Hello, this article is taken from the article of Nanchang Digital Oral Center, and I hope it will help you. 1. The washed teeth are a little sensitive to cold and heat and feel sour. This symptom is temporary and usually disappears in a week or so. If the sore symptoms persist, you can consider using some anti-sensitive toothpaste sold in the market, which will generally get better after more than one month.

Please don't eat food that is too spicy, too sour or too cold for three days after tooth cleaning. One or two months after tooth cleaning, some people in sensitive person may be allergic to cold, hot, sour and sweet stimuli, which is a normal individual reaction.

3. The main thing to do after tooth washing is self-oral hygiene maintenance, such as brushing your teeth in the right way, flossing, brushing between teeth, etc. Control the formation of dental plaque.

4. After tooth cleaning, please don't suck hard, or lick with your tongue, touch your gums with your fingers, and don't use dental floss or toothpicks for a week to prevent accidental bleeding. For example, after washing your teeth for a period of time, you suddenly bleed for some reason. Please see a doctor in time.
