At what age should kids start cleaning their teeth? As soon as their first tooth protrudes, they should start brushing their teeth. If they are too young then parents can help them by using a piece of cloth to clean their teeth or use a special kid's toothbrush.

How often should they brush their teeth? They should brush their teeth at least twice a day, in the morning and before they go to sleep in the evening. It's very important that they brush their teeth in the evening and after brushing, and they shouldn't eat anything or drink milk, but water is fine.

Apart from the usual dental hygiene methods, do you have any other good tips? Kids can chew gum as it will help reduce cavity levels. If they chew regularly, it will help to develop their jaw muscles. Nowadays, kids eat a lot of soft processed foods, causing their jaw muscles to be under-developed and can cause crowding. They will then need braces so it's good if they practice chewing when they are young. Another way is to use specialist rubber device for them to chew on to help them build up their jaw muscles.
