1. Clean your baby's mouth and teeth with a wet towel or soft toothbrush every day. Cleaning should start from birth until the baby has its first tooth.
2. Provide your baby with enough liquids, such as water and milk, to keep your mouth moist.
3. Avoid letting the baby suck the bottle or thumb for a long time, which may lead to tooth deformation and jaw dysplasia.
4. Take your baby to the dentist regularly for oral examination and cleaning. Usually the baby can start to see the dentist in about 6 months.
5. If the baby has bad breath, oral ulcer and other problems, seek medical advice promptly.
In short, maintaining oral hygiene and regular examination are the key to protect your baby's oral health.
