti-allergic effects in your daily life, such as Cold Sour Spirit, or toothpastes like Comfortis, to repair the damaged root surface. If the tooth soreness is obvious and intolerable, you can also go to the hospital and ask the doctor to use anti-allergic medications for coating. These medications can form a protective layer on the surface of the teeth and can relieve the symptoms of sore and sensitive teeth.
