Hello Yes go for a toothpaste which contains 1000ppm flouride and go for it

Yes u may but tell him to brush twice a day, avoid sticky food,ask him to do gargle with water after every meal and if possible get the pit and fissure sealant done from your dentist. Regards!

Adult toothpaste contain 1000 PPM fluoride and the kids toothpaste normally contains 450 PPM fluoride. Residents of India, especially North India have high fluoride level of underground water so high level of fluoride in the toothpaste is not required as it can cause mild to moderate staining on the teeth and this is permanent staining which cannot be removed. Although fluoride makes that is stronger but higher than normal dose makes them slightly brittle and aesthetically displeasing. That is why kids toothpaste contain less fluoride to avoid that discoloration while the teeth are being formed inside the bone. After approximately 8 years of age the teeth have been formed and switching to a fluoridated toothpaste will not make much of a difference. A better option will be to use zero fluoride toothpaste which are easily available with the chemist these days till approximately 8 years of age. Regards.

For children aged 3- 6 years the recommendations are to use a fluoridated toothpaste(1000 ppm) in a pea-size amount to reduce the risk of getting cavities(American Dental Association, 2014).The amount is restricted taking into consideration that children younger than 6 years can swallow some amount of toothpaste which may cause mild dental fluorosis. So you may change to the normal toothpastes which contains the recommended concentration of fluoride - 1000 ppm but need to monitor the amount being used by your child. The pediatric toothpastes contain lower concentration of fluoride (500-600 ppm) -  to address the concern of risk of dental fluorosis - but the effectiveness of fluoride at this concentration is not proven.
