Children can have their teeth cleaned, but generally children do not need to have their teeth cleaned, only older children with calculus and gingivitis may need to have their teeth cleaned, in addition to cleaning, you can also protect your teeth by brushing them in your daily life. Children can have their teeth cleaned, but for younger children who have not yet had their permanent teeth replaced, or whose permanent teeth have just erupted, there is usually no calculus in the mouth, so there is no need for scaling. Whereas, if the child is older and has the presence of calculus and gingivitis in the mouth, then scaling may be needed to protect the teeth. In daily life, you can let your child brush his/her teeth diligently or use dental floss to clean the gaps between the teeth to protect the teeth. You can use the Pasteur method to brush the teeth, and each time you brush the teeth, you should brush for at least three minutes, once in the morning and once in the evening. If your child needs a dental cleaning, follow your doctor’s instructions.
