Your child has chocolate very often and drinks frequently during the day and night. So you should definitely meet the dentist when your child is 1 year old. And to check the probable cavities and total health of the gums, visit a dentist when your child is 4 years old and ask the dentist to look for the cavities with X-Ray. Doing this cavity check once your child is 6, is going to be late.
Golden time for prevention for dental treatments
After the age 6, you should be careful of cavities even more. You should prevent anything which may happen to kid's teeth in close future or long-term. The visits between the age 6 and 10 are the most important visits and you should choose the best dentist who can do a great dental diagnose and can advise you very well. If you prevent dental problems well in this period, your child will definitely have a better life.
"If you bring your child to an experienced dentist between the age 6 and 10, you will get rid of 70% of the dental treatments in future"
Your dentist may come up with suggestions such as putting a plastic resin over your child's chewing teeth, this may fit or may not fit your child's conditions. So again you should have chosen a dentist who is experienced enough.
If you're thinking about dental alignment treatments, invisalign, braces, orthodontics or similar treatments, lower ages are definitely better and it takes less for your child to pass the alignment process.
Brush twice a day and consult your dentist about the brush, tooth paste and floss you use.
