Hello Sir. There’s no rule but certainly you should start keeping teeth clean once the teeth erupt . The important part is to not use a fluoride toothpaste in kids below the age of 2 years as they can swallow the toothpaste and ingestion of fluoride is a health hazard. Use a small toothbrush with only pea sized toothpaste. It’s advisable to start using regular toothpaste ( fluoride containing) after 2 years of age.
