For dental care methods, the most basic thing is to maintain good oral hygiene, develop good hygiene habits of brushing teeth in the morning and evening, rinsing the mouth after meals, and if necessary, use tools such as dental floss or interdental brushes to thoroughly clean the food residues in the mouth. Usually, you should eat more foods that are good for your teeth, such as more calcium-containing foods, such as milk, chicken, duck, fish, etc. Eating more foods rich in vitamin C can also strengthen the nutrition of the tissues in the mouth. It is also best to go to a dental institution regularly to do a more comprehensive examination of your oral condition, and if any problems are found, to treat them at the earliest possible time. You can also have regular dental scaling to reduce plaque and calculus on the surface of your teeth, which will also make your teeth healthier.
