Children are suitable for desensitization treatment. Desensitization treatment is painless, just blow dry the tooth surface and apply desensitizer evenly. If a child’s teeth become sensitive and uncomfortable, they can be treated without affecting their health. It is also possible for children to do this with a relatively low level of cooperation, and generally the whole-mouth desensitization treatment takes less than 5 minutes. Do not brush and rinse your teeth for half an hour to one hour after the desensitization treatment, so that the desensitizer can have time to work and close the dentin tubules.
